afdko

Adobe Font Development Kit for OpenType (AFDKO)

The AFDKO is a set of tools for building OpenType font files from PostScript and TrueType font data.

This repository contains the data files, Python scripts, and sources for the command line programs that comprise the AFDKO. The project uses the Apache 2.0 Open Source license. Please note that the AFDKO makes use of several dependencies, listed in the requirements.txt file, which will automatically be installed if you install AFDKO with pip. Most of these dependencies are BSD or MIT license, with the exception of tqdm, which is MPL 2.0.

Please refer to the AFDKO Overview for a more detailed description of what is included in the package.

Please see the wiki for additional information, such as links to reference materials and related projects.

📣 Recent News

The Python port of psautohint was (re)integrated into the AFDKO repository as "otfautohint"

More information can be found in docs/otfautohint_Notes.md

Installation

The AFDKO requires Python 3.9 or later. It should work with any Python > 3.9, but occasionally tool-chain components and dependencies don't keep pace with major Python releases, so there might be some lag time while they catch up.

Releases are available on the Python Package Index (PyPI) and can be installed with pip.

Note for macOS users: we recommend that you do not use the system Python. Among other reasons, some versions of macOS ship with Python 2 and the latest version of the AFDKO is only available for Python 3. You can find instructions for using Brew to install Python 3 on macOS here: Installing Python 3 on Mac OS X. Also: pyenv is a great tool for installing and managing multiple Python versions on macOS.

Note for all users: we STRONGLY recommend the use of a Python virtual environment (venv) and the use of python -m pip install <package> to install all packages (not just AFDKO). Calling pip install directly can result in the wrong pip being called, and the package landing in the wrong location. The combination of using a venv + python -m pip install helps to ensure that pip-managed packages land in the right place.

Note for Linux users (and users of other platforms that are not macOS or Windows): When there is not a pre-built "wheel" for your platform pip will attempt to build the C and C++ portions of the package from source. This process will only succeed if both the C and C++ development tools and libuuid are installed. See build from source below.

Installing

Option 1 (Recommended)

• Create a virtual environment:

  python -m venv afdko_env
  

• Activate the virtual environment:

  • macOS & Linux

    source afdko_env/bin/activate
    

  • Windows

    afdko_env\Scripts\activate.bat
    

• Install afdko:

  python -m pip install afdko
  

Installing the afdko inside a virtual environment prevents conflicts between its dependencies and other modules installed globally.

Option 2 (not recommended unless there is a global conflict)

Local user installation afdko (info):

python -m pip install --user afdko

Updating

Use the -U (or --upgrade) option to update the afdko (and its dependencies) to the newest stable release:

python -m pip install -U afdko

To get pre-release and in-development versions, use the --pre flag:

python -m pip install -U afdko --pre

Uninstalling

To remove the afdko package use the command:

python -m pip uninstall afdko

Build from source

First you must have installed the development tools for your platform.

On macOS, install these with:

xcode-select --install

On Linux (Ubuntu 17.10 LTS or later), install these with:

apt-get -y install python3.9
apt-get -y install python-pip
apt-get -y install python-dev
apt-get -y install uuid-dev

On other POSIX-like operating systems, libuuid and its header files may be in a package named libuuid-devel or util-linux-libs. The source code for libuuid is maintained in the util-linux repository.

On Windows, you need Visual Studio 2017 or later.

To build the afdko from source, clone the afdko GitHub repository, ensure the wheel module is installed (python -m pip install wheel), then cd to the top-level directory of the afdko, and run:

python -m pip install .

Developing

If you'd like to develop & debug AFDKO using Xcode, run:

CMake -G Xcode .

For further information on building from source see docs/FDK_Build_Notes.md.

Note

It's not possible to install the afdko in editable/develop mode using python -m pip install -e . ; this is because the toolkit includes binary C executables which setup.py tries to install in the bin/ (or Scripts/) folder, however this process was only meant to be used with text-based scripts (either written in Python or a shell scripting language). To work around this problem (which really only impacts the few core afdko developers who need to get live feedback as they modify the source files) you can use alternative methods like exporting a PYTHONPATH, using a .pth file or similar hacks. For further details read this comment.

Major changes from version 2.5.x

• The AFDKO has been restructured so that it can be installed as a Python package. It now depends on the user's Python interpreter, and no longer contains its own Python interpreter.

• Two programs, IS and checkoutlines were dropped because their source code could not be open-sourced. These tools are available in release version 2.5.65322 and older.

Note

If you install the old AFDKO as well as the new PyPI afdko package, the tools from the newer version will take precedence over the older. This happens because pip adds the afdko's package path at the beginning of the system's PATH environment variable, whereas the old installer adds it at the end; this modification to PATH is not undone by the uninstaller. If you want to completely remove the path to the newer version, you will have to edit the PATH. On the Mac, this means editing the line in your login file that sets the PATH variable. On Windows, this means editing the PATH environment variable in the system's Control Panel.

4.0.0 (released 2023-09-11)

The Python port of psautohint was (re)integrated into the AFDKO repository as "otfautohint"

Changes Summary:

• [Name-Change] The name-change better reflects how hinted input is now published, and lets the new version coexist with the old version when needed.
• [AFDKO Tools Updated] Other tools in AFDKO have been updated to call oftautohint instead of psautohint, and the dependency on the latter's repository has been removed.
• [Stopping Psautohint Development] We expect to stop development of psautohint after this v4.0.0 release.
• [Improvements] The new code fixes a number of bugs and in our judgement produces better results on average. It also uses a slightly different encoding in UFO glif files. Accordingly, users should expect that running the new code results in many differences compared with psautohint, but this should be a one-time change.
• [Variable CFF Hinting] The new code also supports hinting of variable CFF-based fonts, including directly hinting a built CFF2 font. Glyphs that include overlap will typically be hinted close to how they would have been hinted with overlap removed.
• [Hinting Time] Because psautohint was partly written in (very old) C code, and otfautohint is written entirely in Python, the new code takes significantly longer to hint an individual glyph. However, we have also enhanced otfautohint to hint different glyphs on multiple CPU cores by default. As a result the tool will be 5-8 times slower when running on a single core but will typically be slightly faster when running on 8 cores.

2.6.25 (released 2018-01-26)

This release fixes the following issues:

• [CheckOutlinesUFO] Skip glyphs whose names are referenced in the UFO's lib but do not exist (#228)
• Partial Python 3 support in BezTools.py, ConvertFontToCID.py, FDKUtils.py, MakeOTF.py, StemHist.py, autohint.py, buildMasterOTFs.py and ufoTools.py (#231, #232, #233)
• [makeotfexe] Fixed parsing of Character Variant (cvXX) feature number (#237)
• [pip] Fixed pip uninstall afdko (#241)

2.6.22 (released 2018-01-03)

The afdko has been restructured so that it can be installed as a Python package. It now depends on the user's Python interpreter, and no longer contains its own Python interpreter.

In order to do this, the two Adobe-owned, non-opensource programs were dropped: IS and checkOutlines. If these turn out to be sorely missed, an installer for them will be added to the old Adobe afdko website. The current intent is to migrate the many tests in checkOutlines to the newer checkOutlinesUFO (which does work with OpenType and Type 1 fonts, but currently does only overlap detection and removal, and a few basic path checks).

Older releases can be downloaded from the repository's Releases page.

2.5.66097 (released 2017-12-01)

This only lists the major bug fixes since the last release. For a complete list see: https://github.com/adobe-type-tools/afdko/commits/master

• [buildCFF2VF] Add version check for fontTools module: only starting with version 3.19.0 does fontTools.cffLib build correct PrivateDict BlueValues when there are master source fonts not at the ends of the axes.
• [makeotfexe] Support mapping a glyph to several Unicode values. This can now be done by providing the the UV values as a comma-separated list in the third field of the GlyphOrderAndAliasDB file, in the 'uniXXXXX' format.
• [makeotfexe] Fixed a crashing bug that can happen when the features file contains duplicate class kern pairs. Reported by Andreas Seidel in email.
• [makeotfexe] Add fatal messages if a feature file 'cvParameters' block is used in anything other than a Character Variant (cvXX) feature, or if a 'featureNames' block is used in anything other than a Stylistic Set (ssXX) feature.
• [makeotfexe] Relaxed restrictions on name table name IDs. Only 2 and 6 are now reserved for the implementation.
• [makeotfexe] Fixed bug where use of the 'size' feature in conjunction with named stylistic alternates would cause the last stylistic alternate name to be replaced by the size feature menu name. Incidentally removed old patent notices.
• [makeotfexe] Restored old check for the fatal error of two different glyphs being mapped to the same character encoding.
• [makeotfexe] If the last line of a GOADB file did not end in a new-line, makeotf quit, saying the line was too long.
• [otf2otc] Can now take a single font as input, and can take an OTC font as input.
• [sfntdiff] Fixed old bug: it used to crash if no file path or only one file path was provided.
• [sfntdiff] Changed behavior: it now returns non-zero only if a real error occurs; it used to return non-zero when there was a difference between the fonts.
• [spot] Fixed old bug: a PrivateDict must exist, but it is legal for it to have a length of 0.
• [tx et al.] Add support for reading and writing blended hints from/to CFF2.

2.5.65811 (released 2017-04-27)

• [makeInstancesUFO] Preserve public.postscriptNames lib key.
• [makeInstancesUFO] Do not use postscriptFontName attribute.
• [makeotf] New option -V to print MakeOTF.py script version.
• [tx] Added new option '-maxs', to set the maximum number of subroutines allowed. The default is now 32K, as some legacy systems cannot support more than this.
• [tx] Add improved CFF2 support: tx can now use the option -cff2 to write from a CFF2 font (in a complete OpenType font) to a file containing the output CFF2 table, with full charstring optimization and subroutinization. This last option is still work in progress: it has not been extensively tested, and does yet support blended hints.
• [tx] Several bug fixes for overlap removal.
• [tx] Fixed bug in subroutinization that could leave a small number of unused subroutines in the font. This cleanup is optional, as it requires 3x the processing speed with the option than without, and typically reduces the font size by less than 0.5 percent.
• [ttxn] Option '-nv' will now print name IDs 3 and 5, but with the actual version number replaced by the string "VERSION SUPPRESSED".
• [ufoTools] FIx autohint bug with UFO fonts: if edit a glyph and re-hint, autohint uses old processed layer glyph.

2.5.65781 (released 2017-04-03)

• [variable fonts] buildMasterOTFs new script to build OTF font files from UFO sources, when building variable fonts.
• [variable fonts] buildCFF2VF new command to build a CFF2 variable font from the master OTF fonts.
• [autohint] Fixed bug introduced by typo on Dec 1 2015. Caused BlueFuzz to always be set to 1. Rarely causes problems, but found it with font that sets BlueFuzz to zero; with BlueFuzz set to 1, some of the alignment zones were filtered out as being closer than BlueFuzz*3.
• [autohint] Fixed long-standing bug with UFO fonts where if a glyph was edited after being hinted, running autohint would process and output only the old version of the glyph from the processed layer.
• [CheckOutlinesUFO] Added "quiet mode" option.
• [CheckOutlinesUFO] Fixed a bug where logic could try and set an off-curve point as a start point.
• [CheckOutlinesUFO] Changed the logic for assigning contour order and start point. The overlap removal changes both, and checkOutlinesUFO makes some attempt to restore the original state when possible. These changes will result in different contour order and start points than before the change, but fixes a bug, and will usually produce the same contour order and start point in fonts that are generated as instances from a set of master designs. There will always be cases where there will be some differences.
• [MakeOTF] Replace old logic for deriving relative paths with python function for the same.
• [MakeOTF] When converting Type 1 to CID in makeotf, the logic in mergeFonts and ConvertFontToCID.py was requiring the FDArray FontDicts to have keys, like FullName, that are not in fact required, and are often not present in the source fonts. Fixed both mergeFonts and ConvertFontToCID.py.
• [MakeOTF] By default, makeotf will add a minimal stub DSIG table in release mode. The new options '-addDSIG' and '-omitDSIG' will force makeotf to either add or omit the stub DSIG table. This function was added because the Adobe Type group is discontinuing signing font files.
• [makeotfexe] Fixed bug in processing UVS input file for makeotf for non-CID fonts.
• [makeotfexe] Fixed bug where makeotf would reject a nameID 25 record when specified in a feature file. This nameID value used to be reserved, but is now used for overriding the postscript family named used with arbitrary instances in variable fonts.
• [mergeFonts] Removed requirement for mergeFonts that each FontDict have a FullName, Weight, and Family Name. This fixes a bug in using mergeFonts with UFO sources and converting to CID-keyed output font. Developers should not have to put these fields in the source fonts, since they are not required.
• [spot] Fixed bug in name table dump: Microsoft platform language tags for Big5 and PRC were swapped.
• [stemHist] Removed debug print line, that caused a lot of annoying output, and was left in the last update by accident.
• [tx] When getting Unicode values for output, the presence of UVS cmap meant that no UV values were read from any other cmap subtable. I fixed this bug, but 'tx' still does not support reading and showing UVS values. Doing so will be a significant amount of work, so I am deferring that to my next round of FDK work.
• [tx] Added support for CFF2 variable fonts as source fonts: when using -t1 or -cff, these will be snapshotted to an instance. If no user design vector (UDV) argument is supplied, then the output will be the default data. If a UDV argument is supplied with the option -U, then the instance is built at the specified point in the design space.
• [tx] Added new option +V/-V to remove overlaps in output Type 1 fonts (mode -t1) and CFF fonts (mode -cff). This is still experimental.
• [tx] Made the subroutinizer a lot faster; the speed bump is quite noticeable with CJK fonts. (by Ariza Michiharu)
• [tx] Added new option (+V/-V) to remove overlaps. (by Ariza Michiharu)
• [ttx] Updated to version 3.9.1 of the fontTools module from master branch on GitHub.

2.5.65322 (released 2016-05-27)

• [CMAP files] Updated UniCNS-UTF32-H to v1.14
• [build] Made changes to allow compiling under Xcode 7.x and OSX 10.11
• [documentation] Fixed a bunch of errors in the Feature File spec. My thanks to Sascha Brawer, who has been reviewing it carefully. See the issues at https://github.com/adobe-type-tools/afdko/issues/created_by/brawer.
• [autohint] Fixed support for history file, which can be used with non-UFO fonts only. This has been broken since UFO support was added.
• [autohintexe] Fixed really old bug: ascenders and descenders get dropped from the alignment zone report if they are a) not in an alignment zone and b) there is an overlapping smaller stem hint. This happened with a lot of descenders.
• [checkOutlines] Fixed bug in ufoTools.py that kept checkOutlines (NOT checkOutlinesUFO) from working with a UFO font.
• [checkOutlines] Fixed bug which misidentified orientation of path which is very thin and in part convex. I am a bit concerned about the solution, as what I did was to delete some logic that was used to double-check the default rules for determining orientation. However, the default logic is the standard way to determine orientation and should always be correct. The backup logic was definitely not always correct as it was applied only to a single point, and was correct only if the curve associated with the point is concave. It is in fact applied at several different points on a path, with the majority vote winning. Since the backup logic is used only when a path is very thin, I suspect that it was a sloppy solution to fix a specific case. The change was tested with several large fonts, and found no false positives.
• [makeInstances] Fixed bug which produced distorted shapes for those glyphs which were written with the Type 1 'seac' operator, a.k.a. Type 1 composite glyphs.
• [makeotfexe] Fixed bug where using both kern format A and B in a single lookup caused random values to be assigned.
• [makeotfexe] Fixed bug where a format A kern value (a single value) would be applied to X positioning rather than Y positioning for the features 'vkrn'. Applied same logic to vpal, valt, and vhal.
• [makeotfexe] Finally integrated Georg Seifert's code for supporting hyphen in development glyph names. This version differs from Georg's branch in that it does not allow any of the special characters in final names (i.e. the left side names in the GlyphAliasAndOrderDB). However, allowing this is a smaller tweak than it used to be: just use the same arguments in cb.c:gnameFinalScan() as in gnameDevScan(). This update also includes Georg's changes for allow source fonts to have CID names in the form 'cidNNNN'.
• [ConvertToCID] Fixed bug that the script expected in several places that the fontinfo file would contain at least one user defined FontDict.
• [ConvertToCID] Fixed bug that the script expected that the source font would have Weight and Adobe Copyright fields in the font dict.
• [makeotf] Fixed a bug that kept the '-nS' option for having any effect when the '-cn' option is used.
• [makeotfexe] Remove use of 'strsep()'; function is not defined in the Windows C library.
• [makeotf] Fixed bug in removing duplicate and conflicting entries. Changed logic to leave the first pair defined out of a set of duplicate or conflicting entries.
• [makeotfexe] Fixed bug in processing GDEF glyph class statements: if multiple GlyphClass statements were used; the additional glyphs were added to a new set of 4 glyph classes, rather than merged with the allowed 4 glyph classes.
• [makeotfexe] Fixed issue in GDEF definition processing. Made it an error to specify both LigCaretByPosition and LigCaretByIndex for a glyph.
• [makeotfexe] Corrected error message: language and system statements are allowed in named lookups within a feature definition, but are not allowed in stand-alone lookups.
• [makeotf] Corrected typo in MakeOTF.py help text about what the default source font path.
• [makeotfexe] Fixed an old bug in makeotf. If a mark-to-base or mark-to-mark lookup has statements that do not all reference the same mark classes, makeotfexe used to write a 'default' anchor attachment point of (0.0) for any mark class that was not referenced by a given statement. Fixed this bug by reporting a fatal error: the feature file must be re-written so that all the statements in a lookup must all reference the same set of mark classes.
• [makeotf] Suppressed warning about not using GOADB file when building a CID font. Some of the changes I made a few weeks ago to allow building fonts with CIDs specified as glyphs names with the form 'cidNNNNN' allowed this warning to be be shown, but it is not appropriate for CID-keyed fonts.
• [makeotf] Fixed old bug where using option -'cn' to convert a non-CID source font to CID would cause a mismatch between the maxp table number of glyphs and the number of glyph actually in the output font, because the conversion used the source font data rather than the first pass name-keyed OTF which had been subject to glyph subsetting with the GOADB file.
• [makeotf] Fixed bug in reading UVS files for non_CID fonts.
• Fixed copyright statements that are incompatible with the open source license. Thanks to Dmitry Smirnov for pointing these out. These were in some make files, an example Adobe CMAP file, and some of the technical documentation.
• Fixed typos in help text in ProofPDF.py. Thank you Arno Enslin.
• [ttxn] Fixed bug in ttxn.py that broke it when dumping some tables, when used with latest fontTools library.
• [tx] Fixed bug in rounding fractional values when flattening library elements, used in design of CJK fonts.
• [tx] Fixed bug in handling FontDict FontMatrix array values: not enough precision was used, so that 1/2048 was written as 1/2049 in some cases.
• [tx] Fixed bug in reading UFO fonts, so that glyphs with no <outline> element and with a <lib> element would be skipped.
• [tx] Minor code changes to allow 'tx' to compile as a 64 bit program.
• [tx] Fixed bug in dumping AFM format data, introduced when tx was updated to be 64 bit.
• [tx] Fixed bug in processing seac, introduced in work on rounding fractional values.
• [tx] Fixed bug in writing AFM files: -1 value would be written as 4294967295 instead of -1.
• [tx] Added option -noOpt, renamed blend operator from 'reserved' to 'blend'. This was done in order to support experiments with multiple master fonts.
• [tx] When reading a UFO font: if it has no Postscript version entry, set the version to 1.0.
• [tx] When writing a UFO font: if StemSnap[H,V] are missing, but Std[H,V]W are present, use the Std[H,V]W values to supply the UFO's postscript StemSnap[H,V] values.
• [tx] Fixed old bug with rounding decimal values for BlueScale is one of the few Postscript values with several places of decimal precision. It is stored as an ASCII text decimal point number in T1, T2, and UFO files, but is stored internally as a C 'float' value in some programs. Real values in C cannot exactly represent all decimal values. For example, the closest that a C 'float' value can come to "0.375" is "0.03750000149".When writing output fonts, tx was writing out the latter value in ASCII text, rather than rounding back to 0.0375. Fixed by rounding to 8 decimal places on writing the value out. This bug had no practical consequences, as 0.0375 and 0.03750000149 both convert to exactly the same float value, but was annoying, and could cause rounding differences in any programs that use higher precision fields to hold the BlueScale value.

2.5.65012 (released 2015-12-01)

• [makeotf] Fixed bug that kept makeotfexe from building fonts with spaces in the path.
• [ConvertFontToCID] Fixed bug that kept makeotf from converting UFO fonts to CID.
• [makeotf] Changed support for Unicode Variation Sequence file (option '-ci') so that when used with name-keyed fonts, the Region-Order field is omitted, and the glyph name may be either a final name or developer glyph name. Added warning when glyph in the UVS entry is not found in font. See MakeOTF User's Guide.
• [makeotfexe] now always makes a cmap table subtable MS platform, Unicode, format 4 for CID fonts. This is required by Windows. If there are no BMP Unicode values, then it makes a stub subtable, mapping GID 0 to UVS 0.
• [tx et al.] When reading a UFO source font, do not complain if the fontinfo.plist entry styleName is present but has an empty string. This is valid, and is common when the style is Regular.

2.5.64958 (released 2015-11-22)

• [autohint/tx] Switched to using new text format that is plist-compatible for T1 hint data in UFO fonts. See header of ufoTools.py for format.

• [autohint] Finally fixed excessive generation of flex hints. This has been an issue for decades, but never got fixed because it did not show up anywhere as a problem. The last version of makeotf turned on parsing warnings, and so now we notice.

• [checkOutlinesUFO] Fixed bug where abutting paths did not get merged if there were no changes in the set of points.

• [checkOutlinesUFO] Fixed bug where a .glif file without an <outline> element was treated as fatal error. It is valid for the <outline> element to be missing.

• [checkOutlines] Changed -I option so that it also turns off checking for tiny paths. Added new option -5 to turn this check back on again.

• [checkOutlinesUFO] Increased max number of paths in a glyph from 64 to 128, per request from a developer.

• [CompareFamily] Fixed old bug in applying ligature width tests for CID fonts, and fixed issue with fonts that do not have Mac name table names. The logic now reports missing Mac name table names only if there actually are some: if there are none, these messages are suppressed.

• [fontplot/waterfallplot/hintplot/fontsetplot] Fixed bugs that prevented these from being used with CID-keyed fonts and UFO fonts. Since the third party library that generates the PDF files is very limited, I did this by simply converting the source files to a name-keyed Type 1 temporary font file, and then applying the tools the temporary file.

• [makeInstancesUFO] Added a call to the ufonormalizer tool for each instance. Also added a call to the defcon library to remove all private lib keys from lib.py and each glyph in the default layer, excepting only "public.glyphOrder".

• Fixed typos in MakeOTF User Guide reported by Gustavo Ferreira

• [MakeOTF] Increased max number of directories to look upwards when searching for GOADB and FontMenuNameDB files from 2 to 3.

• [MakeOTF/makeotfexe] Added three new options:

  • omitMacNames and useMacNames write only Windows platform menu names in name table, apart from the names specified in the feature file. useMacNames writes Mac as well as Windows names.
  • overrideMenuNames allows feature file name table entries to override default values and the values from the FontMenuNameDB for name IDs. NameIDs 2 and 6 cannot be overridden. Use this with caution, and make sure you have provided feature file name table entries for all platforms.
  • skco/nskco do/do not suppress kern class optimization by using left side class 0 for non-zero kern values. Optimizing saves a few hundred to thousand bytes, but confuses some programs. Optimizing is the default behavior, and previously was the only option.

• [MakeOTF] Allow building an OTF from a UFO font only. The internal features.fea file will be used if there is no features file in the font's parent directory. If the GlyphAliasAndOrderDB file is missing, only a warning will be issued. If the FontMenuNameDB is missing, makeotf will attempt to build the font menu names from the UFO fontinfo file, using the first of the following keys found: openTypeNamePreferredFamilyName, familyName, the family name part of the postScriptName, and finally the value NoFamilyName. For style, the keys are: openTypeNamePreferredSubfamilyName, styleName, the style name part of the postScriptName, and finally the value Regular.

• [MakeOTF] Fixed bug where it allowed the input and output file paths to be the same.

• [makeotfexe] Extended the set of characters allowed in glyph names to include + * : ~ ^ !.

• [makeotfexe] Allow developer glyph names to start with numbers; final names must still follow the PS spec.

• [makeotfexe] Fixed crashing bug with more than 32K glyphs in a name-keyed font, reported by Gustavo Ferreira.

• [makeotfexe] Merged changes from Khaled Hosny, to remove requirement that 'size' feature menu names have Mac platform names.

• [makeotfexe] Code maintenance in generation of the feature file parser. Rebuilt the 'antler' parser generator to get rid of a compile-time warning for zzerraction, and changed featgram.g so that it would generate the current featgram.c, rather than having to edit the latter directly. Deleted the object files for the 'antler' parser generator, and updated the read-me for the parser generator.

• [makeotfexe] Fixed really old bug: relative include file references in feature files have not worked right since the FDK moved from Mac OS 9 to OSX. They are now relative to the parent directory of the including feature file. If that is not found, then makeotf tries to apply the reference as relative to the main feature file.

• [spot] Fixed bug in dumping stylistic feature names.

• [spot] Fixed bug proofing vertical features: needed to use vkern values. Fix contributed by Hiroki Kanou.

• [tx et all.] Fix crash when using '-gx' option with source UFO fonts.

• [tx et all.] Fix crash when a UFO glyph point has a name attribute with an empty string.

• [tx et all.] Fix crash when a UFO font has no public.glyphOrder dict in the lib.plist file.

• [tx et all.] Fix really old bug in reading TTF fonts, reported by Belleve Invis. TrueType glyphs with nested component references and x/y offsets or translation get shifted.

• [tx et all.] Added new option '-fdx' to select glyphs by excluding all glyphs with the specified FDArray indices. This and the '-fd' option now take lists and ranges of indices, as well as a single index value.

• Added a command to call the ufonormalizer tool.

• Updated to latest version of booleanOperatons, defcon (ufo3 branch), fontMath (ufo3 branch), fontTools, mutatorMath, and robofab (ufo3 branch). The AFDKO no longer contains any private branches of third party modules.

• Rebuilt the Mac OSX, Linux and Windows Python interpreters in the AFDKO, bringing the Python version up to 2.7.10. The Python interpreters are now built for 64-bit systems, and will not run on 32-bit systems.

2.5.64700 (released 2015-08-04)

• [ufoTools] Fixed bug that was harmless but annoying. Every time that autohint -all was run, it added a new program name entry to the history list in the hashmap for each processed glyph. You saw this only if you opened the hashmap file with a text editor, and perhaps eventually in slightly slower performance.
• [checkOutlinesUFO] Fixed bug where presence of outlines with only one or two points caused a stack dump.
• [makeotf] Fixed bug reported by Paul van der Laan: failed to build TTF file when the output file name contains spaces.
• [spot] Fixed new bug that caused spot to crash when dumping GPOS 'size' feature in feature file format.

2.5.64655 (released 2015-07-17)

• [ufoTools] Fixed bug which placed a new hint block after a flex operator, when it should be before.
• [autohint] Fixed new bug in hinting non-UFO fonts, introduced by the switch to absolute coordinates in the bez file interchange format.
• [ufoTools] Fixed bugs in using hashmap to detect previously hinted glyphs.
• [ufoTools] Fixed bugs in handling the issue that checkOutlinesUFO.py (which uses the defcon library to write UFO glif files) will in some cases write glif files with different file names than they had in the default glyph layer.
• [makeotf] Fixed bug with Unicode values in the absolute path to to the font home directory.
• [makeotf] Add support for Character Variant (cvXX) feature params.
• [makeotf] Fixed bug where setting Italic style forced OS/2 version to be 4.
• [spot] Added support for cvXX feature params.
• [spot] Fixed in crash in dumping long contextual substitution strings, such as in 'GentiumPlus-R.TTF'.
• [tx] Fixed bug in handling CID glyph ID greater than 32K.
• [tx] Changed to write widths and FontBBox as integer values.
• [tx] Changed to write SVG, UFO, and dump coordinates with 2 places of precision when there is a fractional part.
• [tx] Fixed bugs in handling the '-gx' option to exclude glyphs. Fixed problem with CID > 32K. Fixed problem when font has 65536 glyphs: all glyphs after first last would be excluded.
• [tx] Fixed rounding errors in writing out decimal values to cff and t1 fonts.
• [tx] Increased interpreter stack depth to allow for CUBE operators (Library elements) with up to 9 blend axes.
• Fixed Windows builds: had to provide a roundf() function, and more includes for the _tmpFile function. Fixed a few compile errors.
• Fixed bug in documentation for makeInstancesUFO.
• Fixed bug in BezTools.py on Windows, when having to use a temp file.

2.5.64261 (released 2015-05-26)

• [autohintexe] Worked through a lot of problems with fractional coordinates. In the previous release, autohintexe was changed to read and write fractional values. However, internal value storage used a Fixed format with only 7 bits of precision for the value. This meant that underflow errors occurred with 2 decimal places, leading to incorrect coordinates. I was able to fix this by changing the code to use 8 bits of precision, which supports 2 decimal places (but not more!) without rounding errors, but this required many changes. The current autohint output will match the output of the previous version for integer input values, with two exceptions. Fractional stem values will (rarely) differ in the second decimal place. The new version will also choose different hints in glyphs which have coordinate values outside of the range -16256 to +16256; the previous version had a bug in calculating weights for stems.
• [autohint] Changed logic for writing bez files to write absolute coordinate values instead of relative coordinate values. Fixed bug where truncation of decimal values lead to cumulative errors in positions adding up to more than 1 design unit over the length of a path.
• [tx] Fixed bugs in handling fractional values: tx had a bug with writing fractional values that are very near an integer value for the modes -dump, -svg, and -ufo. tx also always applied the logic for applying a user transform matrix, even though the default transform is the identity transform. This has the side-effect of rounding to integer values.

2.5.64043 (released 2015-04-08)

• [checkOutlinesUFO] Added new logic to delete any glyphs from the processed layer which are not in the 'glyphs' layer.

• [makeotf] When building CID font, some error messages were printed twice.

• [makeotf] Added new option stubCmap4. This causes makeotf to build only a stub cmap 4 subtable, with just two segments. Needed only for special cases like AdobeBlank, where every byte is an issue. Windows requires a cmap format 4 subtable, but not that it be useful.

• [makeCIDFont] Output FontDict was sized incorrectly. A function at the end adds some FontInfo keys, but did not increment the size of the dict. Legacy logic is to make the FontInfo dict be 3 larger than the current number of keys.

• [makeInstanceUFO] Changed AFDKO's branch of mutatorMath so that kern values, glyph widths, and the BlueValues family of global hint values are all rounded to integer even when the decimal option is used.

• [makeInstanceUFO] Now deletes the default 'glyphs' layer of the target instance font before generating the instance. This solves the problem that when glyphs are removed from the master instances, the instance font still has them.

• [makeInstanceUFO] Added a new logic to delete any glyphs from the processed layer which are not in the 'glyphs' layer.

• [makeInstanceUFO] Removed the all option: even though mutatorMath rewrites all the glyphs, the hash values are still valid for glyphs which have not been edited. This means that if the developer edits only a few glyphs in the master designs, only those glyphs in the instances will get processed by checkOutlinesUFO and autohint.

• Support fractional coordinate values in UFO workflow:

  • checkOutlinesUFO (but not checkOutlines), autohint, and makeInstancesUFO will now all pass through decimal coordinates without rounding, if you use the new option "decimal". tx will dump decimal values with 3 decimal places.
  • tx already reported fractional values, but needed to be modified to report only 3 decimal places when writing UFO glif files, and in PDF output mode: Acrobat will not read PDF files with 9 decimal places in position values.
  • This allows a developer to use a much higher precision of point positioning without using a larger em-square. The Adobe Type group found that using an em-square of other than 1000 design units still causes problems in layout and text selection line height in many apps, despite it being legal by the Type 1 and CFF specifications.
  • Note that code design issues in autohint currently limit the decimal precision and accuracy to 2 decimal places: 1.01 works but 1.001 will be rounded to 0.

2.5.63782 (released 2015-03-03)

• [tx] Fix bug in reading TTFs. Font version was taken from the name table, which can include a good deal more than just the font version. Changed to read fontRevision from the head table.
• [detype1] Changed to wrap line only after an operator name, so that the coordinates for a command and the command name would stay on one line.
• [otf2otc] Pad table data with zeros so as to align tables on a 4 boundary. Submitted by Cosimo Lupo.

2.5.63718 (released 2015-02-21)

• [ufoTools] Fixed a bug with processing flex hints that caused outline distortion.
• [compareFamily] Fixed bug in processing hints: it would miss fractional hints, and so falsely report a glyph as having no hints.
• [compareFamily] Support processing CFF font without a FullName key.
• [checkOutlinesUFO] Coordinates are written as integers, as well as being rounded.
• [checkOutlinesUFO] Changed save function so that only the processed glyph layer is saved, and the default layer is not touched.
• [checkOutlinesUFO] Changed so that XML type is written as 'UTF-8' rather than 'utf-8'. This was actually a change in the FontTools xmlWriter.py module.
• [checkOutlinesUFO] Fixed typos in usage and help text.
• [checkOutlinesUFO] Fixed hash dictionary handling so that it will work with autohint, when skipping already processed glyphs.
• [checkOutlinesUFO] Fixed false report of overlap removal when only change was removing flat curve
• [checkOutlinesUFO] Fixed stack dump when new glyph is seen which is not in hash map of previously processed glyphs.
• [checkOutlinesUFO] Added logic to make a reasonable effort to sort the new glyph contours in the same order as the source glyph contours, so the final contour order will not depend on (x,y) position. This was needed because the pyClipper library (which is used to remove overlaps) otherwise sorts the contours in (x,y) position order, which can result in different contour order in different instance fonts from the same set of master fonts.
• [makeInstancesUFO] Changed so that the option -i (selection of which instances to build) actually works.
• [makeInstancesUFO] Removed dependency on the presence of instance.txt file.
• [makeInstancesUFO] Changed to call checkOutlinesUFO rather than checkOutlines
• [makeInstancesUFO] Removed hack of converting all file paths to absolute file paths: this was a work-around for a bug in robofab-ufo3k that is now fixed.
• [makeInstancesUFO] Removed all references to old instances.txt meta data file.
• [makeInstancesUFO] Fixed so that current dir does not have to be the parent dir of the design space file.
• Merged fixes from the GitHub AFDKO open source repo.
• Updated to latest version defcon, fontMath, robofab, and mutatorMath.
• Fix for Yosemite (Mac OSX 10.10) in FDK/Tools/setFDKPaths. When an AFDKO script is ran from another Python interpreter, such as the one in RoboFont, the parent Python interpreter may set the Unix environment variables PYTHONHOME and PYTHONPATH. This can cause the AFDKO Python interpreter to load some modules from its own library, and others from the parent interpreters library. If these are incompatible, a crash ensues. The fix is to unset the variables PYTHONHOME and PYTHONPATH before the AFDKO interpreter is called. Note: As a separate issue, under Mac OSX 10.10, Python calls to FDK commands will only work if the calling app is run from the command-line (e.g: open /Applications/RoboFont.app), and the argument shell="True" is added to the subprocess module call to open a system command. I favor also adding the argument stderr=subprocess.STDOUT, else you will not see error messages from the Unix shell. Example: log = subprocess.check_output( "makeotf -u", stderr=subprocess.STDOUT, shell=True).

2.5.63408 (released 2014-12-02)

• [spot] Fixed error message in GSUB chain contextual 3 proof file output; was adding it as a shell comment to the proof output, causing conversion to PDF to fail.
• [makeotf] Increased the limit for glyph name length from 31 to 63 characters. This is not encouraged in shipping fonts, as there may be text engines that will not accept glyphs with more than 31 characters. This was done to allow building test fonts to look for such cases.

2.5.63209 (released 2014-09-18)

• [makeInstancesUFO] Added new script to build instance fonts from UFO master design fonts. This uses the design space XML file exported by Superpolator 3 in order to define the design space, and the location of the masters and instance fonts in the design space. The definition of the format of this file, and the library to use the design space file data, is in the open source mutatorMath library on GitHub, and maintained by Erik van Blokland. There are several advantages of the Superpolator design space over the previous makeInstances script, which uses the Type 1 Multiple Master font format to hold the master designs. The new version a) allows different master designs and locations for each glyph, and b) allows master designs to be arbitrarily placed in the design space, and hence allows intermediate masters. In order to use the mutatorMath library, the AFDKO-supplied Python now contains the robofab, fontMath, and defcon libraries, as well as mutatorMath.
• [ttx] Updated to the latest branch of the fontTools library as maintained by Behdad Esfahbod on GitHub. Added a patch to cffLib.py to fix a minor problem with choosing charset format with large glyph sets.
• Updated four Adobe-CNS1-* ordering files.

2.5.63164 (released 2014-09-08)

• [makeotf] Now detects IsOS/2WidthWeightSlopeOnly as well as the misspelled IsOS/2WidthWeigthSlopeOnly, when processing the fontinfo file.
• [makeotfexe] Changed behavior when 'subtable' keyword is used in a lookup other than class kerning. This condition now triggers only a warning, not a fatal error. Change requested by FontForge developers.
• [makeotf] Fixed bug which prevented making TTF fonts under Windows. This was a problem in quoting paths used with the 'ttx' program.
• Fixed installation issues: removed old Windows install files from the Windows AFDKOPython directory. This was causing installation of a new AFDKO version under Windows to fail when the user's PATH environment variable contained the path to the AFDKOPython directory. Also fixed command file for invoking ttx.py.
• Updated files used for building ideographic fonts with Unicode IVS sequences: FDK/Tools/SharedData/Adobe Cmaps/Adobe-CNS1/Adobe-CNS1_sequences.txt and Adobe-Korea1_sequences.txt.

2.5.62754 (released 2014-05-14)

• [IS/addGlobalColor] When using the '-bc' option, fixed bug with overflow for CID value in dumping glyph header. Fixed bug in IS to avoid crash when logic for glyphs > 72 points is used.
• [makeotfexe] Fixed bug that applied '-gs' option as default behavior, subsetting the source font to the list of glyphs in the GOADB.

2.5.62690 (released 2014-04-30)

• [makeotf] When building output TTF font from an input TTF font, will now suppress warnings that hints are missing. Added a new option '-shw' to suppress these warnings for other fonts that with unhinted glyphs. These warnings are shown only when the font is built in release mode.
• [makeotfexe] If the cmap format 4 UTF16 subtable is too large to write, then makeotfexe writes a stub subtable with just the first two segments. The last two versions allowed using '-' in glyph names. Removed this, as it breaks using glyph tag ranges in feature files.
• Updated copyright, and removed patent references. Made extensive changes to the source code tree and build process, to make it easier to build the open source AFDKO. Unfortunately, the source code for the IS and checkOutlines programs cannot be open sourced.
• [tx/mergeFonts/rotateFont] Removed '-bc' option support, as this includes patents that cannot be shared in open source.
• [tx] All tx-related tools now report when a font exceeds the max allowed subroutine recursion depth.
• [tx/mergeFonts/rotateFont] Added common options to all when possible: all now support UFO and SVG fonts, the '-gx' option to exclude fonts, the '-std' option for cff output, and the '-b' option for cff output.

2.5.61944 (released 2014-04-05)

• [makeotf] Added new option '-gs'. If the '-ga' or '-r' option is used, then '-gs' will omit from the font any glyphs which are not named in the GOADB file.
• [Linux] Replaced the previous build (which worked only on 64-bit systems) with a 32 bit version, and rebuilt checkOutlines with debug messages turned off.
• [ttx] Fixed FDK/Tools/win/ttx.cmd file so that the 'ttx' command works again.

2.5.61911 (released 2014-03-25)

• [makeotf] Add support for two new 'features' file keywords, for the OS/2 table. Specifying 'LowerOpSize' and 'UpperOpSize' now sets the values 'usLowerOpticalPointSize' and 'usUpperOpticalPointSize' in the OS/2 table, and set the table version to 5.
• [makeotf] Fixed the '-newNameID4' option so that if the style name is "Regular", it is omitted for the Windows platform name ID 4, as well as in the Mac platform version. See change in build 61250.
• [tx] When the user does not specify an output destination file path (in which case tx tries to write to stdout), tx now reports a fatal error if the output is a UFO font, rather than crashing.
• [tx] Fixed crash when encountering an empty <dict/> XML element.
• [spot] Added logic to dump the new fields in OS/2 table version 5, usLowerOpticalPointSize and usUpperOpticalPointSize. An example of these values can be seen in the Windows 8 system font Sitka.TTC.
• [ufo workflow] Fixed autohint and checkOutlines so that the '-o' option works, by copying the source UFO font to the destination UFO font name, and then running the program on the destination UFO font.
• [ufo workflow] Fixed tools that the PostScript font name is not required.
• Added Linux build.

2.5.61250 (released 2014-02-17)

• [tx] Fixed rare crashing bug in reading a font file, where a charstring ends exactly on a refill buffer boundary.
• [tx] Fixed rare crashing bug in subroutinization.
• [tx] Fixed bug where it reported values for wrong glyph with more than 32K glyphs in the font.
• [tx] Fixed bug where the tool would not dump a TrueType Collection font file that contained OpenType/CFF fonts.
• [tx] Fixed issue where it failed to read a UFO font if the UFO font lacked a fontinfo.plist file, or a psFontName entry.
• [IS] Fixed IS so that it no longer scales the fontDict FontMatrix, when a scale factor is supplied, unless you provide an argument to request this.
• [makeotf] The option '-newNameID4' now builds both Mac and Win name ID 4 using name ID 1 and 2, as specified in the OpenType spec. The style name is omitted from name ID 4 it is "Regular".
• [makeotf] Changed logic for specifying ValueFormat for PosPair value records. Previous logic always used the minimum ValueFormat. Since changing ValueFormat between one PosPair record and the next requires starting a new subtable, feature files that used more than one position adjustment in a PosPair value record often got more subtable breaks then necessary, especially when specifying a PairPos statement with an all zero Value Record value after a PairPos statement with a non-zero Value Record. With the new logic, if the minimum ValueFormat for the new ValueRecord is different than the ValueFormat used with the ValueRecord for the previous PairPos statement, and the previous ValueFormat permits expressing all the values in the current ValueRecord, then the previous ValueFormat is used for the new ValueRecord.
• Added commands otc2otf and otf2otc to build OpenType collection files from a OpenType font files, and vice-versa.
• [ttx] Updated the FontTools library to the latest build on the GitHub branch maintained by Behdad Esfahbod, as of Jan 14 2014.
• [ufo workflow] Fixed bugs in ufoTools.py. The glyph list was being returned in alphabetic order, even when the public.glyphOrder key was present in lib.py. Failed when the glyphOrder key was missing.

2.5.60908 (released 2013-10-21)

• [tx] Can now take UFO font as a source font file for all outputs except rasterization. It prefers GLIF file from the layer glyphs.com.adobe.type.processedGlyphs. You can select another preferred layer with the option '-altLayer <layer name>'. Use 'None' for the layer name in order to have tx ignore the preferred layer and read GLIF files only from the default layer.
• [tx] Can now write to a UFO with the option '-ufo'. Note that it is NOT a full UFO writer. It writes only the information from the Postscript font data. If the source is an OTF or TTF font, it will not copy any of the meta data from outside the font program table. Also, if the destination is an already existing UFO font, tx will overwrite it with the new data: it will not merge the new font data with the old.
• [tx] Fixed bugs with CID values > 32K: used to write these as negative numbers when dumping to text formats such as AFM.
• [autohint/checkOutlines] These programs can now be used with UFO fonts. When the source is a UFO font, the option '-o' to write to another font is not permitted. The changed GLIF files are written to the layer 'glyphs.com.adobe.type.processedGlyphs'. Each script maintains a hash of the width and marking path operators in order to be able to tell if the glyph data in the default layer has changed since the script was last run. This allows the scripts to process only those glyphs which have changed since the last run. The first run of autohint can take two minutes for a 2000 glyph font; the second run takes less then a second, as it does not need to process the unchanged glyphs.
• [stemHist/makeotf] Can now take UFO fonts as source fonts.

2.5.60418 (released 2013-02-26)

• [autohint] Now skips comment lines in fontinfo file.
• [makeotf] Added support for source font files in the 'detype1' plain text format. Added logic for "Language" keyword in fontinfo file; if present, will attempt to set the CID font makeotf option -"cs" to set he Mac script value.
• [compareFamily] Added check in Family Test 10 that font really is monospaced or not when either the FontDict isFixedPitch value or the Panose value says that it is monospaced.
• [spot] Fixed bug that kept 'palt'/'vpal' features from being applied when proofing kerning.

2.5.59149 (released 2012-10-31)

• [makeotf] When building OpenType/TTF files, changed logic to copy the OS/2 table usWinAscent/Descent values over the head table yMax/yMin values, if different. This was because:

  • both pairs are supposed to represent the real font bounding box top and bottom,and should be equal;
  • the TTF fonts we use as sources for makeotf are built by FontLab;
  • FontLab defines the font bounding box for TrueType fonts by using off-curve points as well as on-curve points. If a path does not have on-curve points at the top and bottom extremes, the font bounding box will end up too large. The OS/2 table usWinAscent/Descent values, however, are set by makeotf using the converted T1 paths, and are more accurate. Note that I do not try to fix the head table xMin and xMax. These are much less important, as the head table yMin and yMax values are used for line layout by many apps on the Mac, and I know of no application for the xMin and yMin values.

• [makeotf] Changed default Unicode H CMAP file for Adobe-Japan1 CID fonts to use the UniJIS2004-UTF32-H file.

• Added the CID font vertical layout files used with KozMinPr6N and KozGoPr6N: AJ16-J16.VertLayout.KozGo and AJ16-J16.VertLayout.KozMin.

• Updated several Unicode CMAP files, used only with CID fonts.

• Added new Perl script, glyph-list.pl, used in building CID fonts. This replaces the three scripts extract-cids.pl, extract-gids.pl, and extract-names.pl, which have been removed from the AFDKO.

2.5.58807 (released 2012-09-13)

• [makeotf] Discovered that when building TTF fonts, the GDEF table was not being copied to the final TTF font file. Fixed.

2.5.58732 (released 2012-09-04)

• [autohint] Added new feature to support sets of glyphs with different baselines. You can now specify several different sets of global alignment zones and stem widths, and apply them to particular sets of glyphs within a font when hinting. See option '-hfd' for documentation.

• [autohint] Allow AC to handle fonts with no BlueValues, aka alignment zones.

• [autohint] Respect BlueFuzz value in font.

• [autohint] Fixed the options to suppress hint substitution and to allow changes.

• [autohint] When hinting a font with no alignment zones or invalid alignment zones (and with the '-nb' option), set the arbitrary alignment zone outside the FontBBox, rather than the em-square.

• [checkOutlines] Fixed bug where the arms of an X would be falsely identified as coincident paths, when they are formed by only two paths with identical bounding boxes.

• [checkOutlines] Fixed bug where very thin elements would get identified as a tiny sub path, and get deleted.

• [checkOutlines] Fixed bug in determining path orientation. Logic was just following the on-path points, and could get confused by narrow concave inner paths, like parentheses with an inner contour following the outer contour, as in the Cheltenham Std HandTooled faces.

• [checkOutlines] Fixed bugs in determining path orientation. Previous logic did not handle multiple inner paths, or multiple contained outer paths. Logic was also dependent on correctly sorting paths by max Y of path bounding box. Replaced approximations with real bezier math to determine path bounding box accurately.

• [checkOutlines] Changed test for suspiciously large bounding box for an outline. Previous test checked for glyph bounding box outside of fixed limits that were based on a 1000 em square. The new test looks only for paths that are entirely outside a rectangle based on the font's em square, and only reports them: it does not ever delete them. Added new option '-b' to set the size of the design square used for the test.

• [checkOutlines] Fixed bug where it would leave a temp file on disk when processing a Type 1 font.

• [checkOutlines] Removed test for coincident control points. This has not been an issue for decades. It is frequently found in fonts because designers may choose to not use one of the two control points on a curve. The unused control point then has the same coordinates as its nearest end-point, and would to cause checkOutlines to complain.

• [compareFamily] Single Test 6. Report error if there is a patent number in the copyright. Adobe discovered that a company can be sued if it ships any product with an expired patent number.

• [compareFamily] Single Test 22 (check RSB and LSB of ligature vs. the left and right ligature components) did not parse contextual ligature substitution rules correctly. Now fixed.

• [compareFamily] Family Test 18. Survive OTF fonts with no blue values.

• [compareFamily] Family Test 2 (Check that the Compatible Family group has same nameIDs in all languages): Added the WPF nameIDs 21 and 22 to the exception list, which may not exist in all faces of a family.

• [fontsetplot] Fixed so it works with CID fonts. Also fixed so that widow line control works right. Added new low level option for controlling point size of group header.

• [fontsetplot] Fixed syntax of assert statements. Produced error messages on first use of the *plot commands.

• [kernCheck] Fix so that it survives fonts with contextual kerning. It does not, however, process the kern pairs in contextual kerning.

• [makeotf] Fixed bug in mark to ligature. You can now use an <anchor NULL> element without having to follow it by a dummy mark class reference.

• [makeotf] Fixed bug which limited source CID fonts to a maximum of 254 FDArray elements, rather than the limit of 255 FDArray elements that is imposed by the CFF spec.

• [makeotf] Fixed bugs in automatic GDEF generation. When now GDEF is defined, all conflicting class assignments in the GlyphClass are filtered out. If a glyph is assigned to a make class, that assignment overrides any other class assignment. Otherwise, the first assignment encountered will override a later assignment. For example, since the BASE class is assigned first, assignment to the BASE class will override later assignments to LIGATURE or COMPONENT classes.

• [makeotf] Fix bug in validating GDEF mark attachment rules. This now validates the rules, rather than random memory. Had now effect on the output font, but did sometimes produce spurious error messages.

• [makeotf] Fix crashing bug when trying to report that a glyph being added to a mark class is already in the mark class.

• [makeotf] If the OS/2 code page bit 29 (Macintosh encoding) is set, then also set bit 0 (Latin (1252). Under Windows XP and Windows 7, if only the Mac bit is set, then the font is treated as having no encoding, and you cannot apply the font to even basic Latin text.

• [makeotf] By default, set Windows name ID 4 (Full Name) same as Mac nameID 4, instead of setting it to the PostScript name. This is in order to match the current definition of the name ID 4 in the latest OpenType spec. A new option to makeotf ('-useOldNameID4'), and a new key in the fontinfo file ("UseOldNameID4"), will cause makeotf to still write the PS name to Windows name ID 4.

• [makeotf] Add support for WPF names, name ID 21 and 22.

• [makeotf] Fixed attachment order of marks to bug in generating Mark to Ligature (GPOS lookup type 4). The component glyphs could be reversed.

• [makeotf] Fixed bug in auto-generating GDEF table when Mark to Mark (GPOS lookup Type 4) feature statements are used. The target mark glyphs were registered as both GDEF GlyphClass Base and Mark glyphs, and the former took precedence. makeotfexe now emits a warning when a glyph gets assigned to more than one class when auto-generating a GDEF table GlyphClass, and glyphs named in mark to mark lookups are assigned only to the Mark GDEF glyph class.

• [makeotf] Fixed bugs in generating TTF fonts from TTF input. It now merges data from the head and hhea tables, and does a better job of dealing with the 'post' table. The previous logic made incorrect glyph names when the glyphs with names from the Mac Std Encoding were not all contiguous and at the start of the font.

• [makeotf] Added new option '-cn' for non-CID source fonts, to allow reading multiple global font alignment zones and stem widths from the fontinfo file, and using this to build a CID-keyed CFF table with an identity CMAP. This is experimental only; such fonts may not work in many apps.

• [makeotf] Fixed bug where the coverage table for an element in the match string for a chaining contextual statement could have duplicate glyphs. This happens when a glyph is specified more than once in the class definition for the element. The result is that the format 2 coverage table has successive ranges that overlap: the end of one range is the same glyph ID as the start of the next range; harmless, but triggers complaints in font validators.

• [makeotf] Updated to latest Adobe CMAP files for ideographic fonts. Changed name of CMAP directories in the AFDKO, and logic for finding the files.

• [makeotf] When providing a GDEF feature file definition, class assignments now may be empty:

    table GDEF {
        GlyphClassDef ,,,;
    } GDEF;
  

  is a valid statement. You just need to provide all three commas and the final colon to define the four classes. The following statement builds a GDEF GlyphClass with an empty Components class.

    table GDEF {
        GlyphClassDef [B], [L], [M], ;
    } GDEF;
  

• [makeotf] The glyph alias file now defines order in which glyphs are added to the end of the target font, as well as defining the subset and renaming.

• [makeotf] The -cid <cidfontinfo> option for converting a font to CID can now be used without a glyph alias file, if the source font glyphs have names in the form "cidXXXX", as is output when mergeFonts is used to convert from CID to name-keyed. If the -cid <cidfontinfo> option is used, and there is no glyph alias file, then any glyphs in the font without a name in the form "cidXXXX" will be ignored.

• [spot] Added error message for duplicate glyph IDs in coverage tables with format 2, a problem caused by a bug in makeotf with some Adobe fonts that use chaining contextual substitution. Note: error message is written only if level 7 GSUB/GPOS dump is requested.

• [spot] Minor formatting changes to the GSUB/GPOS level 7 dump, to make it easier to edit this into a real feature file.

• [spot] When writing out feature file syntax for GPOS 'ignore pos' rules, the rule name is now written as 'ignore pos', not just 'ignore'.

• [spot] Can now output glyph names up to 128 chars (Note: these are not legal PostScript glyph names, and should be encountered only in development fonts.)

• [spot] Has new option '-ngid' which suppresses output of the trailing glyph ID @<gid> for TTF fonts.

• [spot] No longer dumps the DefaultLangSys entry when there is none.

• [spot] Changed dump logic for contextual and chain contextual lookups so that spot will not dump the lookups referenced by the substitution or position rules in the contextual lookups. The previous logic led to some lookups getting dumped many times, and also to infinite loops in cases where a contextual lookup referenced other contextual lookups.

• [spot] Added support for Apple kern subtable format 3. Fixed old bug causing crash when dumping font with Apple kern table from Windows OS.

• [spot] Fixed error when dumping Apple kern table subtable format 0, when kern table is at end of font file.

• [spot] Fixed crashing bug seen in DejaVuSansMono.TTF: spot did not expect an anchor offset to be zero in a Base Array base Record.

• [spot] Removed comma from lookupflag dump, to match feature file spec.

• [spot] Added logic to support name table format 1, but it probably does not work, since I have been unable to find a font to test with this format.

• [spot] Fixed spelling error for "Canadian" in OS/2 code page fields.

• [spot] Changed dump of cmap subtable 14: hex values are uppercased, and base+UVS values are written in the order [base, uvs].

• [stemHist] Always set the alignment zones outside the font BBox, so as to avoid having the source font alignment zones affect collection of stem widths.

• [stemHist] Fix bug where the glyph names reported in the stem and alignment reports were off by 1 GID if the list of glyphs included the '.notdef' glyph.

• [tx] Added support for option '-n' to remove hints for writing Type 1 and CFF output fonts.

• [tx] Added new option "+b" to the cff output mode, to force glyph order in the output font to be the same as in the input font.

• [tx] Fixed bug in flattening 'seac' operator. If the glyph components were not in the first 256 glyphs, then the wrong glyph would be selected.

• [tx] Added new library to read in svg fonts as a source. tx can now read all the SVG formats that it can write. Handles only the path operators: M, m, L, L, C, c, Z, z, and the font and glyph attributes: 'font-family', 'unicode', 'horiz-adv-x', 'glyph-name', 'missing-glyph'.

• [tx] Fixed bug in converting TTF to OpenType/CFF. It flipped the sign of the ItalicAngle in the 'post' table, which in turn flipped the sign of the OS/2 table fields ySubscriptXOffset and ySuperscriptXOffset. This bug showed up in TTF fonts built by makeotf, as makeotf uses 'tx' to build a temporary Type 1 font from the source TTF.

• [tx] Fixed bug where '-usefd' option was not respected, when converting from CID to name-keyed fonts.

• Updated the internal Python interpreter to version 2.7.

• Updated Adobe Cmaps/Adobe-Japan1 files:

  • Adobe-Japan1_sequences.txt
  • UniJIS-UTF32-H
  • UniJIS2004-UTF32-H
  • UniJISX0213-UTF32-H
  • UniJISX02132004-UTF32-H

• Added several scripts related to CID font production:

  • cmap-tool.pl
  • extract-cids.pl
  • extract-gids.pl
  • extract-names.pl
  • fdarray-check.pl
  • fix-fontbbox.pl
  • hintcidfont.pl
  • subr-check.pl

2.5.25466 (released 2012-03-04)

• [charplot] This was non-functional since build 21898. Now fixed.
• [checkOutlines] Changed so that the test for nearly vertical or horizontal lines is invoked only if the user specifies the options '-i' or '-4', instead of always. It turns out that this test, when fixed automatically, causes more problems than it cures in CJK fonts.
• [compareFamily] Changed so that the default is to check stem widths and positions for bogus hints. Used 'tx' rather than Python code for parsing charstring in order to speed up hint check.
• [compareFamily] Updated script tags and language tags according to OpenType specification version 1.6.
• [documentation] In feature file syntax reference, fixed some errors and bumped the document version to 1.10.
• [documentation] Fixed typo in example in section 4.d: lookFlag values are separated by spaces, not commas.
• [documentation] Fixed typo in example in section 8.c on stylistic names: quotes around name string need to be matching double quotes. Reported by Karsten Luecke.
• [documentation] Changed agfln.txt copyright notice to BSD license.
• [makeInstances] Fixed bug where a space character in any of the path arguments caused it to fail.
• [makeInstances] Fixed bug that can make the FontBBox come out wrong when using ExtraGlyphs.
• [makeInstances] Fixed rounding bug that could (rarely) cause makeInstances to think that a composite glyph is being scaled (which is not supported by this script) when it is not.
• [makeotf] Fixed bug in generating TTF fonts from TTF input. Previous version simply did not work.
• [spot] Added support for "Small" fonts, an Adobe internal Postscript variant used for CJK fonts.
• [spot] Added support for large kern tables, such as in the Vista font Cambria, where the size of the kern subtable exceeds the value that can be held in the subtable "length" field. In this case, the "length" filed must be ignored.
• [spot] Fixed proof option to show GPOS records in GID order by default, and in lookup order only with the '-f' option. It had always been proofing the GPOS rules in lookup order since 2003.
• [spot] Fixed double memory deallocation when dumping TTC files; this could cause a crash.
• [spot] When decompiling GSUB table to feature file format (-t GSUB=7) and reporting skipped lookups identify lookups which are referenced by a chaining contextual rule.
• [sfntedit] Changed final "done" message to be sent to stdout instead of stderr. Reported by Adam Twardoch.
• [stemHist] Fixed typo in help text, reported by Lee Digidea: '-all' option was not working.
• [tx] Added new option '-std' to force StdEncoding in output CFF fonts.

2.5.21898 (released 2009-05-01)

• [autohint/checkOutlines] Fixed rare case when an rrcurveto is preceded by such a long list of rlineto that the stack limit is passed.
• [autohint/checkOutlines] Fixed to restore font.pfa output file to StandardEncoding Encoding vector. Since requirements of CFF StandardEncoding differs from Type 1 StandardEncoding, a StandardEncodingEncoding vector in a Type 1 font was sometimes getting converted to a custom Encoding vector when being round-tripped through the CFF format which autohint does internally.
• [checkOutlines] Fixed random crash on Windows due to buffer overrun.
• [checkOutlines] Changed default logging mode to not report glyph names when there is no error report for the glyph.
• [CompareFamily] Added "ring" to the list of accent names used to find (accented glyph, base glyph) pairs for Single Face Test 23. Reported by David Agg.
• Renamed showfont to fontplot2 to avoid conflict with the Mac OSX showfont tool.
• Fixed problem with showing vertical origin and advance: was not using VORG and vmtx table correctly.
• [FontLab scripts] Added logic to Instance Generator to support eliminating "working" glyphs from instances, to substitute alternate glyph designs for specific instances, and to update more Font Dict fields in the instance fonts. Added help.
• Added command line equivalent, "makeInstances' which does the same thing, but which uses the IS tool for making the snapshot. See the 'IS' entry.
• [IS] Added new tool for "intelligent scaling". This uses the hinting in an MM font to keep glyph paths aligned when snapshotting from MM fonts. The improvement is most visible in glyphs with several elements that need to maintain alignment, such as percent and perthousand. It is also useful for the same reason when scaling fonts from a large em-square size to a smaller size. To be effective, the source MM font must be hinted and must have global alignment zones defined. The new font must be re-hinted. For instances from MM fonts especially, it is a good idea to redo the alignment zones, as the blending of the MM base designs usually does not produce the best alignment zones or stem widths for the instance fonts. makeInstances and "Instance Generator" scripts allow you to preserve these modifications when redoing the MM instance snapshot.
• [makeotf] Fixed generation of version 1.2 GDEF table to match the final OpenType spec version 1.6. This version is generated only when the new lookup flag 'UseMarkFilteringSet" is used.
• [makeotf] Fixed generation of names for stylistic alternates features. There was a bug such that in some circumstances, the feature table entry for the stylistic alternate feature would point to the wrong lookup table.
• [makeotf] Fixed generation of the reverse substitution lookup type. This was unintentionally disabled just before the previous release.
• [makeotf] Fixed bugs in memory management of glyph objects. If the font built, it was correct, but this bug could cause the font to fail to build.
• [spot] Fixed to dump GDEF table version 1.2 according to the final OpenType spec version 1.6.
• [spot] Fixed feature-format dump of the lookupflags MarkAttachmentType and UseMarkFilteringSet to give a class name as an argument, rather than a class index.
• [spot] Extended the GDEF table dump to provide a more readable form.
• [spot] Added dump formats for htmx and vtmx to show the advance and side bearing metrics for all glyphs.

2.5.21340 (released 2009-01-22)

• [AGLFN] (Adobe Glyph List for New Fonts) Created new version 1.7.

• [AGLFN] Reverted to the AGLFN v1.4 name and Unicode assignments for Delta, Omega, and mu. The v1.6 versions were better from a designer's point of view, but we cannot use name-to-Unicode value mappings that conflict with the historic usage in the Adobe Glyph List 2.0. See http://www.adobe.com/devnet/opentype/archives/glyph.html.

• [AGLFN] Dropped all the 'afii' names from the list: 'uni' names are actually more descriptive, and map to the right Unicode values under Mac OSX.

• [AGLFN] Dropped all the 'commaccent' names from the list: 'uni' names map to the right Unicode values under Mac OSX before 10.4.x.

• [autohint] Converted AC.py script to call a command-line program rather than a Python extension module, same way makeotf works, to avoid continuing Python version problems.

• [autohint] Fixed to actually emit vstem3 and hstem3 hint operators (counter control hints, which work to keep the space between three stems open and equal, as in an 'm') - this has been broken since the first AFDKO. It will now also look in the same directory as the source font for a file named "fontinfo", and will attempt to add stem3 hints to the glyph which are listed by name in the name list for the keys "HCounterChars" or "VCounterChars".

• [autohint] Fixed old bug where it would only pay attention to the bottom four of the top zone specified in the FontDict BlueValues list. This results in more edge hints in tall glyphs.

• [autohint] Fixed special case when adding flex operator which could result in an endless loop

• [autohint] Added 'logOnly' option, to allow collecting report without changing the font.

• [autohint] Added option to specify which glyphs to exclude from autohinting.

• [autohint] Suppressed generation and use of <font-name>.plist file, unless it is specifically requested.

• [autohint] Fixed bug where an extremely complex glyph would overflow a buffer of the list of hints.

• [checkOutlines] Improved overlap detection and path orientation: it will now work with outlines formed by overlapping many stroke elements, as is sometimes done in developing CJK fonts.

• [checkOutlines] added new test for nearly vertical or horizontal lines. Fixed bug in this new code, reported by Erik van Blokland.

• [CompareFamily] For the warning that the Full Family name in the CFF table differs from that in the name table, changed it to a "Warning" rather than "Error", and explained that there is no functional consequence.

• [CompareFamily] Removed check that Mac names ID 16 and 17 do not exist, as makeotf now does make them. See notes in MakeOTF User Guide about this.

• [CompareFamily] Fixed so it works with TTF fonts again.

• [makeotf] Removed code that added a default Adobe copyright to the name table if no copyright is specified, and removed code to add a default trademark.

• [makeotf] Added support for the lookupflag UseMarkFilteringSet. This is defined in the proposed changes for OpenType spec 1.6, and is subject to change in definition.

• [makeotf] Dropped restriction that vmtx/VORG/vhea tables will only be written for CID-keyed fonts. The presence in the feature file of either a 'vrt2' feature of vmtx table overrides will now cause these tables to be written for both CID-keyed and name-keyed fonts.

• [makeotf] Added warning when a feature is referenced in the aalt feature definition, but either does not exist or does not contribute any rules to the aalt feature. The aalt feature can take only single and alternate substitution rules.

• [makeotf] Added support for the following lookup types:

  • GSUB type 2 Multiple Substitution
  • GSUB type 8 Reverse Chaining Single Substitution
  • GPOS type 3 Cursive Adjustment
  • GPOS type 4 Mark-to-Base Attachment
  • GPOS type 5 Mark-to-Ligature Attachment
  • GPOS type 6 Mark-to-Mark Attachment

• [makeotf] Added support for explicit definition of the GDEF table, and automatic creation of the GDEF when any of the lookup flag settings for ignoring a glyph class is used, or any mark classes are defined.

• [makeotf] Support using TTF fonts as input, to build an OpenType/TTF font, with the limitation that glyph order and glyph names cannot be changed. This is rather ugly under the hood, but it works. The MakeOTF.py Python script uses the tx tool to convert the TTF font to CFF data without changing glyph order or names. It then builds an OpenType/CFF font. It then uses the sfntedit tool to copy the TTF glyph data to the OpenType font, and to delete the CFF table.

• [makeotf] Added support for building Unicode Variation Selectors for CID-keyed fonts, using the new cmap subtable type 14.

• [makeotf] Fixed bug with inheritance of default rules by scripts and languages in feature file feature definitions. Explicitly defined languages were only getting default rules defined after the last script statement, and when a script is named, languages of the script which are not named got no rules at all.

• [makeotf] Fixed bug where you could not run makeotf when the current directory is not the same is the source font's home directory.

• [makeotf] Set OS/2.lastChar field to U+FFFF when using mappings beyond the BMP.

• [makeotf] Create the Mac platform name table font menu names by the same rules as used for the Windows menu names. Add new keywords to the FontMenuNameDB file syntax. If you use the old keywords, you get the old format; if you use the new syntax, you get nameIDs 1, 2 and 16 and 17 just like for the Windows platform.

• [makeotf] Fixed bug in name table font menu names: if you entered a non-English Preferred name ("f=") and not a compatible family name ("c="), you would end up with a nameID 16 but no nameID 17.

• [makeotf] Fixed bogus 'deprecated "except" syntax' message under Windows.

• [makeotf] Fixed bug where contextual pos statements without backtrack or lookahead context were writing as a non-contextual rule. Reported by Karsten Luecke.

• [makeotf] Added new option to make stub GSUB table when no GSUB rules are present.

• [makeotf] Added warning if the aalt feature definition references any feature tags that either do not exist in the font, or do not contribute any rules that the aalt feature can use.

• [sfntdiff] Fixed so that only error messages are written to stderr; all others now written to stdout.

• [sfntdiff] Fixed bug in dump of 'name' table: when processing directories rather than individual files, the name table text was never updated after the first file for the second directory.

• [spot] Fixed option '-F' to show the contextual rule sub-lookup indices, and to flag those which have already been used by another lookup.

• [spot] If a left side class 0 is empty, do not report it.

• [spot] For GSUB/GPOS=7 FEA dump, give each class a unique name in the entire font by appending the lookup ID to the class names. It was just [LEFTCLASS]()<class index>_<subtable index>, but these names are repeated in every lookup. It is now LEFTCLASS_c<class index>_s<subtable index>_l<lookup index>.

• [spot] When a positioning value record has more than one value, print the full 4 item value record. Previously, it would just print non-zero values. This was confusing when dumping Adobe Arabic, as you would see two identical values at the end of some pos rules. In fact, each of these pos rule does have two adjustment values, one for x and one for y advance adjustment, that happen to be the same numeric value.

• [spot] Fixed to write backtrack context glyphs in the right order.

• [tx] Added option to NOT clamp design coordinates to within the design space when snapshotting MM fonts.

• [tx] Added option to subroutinize the font when writing to CFF. This option is derived from the same code used by makeotfexe, but takes only about 10% the memory and runs much faster. This should allow subroutinizing large CJK fonts that makeotfexe could not handle. This is new code, so please test results carefully, i.e. if you use it, always check that the flattened glyphs outlines from the output font are identical to the flattened glyph outlines from the input font.

• [ttxn] Added options to suppress hinting in the font program, and version and build numbers.

2.0.27 (released 2007-11-10)

• [compareFamily] Fixed Single Test 3 (reported by Mark Simonson and others); the test should compare the Mac platform name ID 4 (name ID 1 + space + name ID 2) with the target value, but was instead using the value of the name ID 18 (Compatible Full Name).
• [compareFamily] Fixed Family Test 2 to print a report that helps determine which {platform, script, language, name ID} is present in some fonts but not others.
• [IS] Fixed a bug where applying hint-based scaling can cause an off-by-1 error when the the closepath position is supposed to coincide with the original moveto, leading to an effective final 1-unit lineto, that may overlap the initial path. In the old MM design world, we worked around this issue by designing the MMs so that there was always a one unit difference between a final curveto point and the original moveto. FontLab doesn't support doing that automatically, so when making an instance, IS will instead simply look for cases where the moveto and closepath positions differ by one unit, and move the moveto position to coincide with the closepath position.
• [makeotf] Fixed bug where specifying thousands of singleton kern pairs could silently overflow offsets, and makeotf would build a bad font without any warning. (reported by Adam Twardoch)
• [makeotf] Relative file paths can now be used even if the current directory is not the source font directory. Project files can now be saved to directories other than the source font directory. Note that paths stored in project file are relative to the project file's directory. (reported by Andreas Seidel)
• [makeotf/spot] Added support for Unicode Variation Sequences (UVSes). See MakeOTF User's Guide and Unicode Technical Standard #37
• [spot] Fixed bug where contents of 'size' GPOS feature would be printed for all dump levels.
• [spot] Fixed failure to process 'post' table format 4.0. which occurs in some Apple TT fonts, such as Osaka.dfont
• Updated Adobe-Japan-1 CMAP files for building CID fonts.

2.0.26 (released 2007-05-05)

• Added featurefile.plist for BBedit. Install this in the location shown at the top of the file; it enables code coloring for FEA syntax. The file is in FDK/Tools/SharedData
• Added MSFontValidatorIssues.html to FDK/Technical Documentation. It lists the error messages from the MS FontValidator tool that can be ignored for OpenType/CFF fonts.
• [FontLab macros] Added InstanceGenerator. Another script for making instances from an MM VFB font. It's simpler than MakeInstances macro.
• [FontLab macros] Removed debug statement in Set Start Points which blocked processing more than 50 glyphs. (reported by George Ryan)
• [FontLab macros] Added explanation of CheckOutlines errors to help dialog.
• [checkOutlines] Added option '-he' to print explanation of error messages.
• [compareFamily] Added error if the font's CFF table contains a Type 2 seac operator. The CFF spec does not support this operator. Some very old tools allow this to happen.
• [makeotf] Fixed a bug in decomposing glyphs that are defined as composite glyphs in a Type 1 source font. This bug caused the base component to be shifted when then left side bearing of the composite glyph differs from that of the base glyph. This could be consequential, as FontLab has an option to not decompose composite glyphs when generating a Type 1 font.
• [makeotf] Fixed a bug in recognizing the "Korea1" order when trying to pick a default Mac cmap script ID from a CID-keyed font's ROS (Registry-Order-Supplement) field.
• [tx] Fixed a bug in decomposing pretty much all composite glyphs from Type 1 and CFF source fonts. It happened only when a Type 1 or CFF font was being subset, i.e. converted into a font with fewer glyphs. tx now has the option '+Z' to force this to occur.

2.0.25 (released 2007-03-30)

• [autohint] Added a new option to allow extending the list of glyph names for which autohint will try to make counter hints.
• [autohint] Fixed bug where Type 2 operator stack limit could be exceeded when optimizing Type 2 charstrings during conversion from bez format.
• [autohint] Fixed bug in setting OtherBlues alignment zone values.
• [FontLab macros] The Autohint macro behaves quite differently when adding 'flex' hints is turned off; it makes more hint substitutions, since these are not allowed within the segment of the outline that contributes the 'flex' stem. Turned it on, so that hint results will be the same as the command-line tool. This does not affect the outline data.
• [checkOutlines] Fixed bug that prevented the reporting of two successive points with the same coordinates. The code to convert from the source outline data to bez format was suppressing zero-length line segments, so the checkOutlines module never experienced the problem.
• [compareFamily] Added new options '-st n1,n2..' and '-ft n1,n2..' to allow executing only specific tests.
• [compareFamily] Fixed test "Warn if a style-linked family group does not have FamilyBlues". When reporting the error that FamilyBlues differ in a style-linked family group (where at least one font does have real FamilyBlues), use BlueValues as implied FamilyBlues when the latter attribute is missing from a font. Same for FamilyOtherBlues.
• [compareFamily] Warn about zones outside of font's BBox only if the entire zone is outside of the BBox, not just one edge, and warn only for BlueValue zones, not FamilyBlueValue zones.
• [compareFamily] Fixed fsType check. Complain if fsType is not 8 only for Adobe fonts, determined by checking if the name table trademark string is empty or contains "Adobe".
• [compareFamily] Fixed Single Face Test 3 to compare the CFF Full Name with the name table Preferred Full Name (ID 18) rather than the Full Name (ID 4).
• [compareFamily] Fixed bug where it failed with CID fonts, because it referenced the "Private" dict attribute of the font's topDict, which does not exist in CID fonts.
• [compareFamily] Fixed 'size' test to support the format that indicates only intended design size, where no range is supplied.
• [compareFamily] Fixed ligature width check to also check that left and right side bearings match those of the left and right components, and to use the 'liga' feature to identify ligatures and their components, instead of heuristics based on glyph names.
• [makeotf] Disallowed negative values in the feature file for the OS/2 table winAscent and winDescent fields.
• [makeotf] Fixed a bug where a lookup excluded with the exclude_dflt keyword was nevertheless included if the script/language was specified with a languagesystem statement.
• [makeotf] Fixed issue on Windows where a user would see a debug assert dialog when the OS/2 vendorID was not specified in the feature file, and the Copyright string contained an 8-bit ASCII character, like the 'copyright' character.
• [makeotf] Fixed issue on Windows where name ID 17 would be garbage if no FontMenuNameDB was supplied, and the PostScript name did not contain a hyphen.
• [makeotf] Added warning for Mac OSX pre 10.5 compatibility: total size of glyphs names plus 2 bytes padding per glyph must be less than 32K, or OSX will crash.
• [makeotf] Fixed crash that occurred if the feature file did not have a languagesystem statement.
• [makeotf] Fixed bug in subroutinizer which allowed a subroutine stack depth of up to 10, but the Type 1 and Type 2 specs allow only 9. This caused most rasterizers to declare the font invalid.
• [makeotf] Removed '-cv' option; CJK vertical CMaps have not been supported since FDK 1.6.
• [spot] Added support for low-level and feature file style text dumps of GPOS Attachment formats 3, 4, 5 and 6.
• [spot] Added dump of lookup flag value to the feature-file style report.

• [spot] Fixed bug in GSUB lookup 5, causing crash in dumping trado.ttf.
• [spot] Fixed bug in level 7 (feature-file syntax) dump of GPOS table; was omitting the value record for extension lookup types.
• [spot] Fixed crash on Windows when proofing contextual substitution statements.
• [spot] Made Windows version behave like Mac when proofing: PostScript file data is always sent to standard output, and must be re-directed to a file.
• [spot] Improved documentation of proofing output and '-P' option.
• [spot] Fixed DSIG table reporting of TTC fonts with the version 2 TTC header, even if the header reports it is version 1, like meiryo.ttc.

• [spot] Fixed origin offset of bounding box for TTF fonts.
• [spot] Fixed crash in proofing TTF fonts when the last glyph is non-marking, like trado.ttf in LongHorn.

2.0.24 (released 2006-11-06) — Public release of FDK 2.0

• [autohint/checkOutlines/ProofPDF] Fixed glyph name handling to avoid stack dump when glyph is not in font. Added support for CID values that are not zero-padded to 5 hex digits.
• [autohint] Fixed bug where edge hints would be generated rather than regular hints across the baseline, when there were fewer than 8 pairs of BlueValues.
• [checkOutlines] Fixed bug where it would not report an overlap if there were an even number of overlapping contours.
• [compareFamily] Fixed Italic angle Single Test 12 to look at the middle third of the test glyph stems, rather than the top and bottom of the glyph bounding box, when guessing the font's italic angle.
• [compareFamily] Fixed Single Test 15 to allow a difference of 1 unit in the font BBox, to allow for rounding differences.
• [compareFamily] Fixed Single Test 26 to identify uXXXX names as valid Unicode names; had bug in the regular expression that required 5 digits.
• [compareFamily] Fixed Single Test 22 to treat glyphs in the combining mark Unicode range u3000-u036F range as accent glyphs; require that they have the same width as the base glyph.
• [compareFamily] Changed report from Error to Warning for check that only the first four Panose values are non-zero.
• [compareFamily] Fixed bug that caused a stack dump in Single Test 16 and 22.
• [compareFamily] Added tests for Mac OSX pre 10.4 compatibility: no charstring is < 32K, total size of glyphs names plus padding is less than 32K.
• [compareFamily] Added test that known shipping font does not have OS/2 table version 4, and that new fonts do.
• [compareFamily] Fixed Single Test 11: allow BASE offset to differ from calculated offset by up to 10 design units before it complains.
• [compareFamily/makeotf] Fixed failure when tools path contains a space.
• [kernCheck] New tool; looks for kern GPOS rules that conflict, and also looks for glyph pairs that overlap.
• [kernCheck] Added option to allow running only the check of GPOS subtables for kerning rules that mask each other.
• [makeotf] Fixed '-adds' option.
• [makeotf] Added new option '-fi' to specify path to fontinfo file.
• [makeotf] Added new option '-rev' to increment the fontRevision field.
• [makeotf] If the (cid)fontinfo file contains the keyword/value for FSType, will check that the value is the same as the OS/2 fsType field in the final OTF font. This has to do with historic Adobe CJK font development practices.
• [makeotf] Added support for setting some of the Plane 1+ bits in the OS/2 ulUnicodeRange fields.
• [mergeFonts] Will now apply to the output font the values for the fields Weight and XUID, from the cidfontinfo file.

• [stemHist] When requiring that reports not already exist, don't delete older stem reports when asking for new alignment zone reports, and vice-versa.
• [setsnap.pl] New tool to pick standard stem hint values. This Perl script takes in the report from stemHist, and recommends a set of values to use for the Type 1 font standard stem arrays. This is not as good as choosing the most relevant values yourself, but better than not providing any values.
• In Overview.html, added warning about 'languagesystem Dflt dflt' and FDK 1.6 feature files.
• In MakeOTFUserGuide.pdf, expanded discussion of fontinfo file, updated documentation of OS/2 v4 table bits with Adobe's practices for the next library release.

• Added two new tech notes on using rotateFont and mergeFonts.

2.0.22 (released 2006-09-12)

• [compareFamily] Single Test 3 now also checks that Mac name ID 4 starts with Preferred Family name, and is the same as the CFF table Full Name.
• [compareFamily] Added test for existence and validation of BASE table in Single Test 11.
• [compareFamily] Fixed bug where failed when reporting font BBox error.
• [compareFamily] Added test that some specific glyph names were not changed from previous version of font, in Single Test 26.

• [compareFamily] Added "Single Face Test 28: Check font OS/2 codepages for a common set of code page bits". Checks OS/2 ulCodePageRange and ulUnicodeRange blocks against the default makeotf heuristics.
• [compareFamily] Added in Single Test 12 a rough calculation of the italic angle. Warns if this is more than 3 degrees different than the post table Italic angle value.

• [compareFamily] Added "Family Test 16: Check that for all faces in a preferred family group, the width of any glyph is not more than 3 times the width of the same glyph in any other face".
• [compareFamily] Fixed Family Test 3 to be more efficient.
• [makeotf/makeotfexe] Added a new option '-maxs <integer>' to limit the number of subroutines generated by subroutinization. Used only when building test fonts to explore possible errors in processing the subroutines.
• [makeotf/makeotfexe] Allow working names to be longer than 31 characters; warn but don't quit, if final names are longer than 31 characters.

2.0.21 (released 2006-08-31)

• [makeotf] Fixed bug where 'size' feature was built incorrectly when it was the only GPOS feature in the font.
• [spot] Improved error messages for 'size' feature problems.
• [compareFamily] Added dependency on environment variables: CF_DEFAULT_URL should be set to the foundry's URL; it's compared with name ID 11. CF_DEFAULT_FOUNDRY_CODE should be set to the foundry's 4-letter vendor code; it's compared with OS/2 table achVendID field.
• [compareFamily] Check that CFF PostScript name is the same as Mac and Windows name table name ID 6.
• [compareFamily] Check that named IDs 9 and 11 (designer name and foundry URL) exist.
• [compareFamily] Extended Single Test 4 to verify that version string is in correct format '(Version|OTF) n.nnn'.
• [compareFamily] Improved Panose test to check that values are not all 0, and that the CFF font dict 'isFixedPitch' field matches the Panose monospace value.
• [compareFamily] Added check to confirm the presence of Unicode cmap sub table.
• [compareFamily] Added check to confirm that latn/dflt and DFLT/dflt script/languages are present, if there are any GPOS or GSUB rules. Also checks that script and language tags are in registered lists, and that all faces have the same set of language and script tags, and feature list under each language and script pair.
• [compareFamily] Added check to confirm that all faces in the family have the same OS/2 table fsType embedding permission values.
• [compareFamily] Added check to confirm that if font has Bold style bit, the CFF forceBold flag is on. Also vice-versa, if the font weight is less than 700.
• [compareFamily] Added check to confirm that the font does not have a UniqueID or XUID, if it's not CID-keyed.
• [compareFamily] Added glyph name checks: OS/2 default char is .notdef, and that there are NULL and CR glyphs in TrueType fonts, and that names conform to the current Adobe Glyph Dictionary. Note that latest practice is to use 'uni' names for final names for all the 'afii' glyphs.
• [compareFamily] Fixed family BlueValues tests to compare within compatible family name groups.
• [compareFamily] Changed Family Test 2 to check that all name IDs except 16, 17, 18, are all present with the same language/script values within all faces of a preferred family.
• [compareFamily] Changed Single Test 3, which didn't do at all what it described.
• [FontLab macros] Fixed bug introduced when changing modules shared with command-line scripts in build 19.

2.0.20 (released 2006-08-14)

• [ProofPDF] Fixed bug in waterfallplot mode, where Acrobat would report the output PDF file as being damaged.
• [makeotf] Fixed bug that prevented building CID fonts in release mode, introduced in build 19.

2.0.19 (released 2006-08-04)

• [compareFamily] Added Family Test 13 to report error if two fonts in the same preferred family have the same OS/2 weight, width and Italic settings, and the OS/2 version is greater than 3. Also reports an error if the fsSelection field bit 8 "WEIGHT_WIDTH_SLOPE_ONLY" is set differently across faces of the same preferred family name group.

• [compareFamily] Fixed Family Test 12 to not fail when the font has a script/language with no DefaultLangSys entry.

• [makeotf] If a font file with the requested output file name already exists, will delete it before running makeotfexe, so can tell if it failed.

• [makeotf] Will now set the new 'fsSlection' bits if the following key/value pairs are in the 'fontinfo' file:

    PreferOS/2TypoMetrics 1
    IsOS/2WidthWeigthSlopeOnly 1
    IsOS/2OBLIQUE 1
  

• [digiplot] Added new option to specify the font baseline, so the baseline can be set correctly when proofing a font file without a BASE table.

• [digiplot] Allowed using a CID layout file to supply meta info when proofing name-keyed fonts.

2.0.17 (released 2006-05-15)

• Fixed multiple tools to allow installing the FDK on Windows on a path containing spaces.

• [autohint] Added option to suppress hint substitution.

• [autohint] Fixed help and message to refer to 'autohint' tool name, rather than to the AC script file name.

• [autohint] Added option to allow hinting fonts without StdHW or StdVW entries in the font Private font-dictionary.

• [checkOutlines] Fixed writing out the changes when fixing outlines.

• [checkOutlines] Fixed bug that mangled outlines when three alternating perpendicular lines or vh/hv/vv/hh curveto's followed each other.

• [checkOutlines] Will now write report to a log file as well as to screen. Added option to set log file path, and added numeric suffix to name so as to avoid overwriting existing log files.

• [compareFamily] Fixed issue that happened when looking through the directory for font files, when encountering a file for which the user did not have read permission.

• [compareFamily] Added Single Test 24: check that 'size' feature Design Size is within the design range specified for the font.

• [ProofPDF] Added showfont command to show how to customize a command file to produce a different page layout.

• [ProofPDF] Fixed so fonts with em-square other then 1000 will work.

• [makeotf] Fixed MakeOTF to survive being given a font path with spaces.

• [makeotf] Fixed '-S' and '-r' options.

• [makeotf] Added new option '-osv <number>' to allow setting the OS/2 table version number.

• [makeotf] Added new option '-osbOn <number>' to set arbitrary bitfields in OS/2 table 'fsSelection' to on. May be repeated more than once to set more than one bit.

• [makeotf] Added new option '-osbOff <number>' to set arbitrary bitfields in OS/2 table 'fsSelection' to off. May be repeated more than once to unset more than one bit.

• [makeotf] If neither '-b' nor '-i' options are used, check for a file 'fontinfo' in the same directory as the source font file, and set the style bits if these key/values are found:

    IsBoldStyle true
    IsItalicStyle true
  

• [FontLab macros] Built the autohint and checkOutline libraries (PyAC and focusdll) linked with Python2.3 so they work with FontLab 5.

• [mergeFonts] Added option to copy only font metrics from first source font.

• [mergeFonts] Allow empty lines and "#" comment lines in glyph alias and in cidfontinfo files.

• [rotateFont] Fixed bug where it did not allow negative numbers.

• [rotateFont] Allow empty lines and "#" comment lines in rotation info file

• [sfntedit] Fixed so that it will not leave the temp file behind on a fatal error, nor quit because one already exists.

• [spot] Fixed order of backtrack glyphs in dump of chaining contextual sub and pos statements. Now assumes that these are built in the correct order.

• Added two new tools, type1 and detype1, that compile/decompile a Type 1 font from/to a plain text representation.

2.0.5 (released 2006-02-14)

• [compareFamily] Updated test for allowable weights in style-linked faces to reflect the current behavior of Windows XP.
• [compareFamily] Added check for OpenType/CFF: Windows name table ID 4 (Full Name) is the same as the PostScript name.
• [compareFamily] Added report on sets of features in different languagesystems, and an error message if they are not the same in all faces of the font.
• [compareFamily] Fixed incorrect message about real error when menu names are not correctly built.
• [compareFamily] Fixed test for improbable FontBBOX to use em-square rather than assume 1000 em.
• [compareFamily] Added warning if widths of ligatures are not larger than the width of the first glyph.
• [compareFamily] Added warning if accented glyphs have a width different than their base glyph.
• [compareFamily] Added error message if two faces in the same family have the same OS/2 width and weight class and italic style setting, and are not optical size variants. Optical size check is crude: the Adobe standard optical size names (Caption, Capt, Disp, Ds, Subh, Six) are removed from the PS font names and then compared; if the PS names are the same, then they are assumed to be optical size variants.
• [compareFamily] Added check that no hint is outside the FontBBox, for CJK fonts only.
• [spot/otfproof] Added "Korean" to list of tags for OS/2 codepage range.
• [spot/otfproof] Fixed dump of 'size' feature to support correct and old versions

• [spot/otfproof] Added warnings that only low-level dump of other contextual lookups is supported.
• [makeotf] Program is now a stand-alone C executable.
• [makeotf] Removed option to write contextual positioning rules in the old incorrect format.
• [makeotf] MakeOTF no longer assigns Unicode Private Use Area values to glyphs for which it cannot identify. To use PUAs, explicitly assign them in the GlyphOrderAndAlias file.
• [makeotf] Fixed bug in name table name ID "Version": if version decimal value is x.000, then the value in the Version name ID string was x.001.
• [makeotf] Fixed bug in handling of DFLT language script: it's now possible to use this tag.
• [makeotf] Fixed feature file parsing bug where 'dflt' lookups in one feature were applied to the following feature if the following feature started with a language statement other than 'dflt'.
• [makeotf] Fixed serious bug where wrong width is calculated for glyphs where the CFF font Type 2 charstring for the glyph starts with a width value. This is then followed by the value pairs for the coordinates for the vertical hint, and then these are followed by a hint mask or control mask operator. The bug was that when MakeOTF reads in the charstring in order to derive the hmtx width, it discards the data before the control mask operator, leading the parser to use the CFF default width for the glyph.
• [makeotf] vhea.caretSlopeRise and vhea.caretSlopeRun is now set to 0 and 1 respectively, rather than the opposite.
• [makeotf] The OS/2 table 'fsType' field is now set to the feature file override. If not supplied, then the value of the environment variable FDK_FSTYPE. If not set then 4 (Preview & Print embedding).
• [makeotf] Added support for contextual chaining positioning of base glyphs; mark and anchors not yet supported.
• [makeotf] Fixed bug in 'size' feature: the feature param offset is now set to the offset from the start of the feature table, not from from the start of the FeatureList table.
• [makeotf] Allowed 'size' feature point sizes to be specified as decimal points, as well as in integer decipoints.
• [makeotf] OS/2 table version is now set to 3.
• [makeotf] Added OS/2 overrides for winAscent and winDescent.
• [makeotf] Added hhea overrides for Ascender/Descender/LineGap.
• [makeotf] Set OS/2 Unicode coverage bits only if the font has a reasonable number of glyphs in the Unicode block; it was setting the bits if the font had even one glyph in the block.
• [makeotf] The "Macintosh" codepage bit in the OS/2 codePageRange fields is now set by default.
• [FEA spec] Fixed incorrect range example in section 2.g.ii. Named glyph classes
• [FEA spec] Changed rule to allow lookup definitions outside of feature definitions in FDK 2.0.
• [FEA spec] Fixed incorrect uses of 'DFLT' rather than 'dflt' for a language tag.

1.6.8139 (released 2005-08-30)

• [OTFProof] Fixed error in dumping GSUB table: GSUB lookup 5, context lookup assumed that there were both a lookahead and a backtrack sequence.
• Updated SING META table tags to latest set.

1.6.7974 (released 2004-08-30)

• [makeotf] Fixed rule in building CJK font. When looking for Adobe CMap files, will no longer use a hardcoded max supplement value when building paths to try.

1.6.7393 (released 2004-01-14)

• [compareFamily] Fix stack dump when family has no BlueValues (reported by House Industries).
• [compareFamily] Fix stack dump when CFF-CID font has glyph with no subr calls.
• [OTFProof] Corrected error in last release, where spaces between ligature match string names were omitted.
• [FontLab macros] Added scripts for testing if the joins in a connecting script font design are good.
• [OTFProof] Fixed crash on proofing or dumping feature file syntax for GSUB lookup 5, context lookup. Also fixed rule-generating logic: results were previously wrong for proof and for feature-file syntax formats. Text dump has always been correct.
• [OTFProof] Fixed crash when dumping cmap subtables that reference virtual GIDs not in the font.
• [OTFProof] Fixed crash on dumping GSUB lookup type 6 chaining context subtable format 2. This has never worked before.
• [OTFProof] Added demo for SING glyphlet tables, SING and META.
• [FontLab macros] Added scripts for reading and writing an external composites definition text file.
• [FontLab macros] Added scripts for working with MM fonts.

1.6.6864 (released 2003-10-08)

• [OTFProof] Fixed crash after dumping contents of ttc fonts (bug introduced in version 6792).
• [OTFProof] Fixed cmap subtable 4 and 2 dumps. Cmap subtable 2 could show encoding values for single byte codes which were really the first byte of two byte character codes. In Format 4, idDelta values were not being added when the glyphindex was derived from the glyph index array. These show issues show up in some TTF CJKV fonts.

1.6.6792 (released 2003-09-24)

• [OTFProof] Fixed crash when proofing fonts with many glyphs.
• [OTFProof] Restored "skipping lookup because already seen in script/language/feature" messages to proof file, which was lost in version 6604.
• [OTFProof] Added ability to proof resource fork sfnt fonts from Mac OSX command line. It's still necessary to use the SplitForks tool to make a data-fork only resource file, but spot/otfproof can now navigate in the resulting AppleDouble formatted resource file.
• [OTFProof] Added support for a text dump of the GDEF table.
• [OTFProof] Changed title in 'size' feature dump from Common Characters to name table name ID for common Subfamily name for size group.

1.6.6629

• [OTFProof] Fixed bug in dumping KERN table from Mac sfnt-wrapped resource fork Type 1 MM font.
• [OTFProof] Changed the AFM-format dump of kern pairs to list all kern pairs for each language/script combination in separate blocks, and to eliminate all class kern pairs that are masked by a singleton kern pair. The temp buffer file path is now taken from the system C library function tmpnam(), and is not necessarily in the current directory.

1.6.6568

• [OTFProof] Fixed command-line tool to write proof files in same location as font, and with font-name prefix, when not auto-spooled for printing.
• [OTFProof] Fixed bug in UI version where proofing GSUB features and then GPOS features would cause the GPOS feature proof files to be empty.
• [makeotf] Fixed heuristics for picking OS/2 weight/width so that a font name containing ultracondensed would trigger only setting the width, and not the weight as well.
• Updated Mac OS project files to CodeWarrior 8.

1.6.6564

• [OTFProof] When dumping data from TTF fonts, now add @<gid> to all glyph names. This is because the rules for deriving names can lead to two glyphs being given the same name.
• [OTFProof] Fixed bug in proofing GPOS class kern pairs: was generating bogus kern pairs and duplicate kern pairs when the coverage format was type 2. Affects proof file only, not AFM or feature-format dump.
• Fixed memory overwrite bug encountered by Goichi and cleaned up various memory leaks in the process.
• [compareFamily] Added report on whether a face contains known std charset. Stub implementation - still need list of std charsets.
• [AFM2Feat] Developed tool to convert an AFM file to a file with kern feature pos rules.

1.6.6148

• Rebuilt all libraries for v1.6 release 3/10/2003.

1.6.6048

• Updated FinishInstall.py to reflect Python 2.2 requirements.
• Picked up last MakeOTF.pdf editing changes.
• Fixed bug in GOADB.
• Updated CID font data in example fonts.
• Updated FDK release notes and installation instructions.
• Updated to use the GlyphOrderAndAliasDB file developed while converting the Adobe Type Library. Maps all the old glyph names to AGL compatible names.

1.6.6020

• [OTFProof] Fixed crash in handling of VORG with no entries. (Vantive 574752)
• [MakeOTF] Updated documentation: added a description of how all three columns of the GlyphOrderAndAliasDB file are used; added a new section on the key-value pairs of the font project file; updated the description of the FontMenuNameDB file entries; added minor clarifications throughout.
• Updated digital_signature_guide.htm to match current Verisign website.
• [Example fonts] Changed the incorrect language keyword TUR to TRK.
• [Example fonts] Removed the many key/value pairs in the fontinfo files that are not used by MakeOTF.
• [OTFProof/spot] Fixed 3-column handling of GOAADB. (Vantive 569681)

1.6.5959

• [MakeOTF] Suppressed the "repeat hint substitution discarded" message from the source file parsing library. These are so common that they obscure more useful messages.

• [MakeOTF] Set as default the option to build chaining contextual substitution rules with the incorrect format used by InDesign 2.0 and earlier.

• [MakeOTF] If the option above is set, then MakeOTF will write a name ID (1,0,0,5 - "Version") which will contain the text string which triggers special case code in future Adobe apps so that it will process the chaining contextual substitution rules as they were intended. If this option is NOT set, the name ID 5 will be written so as to not trigger this special case code. The special case treats specially any font where the name table name ID (1,0,0,5) exists and either matches,

    "OTF[^;]+;PS[^;]+;Core 1\.0\.[23][0-9].*"
  

  (example: "OTF 1.006;PS 1.004;Core 1.0.35") or contains,

    "Core[^;]*;makeotf\.lib"
  

  (example: "Core 1.0.38;makeotf.lib1.5.4898") or just,

    "Core;makeotf.lib"
  

• [MakeOTF] Turn off by default the option to force the .notdef glyph in the output OTF font be an crossed rectangle with an advance width of 500.

• [MakeOTF] Added rule to force the OS/2 WeightClass to always be at least 250. Shows error message if set or calculated WeightClass was less than this.

• [MakeOTF] Added test that FSType is set the same in the feature file as in source CID font files.

• [OTFProof] Page layout for CJKV font vertical layout: now writes the vertical columns right to left.

• [OTFProof] When writing vertical features, now shows the advance width sign as negative.

• [OTFProof] When making PostScript proof file, now writes DSC tags with correct header and page info.

• Added Unicode and Glyph Name documentation to the FDK Technical Documentation directory, to allow access to this info under the FDK license.

1.6.4908

• [MakeOTF/FEA syntax] Added new vmtx table overrides, to allow setting vertical metrics for pre-rotated proportional glyphs that are specifically designed and are not simply rotated forms of proportional glyphs.
• [MakeOTF/FEA syntax] Added new OS/2 overrides to set the Unicode and Windows codepage range fields: UnicodeRange CodePageRange.
• [MakeOTF/FEA syntax] Updated language keywords to be consistent with OpenType spec, i.e using dflt instead of DFLT. Expanded section explaining use of language and script default keywords. Old keywords still work, but cause a warning to be emitted.
• [FEA syntax] Expanded explanation of kern class pairs and subtable breaks.
• [MakeOTF] Updated the search rules for CID font CMap files to support Adobe-Japan2-0, and to look first for UTF-32 CMAP files.

1.5.4987

• Release to Adobe website Sept 2002.

1.5.4908

• [MakeOTF] Changed the name table version string to match OT spec 1.4.
• [CompareFamily] Made it really work with Sept 10th 2002 release of Just van Rossum's FontTools library.

1.5.4492

• [MakeOTF] (hotlib 1.0.35) Fixed the error in processing GSUB contextual chaining substitution format 3. This was originally done according to the OpenType spec 1.4, which is in error by the established implementation of VOLT and Uniscribe. Added option '-fc' to cause the library to use the incorrect implementation, according to OT spec v1.4. By default, MakeOTF builds the correct contextual format per spec v1.5.
• [MakeOTF] (hotlib 1.0.35) Fixed Unicode cmap bug in assigning the OS/2 table field usLastCharIndex. This is supposed to be the highest Unicode value in the BMP-16 cmap tables. The problem was in the logic by which alternates of supplemental plane glyph names were being assigned an EUS code, but not added to the BMP-16 Unicode cmap tables, e.g. u1D269.alt. When one of these alternates was assigned an EUS value, the usLastCharIndex was getting bumped even though the glyph was not being added to the BMP-16 cmap tables. Fixed by not incrementing usLastCharIndex in this case.
• [MakeOTF] Fixed bug in applying client-supplied Unicode override values. These were omitted if the glyph names in the font were different than the final glyph names, as can happen when the client uses the getFinalGlyphName call back to supply a glyph production name which is different than the final glyph name.
• [OTFProof] Fixed crash when proofing liga feature in CID font. Also fixed crash when proofing charstring with only one operand, e.g h/r/vmoveto.
• [CompareFamily] Updated to use the latest version of Just van Rossum's FontTools library, added support for TrueType fonts. Now requires Python 2.2.
• [CompareFamily] Added family test 11: verify that for base font in style-linked group, Mac and Windows menu names are the same, and that for other fonts in the style linked group, the Mac and Windows menu names differ.

1.5.4099

• External release of FDK 1.5 on Adobe website.

1.5.3849

• [CompareFamily] Fixed tabular glyph and isFixedPitch test so that they are now useful - used to generate far too many false errors.
• [MakeOTF] Fixed bug in setting Panose values from a feature file override. If any value in the Panose value string is 0, all subsequent values were also set to 0.

• [spot] Added the option to select which feature to dump in GPOS or GSUB=7 dumps.
• [OTFProof] Added support of TT instructions in compound glyphs.
• [CompareFamily] Fixed incorrect unwrapping T2 charstring subroutines. All previous reports on whether glyphs were hinted should be doubted.

• [MakeOTF] Added an option to allow removing deprecated Type 1 operands from output font (e.g. seac and dotsection).

• [MakeOTF] Added an option to allow adding synthesized glyphs to fonts, leveraging a built-in sans and serif multiple master substitution font. The source font must contain a 'zero' and a capital 'O'. The glyphs that can be synthesized are:

1.4.583

• Began tracking files by Perforce changelist label, from the Perforce source code management system.
• Updated compilers to Mac/CodeWarrior 6 Pro, Windows Visual C++ 6.0.
• Re-organized build directories to have mac/win/sun4 subdirectories.
• Re-organized shared include files to all be under /Programs/api, with non-conflicting names.
• [Example fonts] Updated MinionPro-Capt: now has correct frac and size features.
• [Example fonts] Added KozMinPro to samples.
• [MakeOTF] Fixed bug where fontinfo keyword IsStyleBold was ignored for CID fonts.
• [MakeOTF] Fixed Mac build project to load debug and release libraries by different names.
• [MakeOTF] Added feature file support for the "languagesystem" statement. Note that this entailed removing support for script, language, and named lookup statements in the size feature, and removing support for script and language statements in the aalt feature. See feature file spec for details.
• [MakeOTF] More descriptive wording in offset overflow error messages. Feature file error handling improved: multiple error messages are emitted before failing if possible, instead of just one; final glyph name as well as glyph alias (if applicable) reported if not found in font.
• [MakeOTF] Changed the 14 Corporate Use subarea Unicode values for Zapf Dingbats to the proposed UVs in anticipation of their being incorporated into the Unicode standard.
• [MakeOTF] Added FontWorks ('FWKS') to vendor ID list.
• [MakeOTF] Increased the maximum number of named lookups allowed to 8192.
• [MakeOTF] Now makes kern and vert features from kern data passed in by clients and from V CMap (respectively) only when the HOT_CONVERSION bit is set. (Previously, these features were made from the sources mentioned above if they weren't already defined in a feature file.)
• [MakeOTF] Fixed an obscure bug in OS/2.ulUnicodeRange computation: if the largest UV in the font were not in any Unicode range recognized by hotlib then it was counted as being in the next recognized Unicode range after the UV. (No known fonts are affected by this.)
• [MakeOTF] Forced the OS/2 codepage range bits for Chinese to either Simplified or Traditional, based on the Mac cmap script, if it is defined as either Simplified or Traditional, and will fall back to the heuristics if the script is undefined. If the mac.script is something other than a Chinese script, then the OS/2 codepage range bits for Chinese will not be set.
• [OTFCompare] The Python sys.path variable must now contain the path to the directory containing the OTFProof library (usually FDK/Tools/Programs/otfproof/exe). This replaces the hardcoded path reference in the OTFCompare.py script. On all platforms, this is done by adding the file "otfproof.pth", containing the path, to the Python installation.
• [OTFCompare] Fixed a bug that was causing tables smaller than 16 bytes to be reported as different
• [OTFProof] Added new proofing mode to CFF_ to print one glyph per page.
• [OTFProof] Added new proofing option to suppress file-specific header info to facilitate diff-ing of multiple proofs.
• [OTFProof] Added alphabetical sorting of AFM-style dump.
• [OTFProof] Fixed bug causing GPOS/GSUB features with digits in their names to not appear in the proofing list.
• [OTFProof] Added support for glyphsize option in CFF_ dumps.
• [OTFProof] Fixed conflicting include file names; must now specify include paths in project file.
• [OTFProof] Reduced some of the recursion in the subroutinization code to reduce stack space requirements.
• [OTFProof] Fixed support for included feature files in parent folder on the Mac.

1.3.2 (2000-10-24)

• [OTFProof] Fixed bug where would report error opening Mac TTF suitcase font, because data fork was of size 0.
• [OTFProof] Fixed bug where feature tags containing numbers were filtered out of the feature list for proofing.
• [OTFProof] Fixed bug where baseline was shown incorrectly for CJK fonts with baselines other than 120.
• [OTFProof] Fixed bug where y-placement changes were not shown correctly in vertical writing mode proofs.

1.3.1 (2000-08-15)

• [MakeOTF] Fixed problem with heuristics for OS/2 codepage range settings, for Chinese Simplified vs Traditional.

• [MakeOTF] Added macro to define MakeOTF version number.

• [MakeOTF] updated makeotflib help/usage messages: shown when args are incorrectly formatted.

• [makeotf] (makeotf/exe/makeotfutils.py)

  • added fontinfo list entry for "Language".
  • added 'parameter' variable entry for same.
  • increased num values to from 34 to 35.
  • changed initialization of 'parameter' so can more easily figure out which index matches which fontinfo field.

• [makeotf] (makeotf/exe/makeotf.py)

  • updated version numbers to 1.3.1.
  • added '-cs' and '-cl' options to help.
  • added processing of Language field, to set script and language IDs with '-cs' and '-cl' options.

• [makeotf] (makeotf/source/main.c)

  • added macro to define MakeOTF version number, used in help message, and in client name string for name id 5 "Version".
  • added mac_script and mac_language fields to global static 'convert' structure.
  • added processing of '-cs' and '-cl' arguments to parse_args().
  • added mac_script and mac_language arguments to call to cbconvert().
  • updated print_usage to match that of makeotf.py.
  • updated the ReadFontInfo() to process new Language field.

• [makeotf] (makeotf/source/cb.c)

  • moved initialization (as type unknown) of mac.encoding, mac.script and mac.language from cbconvert to cbnew().
  • added setting of mac.script and mac.language to cbconvert(), from arguments.
  • added mac_script and mac_language arguments to call to cbconvert().

• [makeotf] (source/includes/cb.h)

  • added mac_script and mac_language arguments to call to cbconvert().

• [hotconvlib] (coretype/source/map.c)

  • changed logic for setting OS/2 codepage range to set code page to Simplified or Traditional Chinese based on mac.script setting; fallback on heuristics only if mac.script is not set.
