3.5.0

This is a major update and reflects a large number of changes added into node-mapnik due to update of the Mapbox Vector Tile Specification. As part of this the mapnik-vector-tile library was updated to 1.0.0. Therefore, a large number of interfaces changes have taken place around the mapnik.VectorTile object.

It is important to know that the concept of width and height have been removed from mapnik.VectorTile objects. This is replaced by the concept of tileSize. While width and height were based on the concept of an Image size created from a vector tile, tileSize is directly related to the extent as defined in the Layer of a vector tile. For understanding what the Layer and extent is please see the Vector Tile Specification. This also changed the buffer_size arguments that were commonly used in many Vector Tile methods, which was also based on the Image size. The vector tile object now contains a bufferSize which represents the buffer added to the layer extent in a tile.

Internally, all methods now depend on V2 tiles, however, any V1 tiles that are loaded into a mapnik.VectorTile object will automatically be updated.

Summary of changes:

• mapnik.VectorTile.addData now verifies buffers validity and internally updates v1 tiles to v2
• mapnik.VectorTile.addDataSync now verifies buffers validity and internally updates v1 tiles to v2
• mapnik.VectorTile.setData now verifies buffers validity and internally updates v1 tiles to v2
• mapnik.VectorTile.setDataSync now verifies buffers validity and internally updates v1 tiles to v2
• mapnik.VectorTile.addImage now takes a mapnik.Image object rather then a buffer, it also takes optional arguments image_scaling and image_format.
• mapnik.VectorTile.addImageBuffer replaces the old functionality of of mapnik.VectorTile.addImage
• Added mapnik.VectorTile.addImageSync and made mapnik.VectorTile.addImage accept a callback.
• Added mapnik.VectorTile.addImageBufferSync and made mapnik.VectorTile.addImageBuffer accept a callback.
• mapnik.VectorTile.height() method is removed
• mapnik.VectorTile.width() method is removed
• mapnik.VectorTile.parse() method is removed
• mapnik.VectorTile.IsSolid() method is removed
• mapnik.shutdown() is removed
• Removed the dependency on libprotobuf library
• Lowered memory requirements for vector tile creation and vector tile operations.
• Duplicate layer names in mapnik.VectorTile objects are no longer permitted.
• Added new mapnik.VectorTile.extent() method which returns the bounding box of a tile in EPSG:3857
• Added new mapnik.VectorTile.bufferedExtent() method which returns the bounding box including buffer of a tile in EPSG:3857
• Added new mapnik.VectorTile.emptyLayers() method which returns the name of layers which were not added to a tile during any tile rendering operation.
• Added new mapnik.VectorTile.paintedLayers() method which returns the name of layers which were considered painted during rendering or layers that contain data.
• Added new mapnik.VetorTile.tileSize property.
• Added new mapnik.VetorTile.bufferSize property.
• Updated many of the default configuration options on mapnik.VectorTile class methods
• Removed the concept of path_multiplier from the code entirely.
• Added optional arguments of tile_size and buffer_size to mapnik.VectorTile constructor.

3.4.17

• Binaries updated to use v3.0.10 and mapnik-packaging@d6ae1fb
• Upgraded to protozero v1.3.0
• Fixed invalid usage of mapbox::variant that was causing windows compiler crash

Notable Changes in Mapnik v3.0.10 include:

• A shapefile index now is skipped instead of causing an error to be throw. The shapefile plugin will then proceed by reading without using an index. It is advisable to regenerate the indexes to maintain top performance.

Notable changes in the Mapnik SDK include:

• sqlite 3100000->3110000
• libpng 1.6.20->1.6.21
• postgres 9.4.5->9.5.1
• sparsehash 2.0.2->2.0.3

3.4.16

• Fixed image.resize behavior when scaling images with alpha (https://github.com/mapnik/node-mapnik/issues/585)
• Binaries updated to use v3.0.9-125-g5e30aee and mapnik-packaging@db696ed

Notable Changes in Mapnik v3.0.9-125-g5e30aee include:

• Compare: https://github.com/mapnik/mapnik/compare/v3.0.9-48-gbb8cd10...v3.0.9-125-g5e30aee
• Support for rendering dash-array in SVGs
• SVG parser is now stricter (fails is all input is not parsable)
• SVG parser now correctly handles optional separator (,) between multiple command parts
• Optimized parsing of png format string
• The memory_datasource now dynamically reports correct datasource type (vector or raster)
• Upgraded mapbox::variant@272f91c

Notable changes in the Mapnik SDK include:

• none

3.4.15

• vtile.query now returns WGS84 x_hit and y_hit values of the nearest point/vertex
• Upgraded to nan@2.2.0
• Upgraded to mapnik-vector-tile@0.14.4

3.4.14

• Binaries updated to use Mapnik v3.0.9-57-g9494bc1 and mapnik-packaging@039aa0d

Notable Changes in Mapnik v3.0.9-57-g9494bc1 include:

• Fixed parsing of SVG PathElement (https://github.com/mapnik/mapnik/issues/3225)

3.4.13

• BREAKING: shapefile index files must be regenerated if using the node-mapnik binaries which now default to Mapnik v3.0.9-48-gbb8cd10 (see Notable Changes in Mapnik below for details).
• Upgraded to node-pre-gyp@0.6.19
• Upgraded to mapnik-vector-tile@0.14.2
  • Fixed premultiplication bug in raster encoding (#170)
• Binaries updated to use Mapnik v3.0.9-48-gbb8cd10 and mapnik-packaging@039aa0d

Notable Changes in Mapnik v3.0.9-48-gbb8cd10 include:

• BREAKING: any .index files accompanying a .shp must now be regenerated otherwise an error will be throw like Error: invalid index file. To avoid this error you can either delete the existing .index files, or ideally run shapeindex (or mapnik-shapeindex.js) to recreate the .index. The trigger for this change was an optimization that required a new binary format for the shapefile indexes (https://github.com/mapnik/mapnik/pull/3217). It was a mistake of @springmeyer to bring this into node-mapnik minor release (I'm sorry).
• WARNING: index files generated with this newer Mapnik are invalid for older versions of Mapnik.
• Compare: https://github.com/mapnik/mapnik/compare/v3.0.9...v3.0.9-48-gbb8cd10
• The shapeindex command now has a --index-parts option
• Upgraded mapbox::variant@3ac6e46
• JSON parsing now supports arbitrary (nested) attributes in geometry

Notable changes in the Mapnik SDK include:

• Upgrade libpng 1.6.19 -> 1.6.20
• Upgrade webp 0.4.4 -> 0.5.0
• Upgrade sqlite3 3.9.2 -> 3.10.0
