Node-Podofo

Node-podofo in a Node addons written in C++ to manipulate & read PDF files (create pdf, get metadata, information, author, get text from pdf ...).

This is an updated fork of podofo

Why this fork ?

This fork compile 3 years of podofo dev (from 0.9.3 to 0.9.5) And it add the possibility to DISABLE DEBUG & LOG by default which was really terrible when using with Node.js

Why Node-podofo

Of course you can use pdfjs in full js, but if speed & error catcher are important for you node-podofo is here.

Because it's a native addons written in C++, it is very speed & you can use the function directly in your project just like all npm module.

It's not just a spawn of a command so error, returned value .. can be managed in Javascript as easy as pie.

It fully intregates all require Libraries, nothing to install more.

Bindings for the PoDoFo PDF Library

This project provides Node.js bindings for the PoDoFo PDF library.

Basic functionality has been implemented, but this is generally a work in progress. Pull requests are welcome.

Installing

This requires libpodofo to be installed. If you are using Ubuntu, the following command should suffice:

sudo apt-get install libpodofo-dev

Then, installing this library is as simple as:

npm install podofo

Using with node

const podofo = require('podofo');

let pdf = new podofo.PdfMemDocument(false);
pdf.Load('/path/to/a/file.pdf');

console.log(pdf.GetInfo().GetAuthor());
// Will return software author

Building on Windows

PoDoFo (minimally) depends on zlib and freetype. You will also need the source for PoDoFo itself. You can download these packages and extract them into deps/.

After extraction, the directory tree should look like this:

• deps/
  • freetype/
  • podofo/
  • zlib/

The following versions have been tested:

• freetype: 2.8
• podofo: 0.9.5
• zlib: 1.2.11

Then you just need to run node-pre-gyp configure build to obtain a binary.

Of course, you will also need to have a toolchain installed. This has been tested with Visual Studio 2015. The Community edition is available from Microsoft for free.

Examples

You can exec a simple GetAuthor() & text-extractor:

From your main module(main-module/node_modules/node-podofo) just launch:

node node_modules/node-podofo/index.js

Dev

To complie from source node-podofo just :

git submodule init
git submodule update
npm install --build-from-source

This will recreate the bin in ./lib

Debug & Logs

By default log & debug are disable, to enable them when you can just pass true option to PdfMemDocument as:

var pdf = new podofo.PdfMemDocument(true);

Notice

All Podofo Classes cannot be used directly, for example, PdfError could be called only via c++, not javascript binding. If you want to update this fork, you must know about c++/Node.js, podofo, node-addons, Nan V8, node-pre-gyp, node-pre-gyp-github & use travis for build for OSX+Linux and Appveyor to build for Windows.
