This is a tentative patch that adds *very* basic support for non-embedded Wingdings fonts (a Windows version of Dingbats), by falling back to the ZapfDingbats encoding. Obviously this approach will not work perfectly, but in my opinion it seems to work reasonably well in pratice. Instead of this very simple patch, another option would be to try and include more complete glyph data for Wingdings, e.g. a Unicode map and glyph widths, similar to what was done for ZapfDingbats. However there is, in my opinion, one important difference between Wingdings and ZapfDingbats: ZapfDingbats is part of the 14 standard fonts, which in previous versions of the PDF specification was assumed to be available in PDF readers. To improve compatibility with older files, it thus makes sense for us to include data for ZapfDingbats. However Wingdings has never been a standard font in PDF files, hence PDF files using it *should* thus contain all the necessary font data. Given the above, I thus believe that it should be OK to fall back to ZapfDingbats for now. If non-embedded Wingdings fonts turns out to be *a lot* more common, then we can revisit this later. Fixes 4301 completely. Fixes 4837 almost completely. With this patch the bullets are displayed correctly, but the arrows are not of the correct type. Fixes `artofwar.pdf`, pages 14 and 15.
PDF.js
PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.
PDF.js is community-driven and supported by Mozilla Labs. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.
Contributing
PDF.js is an open source project and always looking for more contributors. To get involved checkout:

Getting Started
Online demo
Browser Extensions
Firefox
PDF.js is built into version 19+ of Firefox, however two extensions are still available that are updated at a different rate:
- Development Version - This version is updated every time new code is merged into the PDF.js codebase. This should be quite stable but still might break from time to time.
- Stable Version - After version 24 of Firefox is released we no longer plan to support the stable extension. The stable version will then be considered whatever is built into Firefox.
Chrome and Opera
The Chromium extension is still somewhat experimental but it can be installed two ways:
- Unofficial Version - This extension is maintained by a PDF.js contributor.
- Build Your Own - Get the code as explained below and issue
node make chromium. Then open Chrome, go toTools > Extensionand load the (unpackaged) extension from the directorybuild/chromium.
The version of the extension for the Opera browser can be found at the Opera add-ons catalog.
Getting the Code
To get a local copy of the current code, clone it using git:
$ git clone git://github.com/mozilla/pdf.js.git pdfjs
$ cd pdfjs
Next, you need to start a local web server as some browsers don't allow opening PDF files for a file:// url:
$ node make server
You can install Node via nvm or the official package. If everything worked out, you can now serve
You can also view all the test pdf files on the right side serving
Building PDF.js
In order to bundle all src/ files into two productions scripts and build the generic
viewer, issue:
$ node make generic
This will generate pdf.js and pdf.worker.js in the build/generic/build/ directory.
Both scripts are needed but only pdf.js needs to be included since pdf.worker.js will
be loaded by pdf.js. If you want to support more browsers than Firefox you'll also need
to include compatibility.js from build/generic/web/. The PDF.js files are large and
should be minified for production.
Learning
You can play with the PDF.js API directly from your browser through the live demos below:
The repo contains a hello world example that you can run locally:
