Rob Wu 1731c0fb42 Add mozPrintCallback shim

This shim does the following:
1. Intercept window.print()
2. For a window.print() call (if allowed, ie. no previous print job):
   1. Dispatch the beforeprint event.
   2. Render a printg progress dialog.
   3. For each canvas, call mozPrintCallback if existent (one at a time, async).
   4. During each mozPrintCallback callback, update the progress dialog.
   5. When all <canvas>es have been rendered, invoke the real window.print().
   6. Dispatch the afterprint event.

The shim is not included in Firefox through the preprocessor.

Keyboard shortcuts (Ctrl/Cmd + P) are intercepted and default behavior
(i.e. printing) is prevented, and the steps for window.print() are run.
window.attachEvent is used, in order to cancel printing in IE10 and
earlier (courtesy of Stack Overflow - http://stackoverflow.com/a/15302847).
Unfortunately, this doesn't work in IE11 - if Ctrl + P is used, the
print dialog will be shown twice: Once because of Ctrl + P, and again
when all pages have finished rendering.

This logic of this polyfill is not specific to PDF.js, so it can also
be used in other projects.

There's one additional modification in PDF.js's viewer.js: The printed
<canvas> element is wrapped in a <div>. This is needed, because Chrome
would otherwise print one canvas on two pages.

PDF.js

PDF.js is 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:

For further questions or guidance feel free to stop by #pdfjs on irc.mozilla.org.

Getting Started

Online demo

http://mozilla.github.io/pdf.js/web/viewer.html

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 to Tools > Extension and load the (unpackaged) extension from the directory build/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

http://localhost:8888/web/viewer.html

You can also view all the test pdf files on the right side serving

http://localhost:8888/test/pdfs/?frame

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.
