Rob Wu fd29bb0c57 Subtract start offset for xrefs in recovery mode

Xref offsets are relative to the start of the PDF data, not to the start
of the PDF file. This is clear if you look at the other code:

- In the XRef's readXRefTable and processXRefTable methods of XRef, the
  offset of a xref entry is set to the bytes as given by a PDF file.
  These values are always relative to the start of the PDF file (%PDF-).

- The XRef's readXRef method adds the start offset of the stream to
  Xref entry's offset: "stream.pos = startXRef + stream.start".
  Clearly, this line assumes that the entry offset excludes the start
  offset.

However, when the PDF is parsed in recovery mode, the xref table is
filled with entries whose offset is relative to the start of the stream
rather than the PDF file. This is incorrect, and the fix is to subtract
the start offset of the stream from the entry's byte offset.

The manually created PDF file serves as a regression test. It is a valid
PDF, except:
- The integer to point to the start of the xref table and the %%EOF
  trailer are missing. This will activate recovery mode in PDF.js
- Some junk was added before the start of the PDF file. This exposes the
  bad offset bug.

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:

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 one extension is still available:

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.

Chrome and Opera

The official extension for Chrome can be installed from the Chrome Web Store. This extension is maintained by @Rob--W.
Opera has also published an extension for their browser at the Opera add-ons catalog.
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.

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
$ cd pdf.js

Next, install Node.js via the official package or via nvm. If everything worked out, run

$ npm install

to install all dependencies for PDF.js.

Finally you need to start a local web server as some browsers do not allow opening PDF files using a file:// URL. Run

$ node make server

and then you can open

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

It is also possible to view all test PDF files on the right side by opening

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.
