Jonas Jenwald 7f21e38787 Error, rather than warn, once a number of invalid path operators are encountered in EvaluatorPreprocessor.read (bug 1443140) 
Incomplete path operators, in particular, can result in fairly chaotic rendering artifacts, as can be observed on page four of the referenced PDF file.

The initial (naive) solution that was attempted, was to simply throw a `FormatError` as soon as any invalid (i.e. too short) operator was found and rely on the existing `ignoreErrors` code-paths. However, doing so would have caused regressions in some files; see the existing `issue2391-1` test-case, which was promoted to an `eq` test to help prevent future bugs.
Hence this patch, which adds special handling for invalid path operators since those may cause quite bad rendering artifacts.

You could, in all fairness, argue that the patch is a handwavy solution and I wouldn't object. However, given that this only concerns *corrupt* PDF files, the way that PDF viewers (PDF.js included) try to gracefully deal with those could probably be described as a best-effort solution anyway.

This patch also adjusts the existing `warn`/`info` messages to print the command name according to the PDF specification, rather than an internal PDF.js enumeration value. The former should be much more useful for debugging purposes.

README.md

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, visit:

Feel free to stop by #pdfjs on irc.mozilla.org for questions or guidance.

Getting Started

Online demo

Browser Extensions

Firefox

PDF.js is built into version 19+ of Firefox.

Chrome

  • The official extension for Chrome can be installed from the Chrome Web Store. This extension is maintained by @Rob--W.
  • Build Your Own - Get the code as explained below and issue gulp 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. You need to install the gulp package globally (see also gulp's getting started):

$ npm install -g gulp-cli

If everything worked out, install all dependencies for PDF.js:

$ npm install

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

$ gulp server

and then you can open:

Please keep in mind that this requires an ES6 compatible browser; refer to Building PDF.js for usage with older browsers.

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

Building PDF.js

In order to bundle all src/ files into two production scripts and build the generic viewer, run:

$ gulp 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. The PDF.js files are large and should be minified for production.

Using PDF.js in a web application

To use PDF.js in a web application you can choose to use a pre-built version of the library or to build it from source. We supply pre-built versions for usage with NPM and Bower under the pdfjs-dist name. For more information and examples please refer to the wiki page on this subject.

Including via a CDN

PDF.js is hosted on several free CDNs:

Learning

You can play with the PDF.js API directly from your browser using the live demos below:

The repository contains a hello world example that you can run locally:

More examples can be found in the examples folder. Some of them are using the pdfjs-dist package, which can be built and installed in this repo directory via gulp dist-install command.

For an introduction to the PDF.js code, check out the presentation by our contributor Julian Viereck:
