Jonas Jenwald b478d3e7b9 Improve argument/name handling when parsing TilingPatterns (PR 12458 follow-up) 
- Handle the arguments correctly in `PartialEvaluator.handleColorN`.
   For TilingPatterns with a base-ColorSpace, we're currently using the `args` when computing the color. However, as can be seen we're passing the Array as-is to the `ColorSpace.getRgb` method, which means that the `Name` is included as well.[1]
   Thankfully this hasn't, as far as I know, caused any actual bugs, but that may be more luck than anything else given how the `ColorSpace` code is implemented. This can be easily fixed though, simply by popping the `Name`-object off of the `args` Array.

 - Cache TilingPatterns using the `Name`-string, rather than the object directly.
   This is not only consistent with other caches in `PartialEvaluator`, but importantly it also ensures that the cache lookup always works correctly. Note that since `Name`-objects, similar to other primitives, uses a cache themselves a *manually* triggered `cleanup`-call could thus (theoretically) cause the `LocalTilingPatternCache` to not find an existing entry. While the likelihood of this happening is *extremely* small, it's still something that we should fix.

---
[1] The `args` Array can e.g. look like this: `[0.043, 0.09, 0.188, 0.004, /P1]`, which means that we're passing in the `Name`-object to the `ColorSpace` method.

PDF.js Build Status

PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.

PDF.js is community-driven and supported by Mozilla. 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 our Matrix room for questions or guidance.

Getting Started

Online demo

Please note that the "Modern browsers" version assumes native support for features such as e.g. async/await, and ReadableStream.

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 https://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:

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.
