+# PDF.js issue reporting
+
+The issues are used to track both bugs filed by users and specific work items for developers. Try to file one issue per problem observed. Please specify a valid title (e.g. "Glyph spacing is incorrect" instead of "PDF.js does not work") and provide more details about the issue: link to the PDF, location in the PDF, screenshot, browser version, operating system, PDF.js version and JavaScript console warning/error messages. Issues that do not have enough details provided will be closed as invalid/incomplete.
+
+If the issue is related to errors produced by a specific PDF, please always include the PDF by providing a URL where contributors can download it. Without a PDF for reproduction, such issues will be closed. We understand that many PDFs contain sensitive information, however having a PDF is essential to resolving the issue and building our regression testing suite. If possible, try creating a reduced example exhibiting the problem but not containing sensitive data. Also small PDFs are best suited for our regression testing. If an important issue only shows on sensitive PDFs, contributors might be willing to accept these PDFs via a secure exchange.
+
+The issue tracking system is designed to record a single technical problem. A bug report is something where a developer/contributor can work on. The GitHub issue tracker is not a good place for general, not well thought out or unworkable ideas. Most likely a discussion-type issue will not be addressed for a long time or closed as invalid. The best place for general discussions is our Matrix room at https://chat.mozilla.org/#/room/#pdfjs:mozilla.org.
+
+If you are developing a custom solution, first check the examples at https://github.com/mozilla/pdf.js#learning and search existing issues. If this does not help, please prepare a short well-documented example that demonstrates the problem and make it accessible online on your website, JS Bin, GitHub, etc. before opening a new issue or contacting us in the Matrix room -- keep in mind that just code snippets won't help us troubleshoot the problem.
+
+Note that the translations for PDF.js in the `l10n` folder are imported from the Nightly channel of Mozilla Firefox, such that we don't have to maintain them ourselves. This means that we will not accept pull requests that add new languages and/or modify existing translations, unless the corresponding changes have been made in Mozilla Firefox first.

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# PDF.js [![Build Status](https://github.com/mozilla/pdf.js/workflows/CI/badge.svg?branch=master)](https://github.com/mozilla/pdf.js/actions?query=workflow%3ACI+branch%3Amaster)
+
+[PDF.js](https://mozilla.github.io/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:
+
++ [Issue Reporting Guide](https://github.com/mozilla/pdf.js/blob/master/.github/CONTRIBUTING.md)
++ [Code Contribution Guide](https://github.com/mozilla/pdf.js/wiki/Contributing)
++ [Frequently Asked Questions](https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions)
++ [Good Beginner Bugs](https://github.com/mozilla/pdf.js/issues?direction=desc&labels=good-beginner-bug&page=1&sort=created&state=open)
++ [Projects](https://github.com/mozilla/pdf.js/projects)
+
+Feel free to stop by our [Matrix room](https://chat.mozilla.org/#/room/#pdfjs:mozilla.org) for questions or guidance.
+
+## Getting Started
+
+### Online demo
+
+Please note that the "Modern browsers" version assumes native support for
+features such as optional chaining, nullish coalescing,
+and private `class` fields/methods; please also see [this wiki page](https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#faq-support).
+
++ Modern browsers: https://mozilla.github.io/pdf.js/web/viewer.html
+
++ Older browsers: https://mozilla.github.io/pdf.js/legacy/web/viewer.html
+
+### Browser Extensions
+
+#### Firefox
+
+PDF.js is built into version 19+ of Firefox.
+
+#### Chrome
+
++ 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](https://nodejs.org) or via
+[nvm](https://github.com/creationix/nvm). You need to install the gulp package
+globally (see also [gulp's getting started](https://github.com/gulpjs/gulp/tree/master/docs/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:
+
++ http://localhost:8888/web/viewer.html
+
+Please keep in mind that this requires a modern and fully up-to-date browser; refer to [Building PDF.js](https://github.com/mozilla/pdf.js/blob/master/README.md#building-pdfjs) for non-development usage of the PDF.js library.
+
+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 production scripts and build the generic
+viewer, run:
+
+    $ gulp generic
+
+If you need to support older browsers, run:
+
+    $ gulp generic-legacy
+
+This will generate `pdf.js` and `pdf.worker.js` in the `build/generic/build/` directory (respectively `build/generic-legacy/build/`).
+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](https://github.com/mozilla/pdf.js/wiki/Setup-pdf.js-in-a-website) on this subject.
+
+## Including via a CDN
+
+PDF.js is hosted on several free CDNs:
+ - https://www.jsdelivr.com/package/npm/pdfjs-dist
+ - https://cdnjs.com/libraries/pdf.js
+ - https://unpkg.com/pdfjs-dist/
+
+## Learning
+
+You can play with the PDF.js API directly from your browser using the live demos below:
+
++ [Interactive examples](https://mozilla.github.io/pdf.js/examples/index.html#interactive-examples)
+
+More examples can be found in the [examples folder](https://github.com/mozilla/pdf.js/tree/master/examples/). Some of them are using the pdfjs-dist package, which can be built and installed in this repo directory via `gulp dist-install` command.

+## Hello World Walkthrough
+
+[Full source](https://github.com/mozilla/pdf.js/blob/master/examples/learning/helloworld.html)
+
+PDF.js heavily relies on the use of [Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise). If promises are new to you, it's recommended you become familiar with them before continuing on.
+
+This tutorial shows how PDF.js can be used as a library in a web browser.
+[examples/](https://github.com/mozilla/pdf.js/tree/master/examples) provides more examples, including usage in Node.js (at [examples/node/](https://github.com/mozilla/pdf.js/tree/master/examples/node)).
+
+### Document
+
+The object structure of PDF.js loosely follows the structure of an actual PDF. At the top level there is a document object. From the document, more information and individual pages can be fetched. To get the document:
+
+```js
+pdfjsLib.getDocument('helloworld.pdf')
+```
+
+Remember though that PDF.js uses promises, and the above will return a `PDFDocumentLoadingTask` instance that has a `promise` property which is resolved with the document object.
+
+```js
+var loadingTask = pdfjsLib.getDocument('helloworld.pdf');
+loadingTask.promise.then(function(pdf) {
+  // you can now use *pdf* here
+});
+```
+
+### Page
+Now that we have the document, we can get a page. Again, this uses promises.
+
+```js
+pdf.getPage(1).then(function(page) {
+  // you can now use *page* here
+});
+```
+
+### Rendering the Page
+Each PDF page has its own viewport which defines the size in pixels(72DPI) and initial rotation. By default the viewport is scaled to the original size of the PDF, but this can be changed by modifying the viewport. When the viewport is created, an initial transformation matrix will also be created that takes into account the desired scale, rotation, and it transforms the coordinate system (the 0,0 point in PDF documents the bottom-left whereas canvas 0,0 is top-left).
+
+```js
+var scale = 1.5;
+var viewport = page.getViewport({ scale: scale, });
+// Support HiDPI-screens.
+var outputScale = window.devicePixelRatio || 1;
+
+var canvas = document.getElementById('the-canvas');
+var context = canvas.getContext('2d');
+
+canvas.width = Math.floor(viewport.width * outputScale);
+canvas.height = Math.floor(viewport.height * outputScale);
+canvas.style.width = Math.floor(viewport.width) + "px";
+canvas.style.height =  Math.floor(viewport.height) + "px";
+
+var transform = outputScale !== 1
+  ? [outputScale, 0, 0, outputScale, 0, 0]
+  : null;
+
+var renderContext = {
+  canvasContext: context,
+  transform: transform,
+  viewport: viewport
+};
+page.render(renderContext);
+```
+
+Alternatively, if you want the canvas to render to a certain pixel size you could do the following:
+
+```js
+var desiredWidth = 100;
+var viewport = page.getViewport({ scale: 1, });
+var scale = desiredWidth / viewport.width;
+var scaledViewport = page.getViewport({ scale: scale, });
+```
+
+## Interactive examples
+
+### Hello World with document load error handling
+
+The example demonstrates how promises can be used to handle errors during loading.
+It also demonstrates how to wait until a page is loaded and rendered.
+
+<script async src="//jsfiddle.net/pdfjs/9engc9mw/embed/js,html,css,result/"></script>
+
+### Hello World using base64 encoded PDF
+
+The PDF.js can accept any decoded base64 data as an array.
+
+<script async src="//jsfiddle.net/pdfjs/cq0asLqz/embed/js,html,css,result/"></script>
+
+### Previous/Next example
+
+The same canvas cannot be used to perform to draw two pages at the same time --
+the example demonstrates how to wait on previous operation to be complete.
+
+<script async src="//jsfiddle.net/pdfjs/wagvs9Lf/embed/js,html,css,result/"></script>

+
+Before downloading PDF.js please take a moment to understand the different layers of the PDF.js project.
+
+<table class="table">
+  <thead>
+    <tr>
+      <th>Layer</th>
+      <th>About</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>Core</td>
+      <td>The core layer is where a binary PDF is parsed and interpreted. This layer is the foundation for all subsequent layers. It is not documented here because using it directly is considered an advanced usage and the API is likely to change. For an example of using the core layer see the <a href="https://github.com/brendandahl/pdf.js.utils/tree/master/browser">PDF Object Browser</a>.
+      </td>
+    </tr>
+    <tr>
+      <td>Display</td>
+      <td>The display layer takes the core layer and exposes an easier to use API to render PDFs and get other information out of a document. This API is what the version number is based on.</td>
+    </tr>
+    <tr>
+      <td>Viewer</td>
+      <td>The viewer is built on the display layer and is the UI for PDF viewer in Firefox and the other browser extensions within the project. It can be a good starting point for building your own viewer. <em>However, we do ask if you plan to embed the viewer in your own site, that it not just be an unmodified version. Please re-skin it or build upon it.</em></td>

+
+## Trying the Viewer
+
+With the prebuilt or source version, open `web/viewer.html` in a browser and the test pdf should load. Note: the worker is not enabled for file:// urls, so use a server. If you're using the source build and have node, you can run `gulp server`.
+
+## More Information
+
+For a further walkthrough of a minimal viewer, see the hello world example. More documentation can be found in our [wiki](https://github.com/mozilla/pdf.js/wiki) too.

+## Overview
+
+Example to demonstrate PDF.js library usage with a viewer optimized for mobile usage.
+
+## Getting started
+
+Build PDF.js using `gulp dist-install` and run `gulp server` to start a web server.
+You can then work with the mobile viewer at
+http://localhost:8888/examples/mobile-viewer/viewer.html.
+
+Refer to `viewer.js` for the source code of the mobile viewer.

+## Overview
+
+Example to demonstrate PDF.js library usage with Webpack.
+
+## Getting started
+
+Install the example dependencies and build the project:
+
+    $ gulp dist-install
+    $ cd examples/webpack
+    $ npm install
+    $ ./node_modules/webpack/bin/webpack.js
+
+You can observe the build results by running `gulp server` and navigating to
+http://localhost:8888/examples/webpack/index.html.
+
+Refer to the `main.js` and `webpack.config.js` files for the source code.
+Note that PDF.js packaging requires packaging of the main application and
+the worker code, and the `workerSrc` path shall be set to the latter file.
+
+### Minification
+
+If you are configuring Webpack to output a minified build, please note that you
+*must* configure the minifier to keep original class/function names intact;
+otherwise the build is not guaranteed to work correctly.
+
+## Worker loading
+
+If you are getting the `Setting up fake worker` warning, make sure you are
+importing `pdfjs-dist/webpack` which is the zero-configuration method for
+Webpack users. Installing `worker-loader` is no longer necessary.
+
+    import * as pdfjsLib from 'pdfjs-dist/webpack';
+
+For a full working example refer to [this repository](https://github.com/yurydelendik/pdfjs-react).
