 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.

-## Overview
-
-PDF.js is a Portable Document Format (PDF) viewer built with JavaScript, HTML5 Canvas, and CSS. It's a Mozilla project that provides a general-purpose, web standards-based platform for parsing and rendering PDFs without requiring native code or plugins.
-
-## Common Commands
-
-### Development Server
-```bash
-npx gulp server
-```
-Then open http://localhost:8888/web/viewer.html to view the PDF viewer. Test PDFs are available at http://localhost:8888/test/pdfs/?frame
-
-### Building
-
-Build for modern browsers:
-```bash
-npx gulp generic
-```
-
-This generates `pdf.js` and `pdf.worker.js` in `build/generic/build/`.
-
-Build for distribution (creates pdfjs-dist package):
-```bash
-npx gulp dist
-npx gulp dist-install    # Build and install locally
-```
-
-### Testing
-
-Run all tests:
-```bash
-npx gulp test
-```
-
-Run unit tests only:
-```bash
-npx gulp unittest
-```
-
-Run integration tests (browser-based tests using Puppeteer):
-```bash
-npx gulp integrationtest
-```
-
-Run font tests:
-```bash
-npx gulp fonttest
-```
-
-Run a single test file by modifying test/test_manifest.json or using test runner options.
-
-### Linting and Formatting
-
-Lint JavaScript:
-```bash
-npx gulp lint
-```
-
-Format code (uses Prettier and ESLint):
-```bash
-npx eslint --fix <file>
-```
-
-### Type Checking
-
-Run TypeScript type checking:
-```bash
-npx gulp typestest
-```
-
-## Architecture
-
-### High-Level Structure
-
-PDF.js has a multi-layer architecture that separates concerns between PDF parsing, rendering, and UI:
-
-#### 1. Core Layer (`src/core/`)
-The core layer handles PDF parsing and interpretation. Key responsibilities:
-- **PDF parsing**: Parsing PDF structure, cross-reference tables, streams
-- **Font handling**: CFF, TrueType, Type1 font parsing and conversion (`font.js`, `fonts.js`, `cff_*.js`, `type1_*.js`)
-- **Image decoding**: JPEG, JBIG2, JPX/JPEG2000 decoders
-- **Operators**: Processing PDF drawing operators (`operator_list.js`, `evaluator.js`)
-- **XFA Forms**: XML Forms Architecture support (`src/core/xfa/`)
-- **Color spaces**: ICC profiles, device color spaces (`colorspace.js`, `icc_colorspace.js`)
-- Runs in a Web Worker for performance isolation
-
-Entry point: `src/pdf.worker.js`
-
-#### 2. Display Layer (`src/display/`)
-The display layer provides the API for rendering PDFs to canvas and managing documents. Key components:
-- **API**: Main public API (`api.js`) - `PDFDocumentProxy`, `PDFPageProxy`, `getDocument()`
-- **Canvas rendering**: Renders PDF operations to HTML5 canvas (`canvas.js`)
-- **Text layer**: Extracts and positions text for selection/search (`text_layer.js`)
-- **Annotation layer**: Renders and handles PDF annotations (`annotation_layer.js`)
-- **Editor layer**: Supports PDF editing (annotations, highlights, stamps) (`editor/`)
-- **Metadata**: Parses XMP metadata (`metadata.js`)
-- **Streams**: Handles PDF data fetching (fetch, network, node) (`fetch_stream.js`, `network.js`, `node_stream.js`)
-
-Entry point: `src/pdf.js`
-
-#### 3. Scripting Layer (`src/scripting_api/`)
-Implements JavaScript execution for interactive PDFs (form calculations, validations, button actions).
-- Sandboxed execution environment
-- Implements Acrobat JavaScript API objects (App, Doc, Field, etc.)
-
-Entry points: `src/pdf.scripting.js`, `src/pdf.sandbox.js`
-
-#### 4. Web Viewer (`web/`)
-The complete PDF viewer application with UI. Key components:
-- **Main app**: Application orchestration (`app.js`)
-- **Viewer**: Page rendering and layout (`pdf_viewer.js`, `pdf_page_view.js`)
-- **Toolbar**: Zoom, page navigation, print, download controls
-- **Sidebar**: Thumbnails, outlines, attachments (`pdf_sidebar.js`, `pdf_thumbnail_view.js`, `pdf_outline_viewer.js`)
-- **Find controller**: Text search functionality (`pdf_find_controller.js`)
-- **Annotation editors**: UI for creating/editing annotations (`annotation_editor_layer_builder.js`)
-- **Presentation mode**: Full-screen presentation (`pdf_presentation_mode.js`)
-
-Entry point: `web/viewer.html` + `web/viewer.mjs`
-
-#### 5. Shared Utilities (`src/shared/`)
-Common utilities used across layers:
-- **Message handling**: Worker communication (`message_handler.js`)
-- **Utilities**: Common functions and constants (`util.js`)
-- **Image utilities**: Image processing helpers (`image_utils.js`)

-PDF.js uses a Web Worker architecture:
-- Main thread (`display` layer) communicates with worker thread (`core` layer) via `MessageHandler`
-- Keeps PDF parsing off the main thread for better performance
-- Messages include: page rendering requests, text content extraction, metadata queries
-
-### Build System
-
-- Uses **Gulp** for build orchestration (`gulpfile.mjs`)
-- **Webpack** bundles modules into browser-compatible formats
-- **Babel** transpiles for browser compatibility (configurable targets in gulpfile)
-- Preprocessor replaces build-time constants (e.g., `typeof PDFJSDev !== "undefined"` checks)
-- Multiple build targets: generic, components, minified, legacy (older browser support)
-
-### External Dependencies
-
-Located in `external/`:
-- **bcmaps**: Binary CMaps for CJK fonts
-- **standard_fonts**: Core 14 PDF fonts metrics
-- **cmapscompress**: Tools for compressing CMaps
-- **openjpeg**: JPEG2000 decoder (WASM)
-- **quickjs**: JavaScript engine for sandboxed execution
-
-### Translations
-
-Translations in `l10n/` are imported from Mozilla Firefox Nightly. Only the file l10n/en-US/viewer.ftl can be updated.
-
-## Development Notes
-
-### Adding New Features
-
-When adding features that span multiple layers:
-1. Start with the `core` layer if parsing/interpretation changes are needed
-2. Update the `display` layer API if new capabilities need exposure
-3. Modify the `web` viewer if UI changes are required
-4. Ensure worker communication handles new message types
-
-### Preprocessor Directives
-
-Code uses preprocessor checks for build-time conditionals:
-```javascript
-if (typeof PDFJSDev !== "undefined" && PDFJSDev.test("GENERIC")) {
-  // Generic build-specific code
-}
-```
-
-Common flags: `GENERIC`, `MOZCENTRAL`, `CHROME`, `MINIFIED`, `TESTING`, `LIB`, `SKIP_BABEL`, `IMAGE_DECODERS`
-
-### Testing
-
-- Unit tests use Jasmine framework (`test/unit/`)
-- Integration tests use Puppeteer for browser automation (`test/integration/`)
-- Test PDFs downloaded from manifest (`test/test_manifest.json`)
-- Reference images for visual regression testing (`test/ref/`)
-
-### Code Style
-
-- Uses ESLint with custom configuration (`eslint.config.mjs`)
-- Prettier for formatting
-- Stylelint for CSS
-- No semicolons required (ASI enabled)
-- Single quotes for strings
-
-### Pull Request Process
-
-- Keep PRs focused on a single issue
-- Provide a test PDF if the issue is PDF-specific
-- Ensure tests pass (`npx gulp test`)
-- Run linting (`npx gulp lint`)
-- Follow existing code patterns
-- Don't modify translations directly (they come from Firefox)
-
-### Performance Considerations
-
-- Core parsing runs in a Web Worker - keep main thread work minimal
-- Canvas rendering can be expensive - use appropriate scale factors
-- Text layer generation is separate from rendering - can be deferred
-- Annotation layer is optional - only enable when needed

-## Code coverage
-
-We track how much of the code is exercised by the test suite on
-[Codecov](https://codecov.io/gh/mozilla/pdf.js) (see the badge at the top of this
-file).
-
-### How it is collected
-
-When coverage is enabled, the build instruments the bundled code with
-[`babel-plugin-istanbul`](https://github.com/istanbuljs/babel-plugin-istanbul),
-which adds counters that record every line, branch and function that runs:
-
-+ For browser-based tests (unit, integration and reference tests) the
-  instrumented code runs in the browser, fills a global `window.__coverage__`
-  object, and the test runner collects it from each browser session, merges the
-  results, and writes the report.
-+ For the Node-based unit tests (`unittestcli`) the raw data is written to
-  `build/tmp/unittestcli-coverage.json` and turned into a report afterwards.
-
-### Collecting coverage locally
-
-Add the `--coverage` flag to any of the test tasks, for example:
-
-    $ npx gulp unittest --coverage           # browser unit tests
-    $ npx gulp unittestcli --coverage        # Node unit tests
-    $ npx gulp integrationtest --coverage    # Puppeteer integration tests
-    $ npx gulp botbrowsertest --coverage     # reference tests
-
-The following options control the output:
-
-| Option | Description | Default |
-| --- | --- | --- |
-| `--coverage` | Enable coverage collection. | off |
-| `--coverage-output <dir>` | Directory where the report is written. | `build/coverage` |
-| `--coverage-formats <list>` | Comma-separated list of formats: `info`, `html`, `json`, `text`, `cobertura`, `clover`. | `info` |
-| `--coverage-per-test` | Also build a per-test index (see below). | off |
-
-By default the report is written to `build/coverage` in the `info` format, i.e.
-an [LCOV](https://github.com/linux-test-project/lcov) `lcov.info` file (the same
-format that is uploaded to Codecov). Use `--coverage-formats html` to get a
-browsable HTML report instead, or pass several formats at once, e.g.
-`--coverage-formats info,html`.
-
-### Finding which tests cover a given line
-
-Run a browser test task with `--coverage-per-test` to build an index
-(`per-test-index.json`) in the coverage directory, then query it to list the
-tests that exercised a specific source line or function:
-
-    $ npx gulp botbrowsertest --coverage-per-test
-    $ npx gulp coverage_search --code="canvas.js::205"
-    $ npx gulp coverage_search --code="canvas.js::drawImageAtIntegerCoords"
-
-### Continuous integration
-
-On every push and pull request three GitHub Actions workflows collect coverage
-and upload it to Codecov, each tagged with its own Codecov *flag* so the test
-types can be told apart:
-
-| Workflow | Task | Codecov flag |
-| --- | --- | --- |
-| `unit_tests.yml` | `unittest` | `unittest` |
-| `integration_tests.yml` | `integrationtest` | `integrationtest` |
-| `coverage_browser_tests.yml` | `botbrowsertest` | `browsertest` |

 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({ url: "helloworld.pdf" })
+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({ url: "helloworld.pdf" });

-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and

-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          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
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      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
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-   END OF TERMS AND CONDITIONS
-   APPENDIX: How to apply the Apache License to your work.
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
