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.

Examples +layout: layout.njk +slug: examples +--- + +## 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. + + + +### Hello World using base64 encoded PDF + +The PDF.js can accept any decoded base64 data as an array. + + + +### 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. + + diff --git a/docs/contents/getting_started/index.md b/docs/contents/getting_started/index.md new file mode 100644 index 0000000..438702b --- /dev/null +++ b/docs/contents/getting_started/index.md @@ -0,0 +1,127 @@ +--- +title: Getting Started +layout: layout.njk +slug: getting_started +--- + +# Getting Started + +An introduction to PDF.js with examples. + +## Introduction + +Before downloading PDF.js please take a moment to understand the different layers of the PDF.js project. + + + + + + + + + + + + + + + + + + + + + + +
LayerAbout
CoreThe 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 PDF Object Browser. +
DisplayThe 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.
ViewerThe 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. 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.

+## 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.mjs` which is the zero-configuration method for
+Webpack users. Installing `worker-loader` is no longer necessary.
+
+    import * as pdfjsLib from 'pdfjs-dist/webpack.mjs';
