Creating your first document

The easiest way to get started is to drop the CDN hosted library into your page:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.debug.js" integrity="sha384-NaWTHo/8YCBYJ59830LTz/P4aQZK1sS0SneOgAvhsIl3zBu8r9RevNg5lHCHAuQ/" crossorigin="anonymous"></script>

Integrity-hash generated by https://www.srihash.org/

or can always get latest version via unpkg

<script src="https://unpkg.com/[email protected]/dist/jspdf.min.js"></script>

Using yarn:

yarn add jspdf

Using npm:

npm install jspdf --save

Then you're ready to start making your document:

// Default export is a4 paper, portrait, using millimeters for units var doc = new jsPDF() doc.text('Hello world!', 10, 10) doc.save('a4.pdf')

If you want to change the paper size, orientation, or units, you can do:

// Landscape export, 2×4 inches var doc = new jsPDF({ orientation: 'landscape', unit: 'in', format: [4, 2] }) doc.text('Hello world!', 1, 1) doc.save('two-by-four.pdf')

Use of UTF-8 / TTF:

The 14 standard fonts in PDF are limited to the ASCII-codepage. If you want to use UTF-8 you have to to integrate a custom font, which provides the needed glyphs. jsPDF supports .ttf-files. So if you want to have for example chinese text in your pdf, your font has to have the necessary chinese glyphs. So check if your font supports the wanted glyphs or else it will show a blank space instead of the text.

To add the font to jsPDF use our fontconverter in /fontconverter/fontconverter.html . The fontconverter will create a js-file with the content of the provided ttf-file as base64 encoded string and additional code for jsPDF. You just have to add this generated js-File to your project. You are then ready to go to use setFont-method in your code and write your UTF-8 encoded text.

Angular/Webpack/React/etc. Configuration:

If you are using Webpack (including managed cli tools like angular-cli or create-react-app) you can import like this:

import \* as jsPDF from 'jspdf'

In some frameworks you have to import jsPDF like this:

import jsPDF from 'jspdf';

You can add jsPDF to your meteor-project as follows:

meteor add jspdf:core

Advanced Functionality

Since the merge with the yWorks fork there are a lot of new features. However, some of them are API breaking, which is why there is an API-switch between two API modes:

  • In "compat" API mode, jsPDF has the same API as MrRio's original version, which means full compatibility with plugins. However, some advanced features like transformation matrices and patterns won't work. This is the default mode.
  • In "advanced" API mode, jsPDF has the API you're used from the yWorks-fork version. This means the availability of all advanced features like patterns, FormObjects and transformation matrices.

You can switch between the two modes by calling

javascript doc.advancedAPI(doc =\> { // your code }) // or doc.compatAPI(doc =\> { // your code })

JsPDF will automatically switch back to the original API mode after the callback has run.
