#### JavaScript HTML renderer ####
|
||||
|
||||
The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser. The screenshot is based on the DOM and as such may not be 100% accurate to the real representation as it does not make an actual screenshot, but builds the screenshot based on the information available on the page.
|
||||
|
||||
|
||||
### How does it work? ###
|
||||
The script renders the current page as a canvas image, by reading the DOM and the different styles applied to the elements.
|
||||
|
||||
It does **not require any rendering from the server**, as the whole image is created on the **client's browser**. However, as it is heavily dependent on the browser, this library is *not suitable* to be used in nodejs.
|
||||
It doesn't magically circumvent any browser content policy restrictions either, so rendering cross-origin content will require a [proxy](https://github.com/niklasvh/html2canvas/wiki/Proxies) to get the content to the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy).
|
||||
|
||||
The script is still in a **very experimental state**, so I don't recommend using it in a production environment nor start building applications with it yet, as there will be still major changes made.
|
||||
|
||||
### Browser compatibility ###
|
||||
|
||||
The library should work fine on the following browsers (with `Promise` polyfill):
|
||||
|
||||
* Firefox 3.5+
|
||||
* Google Chrome
|
||||
* Opera 12+
|
||||
* IE9+
|
||||
* Safari 6+
|
||||
|
||||
As each CSS property needs to be manually built to be supported, there are a number of properties that are not yet supported.
|
||||
|
||||
### Usage ###
|
||||
|
||||
The html2canvas library utilizes `Promise`s and expects them to be available in the global context. If you wish to
|
||||
support [older browsers](http://caniuse.com/#search=promise) that do not natively support `Promise`s, please include a polyfill such as
|
||||
[es6-promise](https://github.com/jakearchibald/es6-promise) before including `html2canvas`.
|
||||
|
||||
**Note!** These instructions are for using the current dev version of 0.5, for the latest release version (0.4.1), checkout the [old readme](https://github.com/niklasvh/html2canvas/blob/v0.4/readme.md).
|
||||
|
||||
To render an `element` with html2canvas, simply call:
|
||||
` html2canvas(element[, options]);`
|
||||
|
||||
The function returns a [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) containing the `<canvas>` element. Simply add a promise fullfillment handler to the promise using `then`:
|
||||
|
||||
html2canvas(document.body).then(function(canvas) {
|
||||
document.body.appendChild(canvas);
|
||||
});
|
||||
|
||||
### Building ###
|
||||
|
||||
You can download ready builds [here](https://github.com/niklasvh/html2canvas/releases).
|
||||
|
||||
Clone git repository:
|
||||
|
||||
$ git clone git://github.com/niklasvh/html2canvas.git
|
||||
|
||||
Install dependencies:
|
||||
|
||||
$ npm install
|
||||
|
||||
Build browser bundle
|
||||
|
||||
$ npm run build
|
||||
|
||||
### Running tests ###
|
||||
|
||||
The library has two sets of tests. The first set is a number of qunit tests that check that different values parsed by browsers are correctly converted in html2canvas. To run these tests with grunt you'll need [phantomjs](http://phantomjs.org/).
|
||||
|
||||
The other set of tests run Firefox, Chrome and Internet Explorer with [webdriver](https://github.com/niklasvh/webdriver.js). The selenium standalone server (runs on Java) is required for these tests and can be downloaded from [here](http://code.google.com/p/selenium/downloads/list). They capture an actual screenshot from the test pages and compare the image to the screenshot created by html2canvas and calculate the percentage differences. These tests generally aren't expected to provide 100% matches, but while committing changes, these should generally not go decrease from the baseline values.
|
||||
|
||||
Start by downloading the dependencies:
|
||||
|
||||
$ npm install
|
||||
|
||||
Run tests:
|
||||
|
||||
$ npm test
|
||||
|
||||
### Examples ###
|
||||
|
||||
For more information and examples, please visit the [homepage](https://html2canvas.hertzen.com) or try the [test console](http://html2canvas.hertzen.com/screenshots.html).
|
||||
|
||||
### Contributing ###
|
||||
|
||||
If you wish to contribute to the project, please send the pull requests to the develop branch. Before submitting any changes, try and test that the changes work with all the support browsers. If some CSS property isn't supported or is incomplete, please create appropriate tests for it as well before submitting any code changes.

This is a nonsensical document, but syntactically valid HTML 4.0. All 100% conformant CSS1 agents should be able to render the document elements above this paragraph <b>indistinguishably</b> (to the pixel) from this reference rendering, (except font rasterization and form widgets). All discrepancies should be traceable to CSS1 implementation shortcomings. Once you have finished evaluating this test, you can return to the <A HREF="sec5526c.htm" style="text-decoration:none">parent page</A>.

|
||||
|
||||
Before you get started with the script, there are a few things that are good to know regarding the
|
||||
script and some of its limitations.
|
||||
|
||||
## Introduction
|
||||
The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser.
|
||||
The screenshot is based on the DOM and as such may not be 100% accurate to the real representation
|
||||
as it does not make an actual screenshot, but builds the screenshot based on the information
|
||||
available on the page.
|
||||
|
||||
## How it works
|
||||
The script traverses through the DOM of the page it is loaded on. It gathers information on all the elements
|
||||
there, which it then uses to build a representation of the page. In other words, it does not actually take a
|
||||
screenshot of the page, but builds a representation of it based on the properties it reads from the DOM.
|
||||
|
||||
|
||||
As a result, it is only able to render correctly properties that it understands, meaning there are many
|
||||
CSS properties which do not work. For a full list of supported CSS properties, check out the
|
||||
[supported features](/features/) page.
|
||||
|
||||
## Limitations
|
||||
All the images that the script uses need to reside under the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy)
|
||||
for it to be able to read them without the assistance of a [proxy](/proxy/). Similarly, if you have other `canvas`
|
||||
elements on the page, which have been tainted with cross-origin content, they will become dirty and no longer readable by html2canvas.
|
||||
|
||||
The script doesn't render plugin content such as Flash or Java applets.
|
||||
|
||||
## Browser compatibility
|
||||
|
||||
The library should work fine on the following browsers (with `Promise` polyfill):
|
||||
- Firefox 3.5+
|
||||
- Google Chrome
|
||||
- Opera 12+
|
||||
- IE9+
|
||||
- Edge
|
||||
- Safari 6+

title: "FAQ"
|
||||
description: "Explore Frequently Asked Questions regarding html2canvas"
|
||||
---
|
||||
|
||||
## Why aren't my images rendered?
|
||||
html2canvas does not get around content policy restrictions set by your browser. Drawing images that reside outside of
|
||||
the [origin](https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy) of the current page [taint the
|
||||
canvas](https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image#What_is_a_tainted_canvas) that they are drawn upon. If the canvas gets tainted, it cannot be read anymore. As such, html2canvas implements
|
||||
methods to check whether an image would taint the canvas before applying it. If you have set the `allowTaint`
|
||||
[option](/configuration) to `false`, it will not draw the image.
|
||||
|
||||
If you wish to load images that reside outside of your pages origin, you can use a [proxy](/proxy) to load the images.
|
||||
|
||||
## Why is the produced canvas empty or cuts off half way through?
|
||||
Make sure that `canvas` element doesn't hit [browser limitations](https://stackoverflow.com/questions/6081483/maximum-size-of-a-canvas-element) for the `canvas` size.
|
||||
The limitations vary by browser, operating system and system hardware.
|
||||
|
||||
### Chrome
|
||||
> Maximum height/width: 32,767 pixels
|
||||
> Maximum area: 268,435,456 pixels (e.g., 16,384 x 16,384)
|
||||
|
||||
### Firefox
|
||||
> Maximum height/width: 32,767 pixels
|
||||
> Maximum area: 472,907,776 pixels (e.g., 22,528 x 20,992)
|
||||
|
||||
### Internet Explorer
|
||||
> Maximum height/width: 8,192 pixels
|
||||
> Maximum area: N/A
|
||||
|
||||
### iOS
|
||||
> The maximum size for a canvas element is 3 megapixels for devices with less than 256 MB RAM and 5 megapixels for devices with greater or equal than 256 MB RAM
|
||||
|
||||
## Why doesn't CSS property X render correctly or only partially?
|
||||
As each CSS property needs to be manually coded to render correctly, html2canvas will *never* have full CSS support.
|
||||
The library tries to support the most [commonly used CSS properties](/features) to the extent that it can. If some CSS property
|
||||
is missing or incomplete and you feel that it should be part of the library, create test cases for it and a new issue for it.
|
||||
|
||||
## How do I get html2canvas to work in a browser extension?
|
||||
You shouldn't use html2canvas in a browser extension. Most browsers have native support for capturing screenshots from
|
||||
tabs within extensions. Relevant information for [Chrome](https://developer.chrome.com/extensions/tabs#method-captureVisibleTab) and
|
||||
[Firefox](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D#drawWindow()).

## Installing
|
||||
|
||||
You can install `html2canvas` through npm or [download a built release](https://github.com/niklasvh/html2canvas/releases).
|
||||
|
||||
### npm
|
||||
|
||||
npm install html2canvas

|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
To render an `element` with html2canvas with some (optional) [options](/configuration/), simply call `html2canvas(element, options);`
|
||||
|
||||
```javascript
|
||||
html2canvas(document.body).then(function(canvas) {
|
||||
document.body.appendChild(canvas);
|
||||
});
|
||||
```

html2canvas does not get around content policy restrictions set by your browser. Drawing images that reside outside of

the origin of the current page taint the canvas that they are drawn upon. If the canvas gets tainted,

it cannot be read anymore. If you wish to load images that reside outside of your pages origin, you can use a proxy to load the images.

This is a nonsensical document, but syntactically valid HTML 4.0. All 100% conformant CSS1 agents should be able to render the document elements above this paragraph <b>indistinguishably</b> (to the pixel) from this reference rendering, (except font rasterization and form widgets). All discrepancies should be traceable to CSS1 implementation shortcomings. Once you have finished evaluating this test, you can return to the <A HREF="sec5526c.htm" style="text-decoration:none">parent page</A>.

html2canvas
|
||||
===========
|
||||
|
||||
#### JavaScript HTML renderer ####
|
||||
|
||||
This script allows you to take "screenshots" of webpages or parts of it, directly on the users browser. The screenshot is based on the DOM and as such may not be 100% accurate to the real representation as it does not make an actual screenshot, but builds the screenshot based on the information available on the page.
|
||||
|
||||
|
||||
###How does it work?###
|
||||
The script renders the current page as a canvas image, by reading the DOM and the different styles applied to the elements. However, as many elements are displayed differently on different browsers and operating systems (such as form elements such as radio buttons or checkboxes) as well as
|
||||
|
||||
It does <b>not require any rendering from the server</b>, as the whole image is created on the <b>clients browser</b>. However, for browsers without <code>canvas</code> support alternatives such as <a href="http://flashcanvas.net/">flashcanvas</a> or <a href="http://excanvas.sourceforge.net/">ExplorerCanvas</a> are necessary to create the image.
|
||||
|
||||
Additionally, to render <code>iframe</code> content or images situated outside of the <a href="http://en.wikipedia.org/wiki/Same_origin_policy">same origin policy</a> a proxy will be necessary to load the content to the users browser.
|
||||
|
||||
The script is still in a very experimental state, so I don't recommend using it in a production environment nor start building applications with it yet, as there will be still major changes made. However, please do test it out and report your findings, especially if something should be working, but is displaying it incorrectly.
|
||||
|
||||
###Browser compatibility###
|
||||
|
||||
The script should work fine on the following browsers:
|
||||
|
||||
* Firefox 3.5+
|
||||
* Google Chrome
|
||||
* Newer versions of Opera (exactly how new is yet to be determined)
|
||||
* >=IE9 (Older versions compatible with the use of flashcanvas)
|
||||
|
||||
Note that the compatibility will most likely be increased in future builds, as many of the current restrictions have at least partial work arounds, which can be used with older browser versions.
|
||||
|
||||
###So what isn't included yet?###
|
||||
|
||||
There are still a lot of CSS properties missing, including most CSS3 properties such as <code>text-shadow</code>, <code>box-radius</code> etc. as well as all elements created by the browser, such as radio and checkbox buttons and list icons. I will compile a full list of supported elements and CSS properties soon.
|
||||
There is no support for <code>frame</code> and <code>object</code> content such as Flash.
|
||||
|
||||
### Examples ###

The whole screenshot is created with JavaScript. The only server interaction that is happening on this page is the proxy for loading the external pages/images into JSONP/CORS enabled page and onwards onto the JavaScript renderer script.
|
||||
There are a lot of problems of loading external pages, even with a proxy, and as such many pages will not render at all. If you wish to try the script properly, I recommend you get a copy of the source from <a href="https://github.com/niklasvh/html2canvas">here</a> instead.
