Temporarily add manual update to es6-promise polyfill
2014-12-29 21:35:22 +02:00
e2713cd6f9 Temporarily add manual update to es6-promise polyfill
This replaces an old and outdated Promise polyfill that was included
with previous versions of html2canvas, and which consistently overwrote
native browser implementations when it shouldn't have. It is essentially
a (slightly modified) paste of the most current minified version of
es6-promise, found here:
https://es6-promises.s3.amazonaws.com/es6-promise-2.0.1.min.js

The plan is to eventually include this polyfill as a submodule
dependency, but the build process for es6-promise is a bit
cumbersome/opaque/painful at the moment, so this manual update was an
easier interim solution.

Please note that I had to manually add the actual call to
`ES6Promise.polyfill()` to load the polyfill--this will become
unnecessarry in future versions of es6-promise. Note also that I had to
manually pass `window` to the polyfill's IIFE, since `this` is an empty
object in the current scope.

Ref niklasvh/html2canvas#494.

f00b23a9ec incorect z-index sorting fixed
If you omit compare function in javascript `sort()` method it will sort  lexicographically (in dictionary order) according to the string conversion of each element. 

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#Parameters

For example 
[0, 9, 8, 10].sort()
will place element with z-index 10 on 2nd position of the array

8bea01b81d Speed & accuracy improvements to pseudo element rendering.
Previously, pseudo elements would be processed as they were found in the DOM tree, which was
an expensive operation as each element's computed :before and :after style was checked for
'content' styles.

This commit traverses the user's stylesheets for :before and :after selectors, gathers the classes
affected, selects all elements that likely have a pseudo element present, then checks computed style.
If there is actually an element present, it is created but *not* appended to the DOM until after
all elements have been processed.

After all elements have been found and created, they are added to the DOM in a single batch, and the original
pseudo elements are hidden in a single batch. This prevents the layout invalidation / relayout loop that was
occuring previously, and in my tests speeds parsing by as much as 50% or more, depending on how many
pseudo elements your page uses.

Additionally, this commit contains a bugfix to the handling of ":before" pseudo elements; the browser effectively
inserts them as the first child of the element, not before the element. This fixes a few rendering inconsistencies
and complicated pages look almost perfect in my tests.
2013-09-18 13:38:21 +08:00
e115180731 Add async parsing option.
In my testing, the major time sink is parsing. This commit adds a setTimeout() around parsing
of each item so control can return to the browser. This increases the total time it takes to finish
a screenshot but will not freeze the browser when it does. This is a good option when e.g. doing
error reporting, where you might not want to freeze the browser while sending debugging information
back to your server.

afc358fb12 fix image loaded through the proxy hanging the preload process
images loaded through the proxy could hang the preload process if
they finish loading through the proxy but then fail to decode
and thus don't call the onload handler of the image object.

Note: This does not parse the % which would be good to delineate steps correctly, just a fix for an Exception.

73763c8114 rewrote image handling from using an array to an object
The image loading done in Preload.js used an array to store
image src and image object as 2 consecutive entries in that
array. Using the src as an index in a hash allows direct
instead of a linear search and also allows to store more data.

 * improved cleanup of images loaded with the proxy

 * this also adds a timeout for the image loading phase, after that
   running image requests are aborted and the rendering is started

7ee7d7fa67 It is possible for image tags not to have a 'src' (or background-image) attribute specified. This case currently crashes html2canvas. I know its an edge case but it bit me.

#### 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.

These are all of the available configuration options.
| Name | Default | Description |
| ------------- | :------: | ----------- |
| async | `true` | Whether to parse and render the element asynchronously
| allowTaint | `false` | Whether to allow cross-origin images to taint the canvas
| backgroundColor | `#ffffff` | Canvas background color, if none is specified in DOM. Set `null` for transparent
| canvas | `null` | Existing `canvas` element to use as a base for drawing on
| foreignObjectRendering | `false` | Whether to use ForeignObject rendering if the browser supports it
| imageTimeout | `15000` | Timeout for loading an image (in milliseconds). Set to `0` to disable timeout.
| ignoreElements | `(element) => false` | Predicate function which removes the matching elements from the render.
| logging | `true` | Enable logging for debug purposes
| onclone | `null` | Callback function which is called when the Document has been cloned for rendering, can be used to modify the contents that will be rendered without affecting the original source document.
| proxy | `null` | Url to the [proxy](/proxy/) which is to be used for loading cross-origin images. If left empty, cross-origin images won't be loaded.
| removeContainer | `true` | Whether to cleanup the cloned DOM elements html2canvas creates temporarily
| scale | `window.devicePixelRatio` | The scale to use for rendering. Defaults to the browsers device pixel ratio.
| useCORS | `false` | Whether to attempt to load images from a server using CORS
| width | `Element` width | The width of the `canvas`
| height | `Element` height | The height of the `canvas`
| x | `Element` x-offset | Crop canvas x-coordinate
| y | `Element` y-offset| Crop canvas y-coordinate
| scrollX | `Element` scrollX | The x-scroll position to used when rendering element, (for example if the Element uses `position: fixed`)
| scrollY | `Element` scrollY | The y-scroll position to used when rendering element, (for example if the Element uses `position: fixed`)
| windowWidth | `Window.innerWidth` | Window width to use when rendering `Element`, which may affect things like Media queries
| windowHeight | `Window.innerHeight` | Window height to use when rendering `Element`, which may affect things like Media queries
If you wish to exclude certain `Element`s from getting rendered, you can add a `data-html2canvas-ignore` attribute to those elements and html2canvas will exclude them from the rendering.

description: "Learn about html2canvas, how it works and some of its limitations"
nextUrl: "/getting-started"
nextTitle: "Getting Started"
---
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 or use the window configuration options to set a custom window size based on the `canvas` element:
```
await html2canvas(element, {
windowWidth: element.scrollWidth,
windowHeight: element.scrollHeight
});
```
The window 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
```javascript
import html2canvas from '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.
## Available proxies
- [node.js](https://github.com/niklasvh/html2canvas-proxy-nodejs)

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 ###
For more information and examples, please visit the <a href="http://html2canvas.hertzen.com">homepage</a> or try the <a href="http://html2canvas.hertzen.com/screenshots.html">test console</a>.

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.
