### 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 ###

| 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.

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.
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.
