- Install with [NPM](https://npmjs.com): `npm install cropper`.
- Install with [Bower](https://bower.io): `bower install cropper`.
### Installation
Include files:
```html
<script src="/path/to/jquery.js"></script><!-- jQuery is required -->
<link href="/path/to/cropper.css" rel="stylesheet">
<script src="/path/to/cropper.js"></script>
```
The [cdnjs](https://github.com/cdnjs/cdnjs) provides CDN support for Cropper's CSS and JavaScript. You can find the links [here](https://cdnjs.com/libraries/cropper).
### Usage
Initialize with `$.fn.cropper` method.
```html
<!-- Wrap the image or canvas element with a block element (container) -->
<div>
<img id="image" src="picture.jpg">
</div>
```
```css
/* Limit image width to avoid overflow the container */
img {
max-width: 100%; /* This rule is very important, please do not ignore this! */
}
```
```js
$('#image').cropper({
aspectRatio: 16 / 9,
crop: function(e) {
// Output the result data for cropping image.
console.log(e.x);
console.log(e.y);
console.log(e.width);
console.log(e.height);
console.log(e.rotate);
console.log(e.scaleX);
console.log(e.scaleY);
}
});
```
#### FAQ
##### How to crop a new area after zoom in or zoom out?
> Just double click your mouse to enter crop mode.
##### How to move the image after crop an area?
> Just double click your mouse to enter move mode.
##### How to fix aspect ratio in free ratio mode?
> Just hold the `shift` key when you resize the crop box.
##### How to crop a square area in free ratio mode?
> Just hold the `shift` key when you crop on the image.
#### Notes
- The size of the cropper inherits from the size of the image's parent element (wrapper), so be sure to wrap the image with a **visible block element**.
> If you are using cropper in a modal, you should initialize the cropper after the modal shown completely. Otherwise, you will not get a correct cropper.
- The outputted cropped data bases on the original image size, so you can use them to crop the image directly.
- If you try to start cropper on a cross-origin image, please make sure that your browser supports HTML5 [CORS settings attributes](https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_settings_attributes), and your image server supports the `Access-Control-Allow-Origin` option (see the [HTTP access control (CORS)](https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS)).
#### Known issues
- [Known iOS resource limits](https://developer.apple.com/library/mac/documentation/AppleApplications/Reference/SafariWebContent/CreatingContentforSafarioniPhone/CreatingContentforSafarioniPhone.html): As iOS devices limit memory, the browser may crash when you are cropping a large image (iPhone camera resolution). To avoid this, you may resize the image first (below 1024px) before start a cropper.
- Known image size increase: When export the cropped image on browser-side with the `HTMLCanvasElement.toDataURL` method, the size of the exported image may be greater than the original image's. This is because the type of the exported image is not the same as the original image's. So just pass the type the original image's as the first parameter to `toDataURL` to fix this. For example, if the original type is JPEG, then use `$().cropper('getCroppedCanvas').toDataURL('image/jpeg')` to export image.

## Options
You may set cropper options with `$().cropper(options)`.
If you want to change the global default options, You may use `$.fn.cropper.setDefaults(options)`.
### viewMode
- Type: `Number`
- Default: `0`
- Options:
- `0`: the crop box is just within the container
- `1`: the crop box should be within the canvas
- `2`: the canvas should not be within the container
- `3`: the container should be within the canvas
Define the view mode of the cropper.
### dragMode
- Type: `String`
- Default: `'crop'`
- Options:
- `'crop'`: create a new crop box
- `'move'`: move the canvas
- `'none'`: do nothing
Define the dragging mode of the cropper.
### aspectRatio
- Type: `Number`
- Default: `NaN`
Set the aspect ratio of the crop box. By default, the crop box is free ratio.
### data
- Type: `Object`
- Default: `null`
The previous cropped data if you had stored, will be passed to `setData` method automatically.
### preview
- Type: `String` (**jQuery selector**)
- Default: `''`
Add extra elements (containers) for previewing.
**Notes:**
- The maximum width is the initial width of preview container.
- The maximum height is the initial height of preview container.
- If you set an `aspectRatio` option, be sure to set the preview container with the same aspect ratio.
- If preview is not getting properly displayed, set `overflow:hidden` to the preview container.
### responsive
- Type: `Boolean`
- Default: `true`
Re-render the cropper when resize the window.
### restore
- Type: `Boolean`
- Default: `true`
Restore the cropped area after resize the window.
### checkCrossOrigin
- Type: `Boolean`
- Default: `true`
Check if the current image is a cross-origin image.
If it is, when clone the image, a `crossOrigin` attribute will be added to the cloned image element and a timestamp will be added to the `src` attribute to reload the source image to avoid browser cache error.
By adding `crossOrigin` attribute to image will stop adding timestamp to image url, and stop reload of image.
### checkOrientation
- Type: `Boolean`
- Default: `true`
Check the current image's Exif Orientation information.
More exactly, read the Orientation value for rotating or flipping the image, and then override the Orientation value with `1` (the default value) to avoid some issues (#120, #509) on iOS devices.
Requires to set both the `rotatable` and `scalable` options to `true` at the same time.
**Note:** Don't trust this all the time as some JPG images have incorrect (not standard) Orientation values.
> Requires [Typed Arrays](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray) support ([IE 10+](http://caniuse.com/typedarrays)).
### modal
- Type: `Boolean`
- Default: `true`
Show the black modal above the image and under the crop box.
### guides
- Type: `Boolean`
- Default: `true`
Show the dashed lines above the crop box.
### center
- Type: `Boolean`
- Default: `true`
Show the center indicator above the crop box.
### highlight
- Type: `Boolean`
- Default: `true`
Show the white modal above the crop box (highlight the crop box).
