Getting started

Installation

npm install jquery-cropper jquery cropperjs

Include files:

<script src="/path/to/jquery.js"></script><!-- jQuery is required -->
<script src="/path/to/cropper.js"></script><!-- Cropper.js is required -->
<link  href="/path/to/cropper.css" rel="stylesheet">
<script src="/path/to/jquery-cropper.js"></script>

Usage

Initialize with $.fn.cropper method.

<!-- Wrap the image or canvas element with a block element (container) -->
<div>
  <img id="image" src="picture.jpg">
</div>

/* Limit image width to avoid overflow the container */
img {
  max-width: 100%; /* This rule is very important, please do not ignore this! */
}

var $image = $('#image');

$image.cropper({
  aspectRatio: 16 / 9,
  crop: function(event) {
    console.log(event.detail.x);
    console.log(event.detail.y);
    console.log(event.detail.width);
    console.log(event.detail.height);
    console.log(event.detail.rotate);
    console.log(event.detail.scaleX);
    console.log(event.detail.scaleY);
  }
});

// Get the Cropper.js instance after initialized
var cropper = $image.data('cropper');

Options

See the available options of Cropper.js.

$().cropper(options);

Methods

$().cropper('method', argument1, , argument2, ..., argumentN);

Events

$().on('event', handler);

No conflict

If you have to use other plugin with the same namespace, just call the $.fn.cropper.noConflict method to revert to it.

<script src="other-plugin.js"></script>
<script src="jquery-cropper.js"></script>
<script>
  $.fn.cropper.noConflict();
  // Code that uses other plugin's "$().cropper" can follow here.
</script>

Browser support

It is the same as the browser support of Cropper.js. As a jQuery plugin, you also need to see the jQuery Browser Support.
