A simple, fast autocrop library which automagically crops the image. The cropping related functions are based on autocrop.js . This library offloads image processing work from main thread to workers using workerpool.

Demo site:

Install
-------

``bash
$ npm install autocrop-worker
`

Usage
-----

$3

`javascript
import autocrop from 'autocrop-worker'
autocrop(, (target_image_element), (options));
`

$3


`javascript
// workerpool need to be loaded before autocrop-worker.min.js


...

`

If target_image_element is set null, it will replace original_image_element with the cropped result.

Parameter
---------

`javascript
const autoCropDefaultOptions = {
bgColor: '#FFFFFF', // Background color.
alphaTolerance: 20, // Pixels that are transparent than this value are considered transparent.
colorTolerance: 20, // Pixels similar to the background color are considered as the background.
invertTolerance: 0.90, // Invert the image if most of non-transparent pixels are background color.
margin: '2%', // Margin
allowInvert: true, // Allow invert if needed.
marker: 'cropped', // Add a marker attribute to prevent duplicated cropping.
version: boolean|string /* Defaults to current timestamp. Used for avoiding crossorigin taint issues due to previous cache.
Set it to false for dataURL and blobs */
};
