ember-cropperjs
This addon provides a wrapper around Cropper.js as well as two yielded components for handling events and programatically calling methods on the cropper instance.
Installation
ember install ember-cropperjs
Usage
// app/controllers/application.ts
import Controller from '@ember/controller';
import { debounce } from '@ember/runloop';
import { action } from '@ember/object';
export default class ApplicationController extends Controller {
_updateFileBlob(cropper) {
return cropper
.getCroppedCanvas({
// any additional options
maxWidth: 512,
maxHeight: 512,
})
.toBlob((blob) => {
// do something with the blob:
// common examples include `blob.readAsDataURL()` or `blob.readAsArrayBuffer()`
});
}
@action crop(cropper) {
// debounce is optional
debounce(this, this._updateFileBlob, cropper, 100);
}
}
Note: Any options available from Cropper.js are available to be passed in to the options hash. There seems to be an issue with Cropper processing Ember's Empty Object, so the components/image-cropper.js
file copies the options object as a work around.
