Settings

• canvasWidth:number - Canvas DOM Element width
• canvasHeight:number - Canvas DOM Element height
• width:number - Crop Width
• height:number - Crop Height
• minWidth:number - Minimum crop Width
• minHeight:number - Minimum crop height
• croppedWidth:number - Resulting image width
• croppedHeight:number - Resulting image height
• touchRadius:number - (default: 20) Touch devices radius for the corner markers
• centerTouchRadius:number (default: 20) - Touch devices radius for the drag center marker
• minWithRelativeToResolution:boolean - (default: true) By default the resulting image will be cropped from original image. If false, it will be cropped from canvas pixels

  • strokeColor:string - box/ellipsis stroke color
• allowedFilesRegex:RegExp - (default: /.(jpe?g|png|gif)$/i) - Regex for allowed images
• preserveSize:boolean - will not scale the resulting image to the croppedWidth/croppedHeight and will output the exact crop size from original
• fileType:string - if defined all images will be converted to desired format. sample: cropperSample.fileType = 'image/jpeg'
• compressRatio:number (default: 1.0) - default compress ratio
• dynamicSizing: (default: false) - if true then the cropper becomes responsive - might introduce performance issues on resize
• cropperClass: string - set class on canvas element
• croppingClass: string - appends class to cropper when image is set (#142)
• resampleFn: Function(canvas) - function used to resample the cropped image (#136); - see example #3 from runtime sample app
• cropOnResize:boolean (default: true) - if true the cropper will create a new cropped Image object immediately when the crop area is resized
• markerSizeMultiplier:number (default: 1) - A variable that controls the corner markers' size
• showCenterMarker:boolean (default: true) - if true, the drag center marker is visible
• keepAspect:boolean (default: true) - if true, the aspect ratio of width and height of the crop window is retained during resizing

Customizing Image cropper

Replacing component file input:

1<div class="file-upload">
2    <span class="text">upload</span>
3    <input id="custom-input" type="file" (change)="fileChangeListener($event)">
4</div>
5<img-cropper #cropper [image]="data" [settings]="cropperSettings"></img-cropper>
6<br>
7<span class="result rounded" *ngIf="data.image" >
8    <img [src]="data.image" [width]="cropperSettings.croppedWidth" [height]="cropperSettings.croppedHeight">
9</span>

1data:any;
2
3@ViewChild('cropper', undefined)
4cropper:ImageCropperComponent;
5
6constructor() {
7    this.cropperSettings = new CropperSettings();
8    this.cropperSettings.noFileInput = true;
9    this.data = {};
10}
11
12fileChangeListener($event) {
13    var image:any = new Image();
14    var file:File = $event.target.files[0];
15    var myReader:FileReader = new FileReader();
16    var that = this;
17    myReader.onloadend = function (loadEvent:any) {
18        image.src = loadEvent.target.result;
19        that.cropper.setImage(image);
20
21    };
22
23    myReader.readAsDataURL(file);
24}
