cordova
1

I been use this plugin for crop image but it can only crop image in square, and I don’t know how to crop in rectangle

Here is my code

takeThePhoto(pictureSourceType): Promise<any> {
	return this.camera.getPicture(
		{
			destinationType: this.camera.DestinationType.FILE_URI,
			mediaType: this.camera.MediaType.ALLMEDIA,
			sourceType: pictureSourceType, 
			encodingType: this.camera.EncodingType.JPEG,
			correctOrientation: true
		}
	).then(
      fileUri => {
        if (this.platform.is('android')) {
          fileUri = 'file://' + fileUri;
        }
        return this.crop.crop(fileUri, {quality:100});
      }, err => { } ).then(path => { 
          this.imgUrl = path
          console.log(path)
        }, err => { }
    );
  }

This is what it look like

Plugin: https://jamesssooi.github.io/Croppr.js/

in ts file:

ionViewDidLoad() { 
    this.croppr();
  }
croppr(){
       this.cropInstance = new Croppr('#croppr', {
          // options
        });  
    }
    cropprGetVal(){
      var newSrc
      var data:any = []
      data = this.cropInstance.getValue();
      let x = data.x
      let y = data.y
      let width = data.width
      let height = data.height
     
      var img = new Image();
      img.src = this.imgUrl;
      var canvas = document.createElement('canvas');
      var ctx = canvas.getContext('2d');
      canvas.width=width
      canvas.height=height
      ctx.drawImage(img, x, y, width, height, 0, 0, width, height); 
      console.log(canvas.toDataURL("image/jpeg"))
      this.imgCroppedUrl = canvas.toDataURL("image/jpeg")
    }

in html

<div *ngIf="imgUrl != null">
  <div  class="modal">
    <img id="croppr"  [src]="imgUrl" #imageSrc>
  </div>  
</div>
<ion-item *ngIf="imgCroppedUrl != null" >
    <img   [src]="imgCroppedUrl" #imageSrc style="width:100%;height:auto;">
</ion-item>
