How to get image url from cropit image cropper library?

Question

In image cropping library "cropit" everything works fine except it does not gives the valid cropped image url.The resulting url id invalid when I try to open it in browser. Even in the official doc example it opens invalid url. How to get correct cropped image url.

$imageCropper.cropit('export', {
    type:'image/jpeg',
    quality: .9,
    originalSize:true
      });

This code gives invalid url. Any other way please.
