Get main image not from input field

[romangusiev]

Hey, iI'm trying to crop image but not picking it up from input field, but getting it from base64 string.
So I'm doing like this - $scope.dataUrl = newDataURL; - and it starts showing up the image. But when I try to get cropped image - it does not work, because calling Cropper.crop($scope.cropperFile, $scope.cropperData).then(Cropper.encode) means that I have to have file picked in input. But it comes from my base64 string, not from input.
How can I set image from string and get cropped image then....
