mask.inverted() doesn't seem to produce the desired effect

[Xcoder89]

Trying to implement a erase background feature using the transparent view mode so that the result image would be obtained by inverting the mask. But the mask.inverted().cutout() doesn't seem to produce the desired result.

@Xcoder89 Thanks for reporting the issue. Can you tell us more about this? What is your desired result and what is the function actually outputs?

If you invert the mask the image is not cutout. Any help please?

same problem here.
I drag to remove background and confirm.
But the result is background.
So I did mask.inverted().cutout(image, false).
But it removes nothing.

@AdamWorld This should help you :)

- (UIViewController *)tcMaskViewWillPushViewControllerWithMask:(TCMask *)mask image:(UIImage *)image {
  // Broken on TinyCrayon 5.0.1
  //TCMask *invertedMask = [mask inverted];
  NSMutableArray *newData = [NSMutableArray arrayWithCapacity:mask.data.count];
  for (NSNumber *n in mask.data) {
    [newData addObject:@(255 - n.unsignedIntegerValue)];
  }
  
  TCMask *invertedMask = [[TCMask alloc] initWithData:newData size:mask.size];
  UIImage *outputImage = [invertedMask cutoutWithImage:image resize:true];
}
