Prevent user from cropping a photo with edges outside of the image boundary about rskimagecropper

[ruslanskorb]

If I understood you correctly, you are looking for a way to configure the bounces and bouncesZoom properties of RSKImageScrollView. By setting them to NO, it is possible to achieve the effect you want.

At the moment RSKImageCropper has no such functionality. But it is possible to add new properties bounces andbouncesZoom to RSKImageCropViewController, similar to the properties alwaysBounceHorizontal and alwaysBounceVertical.

viewController.avoidEmptySpaceAroundImage = YES;
viewController.bounces = NO;
viewController.bouncesZoom = NO;

If you get the chance to do this and open the PR, I'll be happy to add these changes to RSKImageCropper.

Hi thanks for the quick response. I noticed that property but it seems like it only prevents the mask from exceeding the image boundary after the user stops dragging the mask. If the user taps the submit button while the mask is still being dragged, it's possible for there to be empty space still as far as I can tell -- let me know if that's not the case.

Hi @matthewjsloane,

Thank you for the question!

You probably need the avoidEmptySpaceAroundImage property of RSKImageCropViewController. It determines whether the image will always fill the mask space. Default value is NO.
