    Re: Image crop

    Reasonably easy to do in RC6 & Cairo (if you're willing to use it) because it can do a lot of the math for you converting between device and image coordinates.

    Here's a quick example project I made (comments by Gemini, edited by me). I'm sure Olaf could do it even more efficiently if he happens by and has time to provide an even tighter sample (there is a cControlPoint class in RC6 that I haven't had a chance to try yet that might make it possible to remove all the HitTest a Resize Handle stuff in my demo)
