Presenting an image cropping interface

Question

I\'m trying to engineer a UI for cropping images in iphone OS and suspect I\'m going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pa

Answer 1

I have found that often a better UI for cropping results if you think of manipulating the position and size (and even rotation) of an image underneath a simple, immovable mask or cropping rect rather than trying to move a mask or cropping rect on top of an unmoving image. This is especially true of you always want the cropped image to have a preset proportion and orientation.

For record's sake - A ready made component on Cocoa Controls
