Answer 1

Using the code given in Link : http://www.hive05.com/2008/11/crop-an-image-using-the-iphone-sdk/

Instead of using CGRect and CGContextClipToRect Try using CGContextEOClip OR CGContextClosePath

Though i havnt tried this... But i have tried drawing closed path using CGContextClosePath on TouchesBegan and TouchesMoved and TouchesEnd events.

Hope this can give more insight to your problem...
