Resize a UIImage

Here's a really easy one. Resize a given UIImage that you've loaded in the following manner:

CGSize newSize = CGSizeMake(228.0, 228.0);

UIGraphicsBeginImageContext( newSize );

[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];

UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
