ios6 - Image resizing not working properly in IOS 7 -

Curious to know that my simple image resizing code is ok for 2 different PNGs of the same image Not working from I am getting this image from 2 different masked frames to fix one of the empty other functions.

  UIGraphicsBeginImageContext (CGSizeMake (320, 320)); [Mascade Image DrawRight: CGRactack (0, 0, 320, 320)]; UIImage * imageThumb2 = UIGraphicsGetImageFromCurrentImageContext (); UIGraphicsEndImageContext ();  

Always use UIGraphicsBeginImageContextWithOptions (size , NO, 0. F)
