Is the UIImage method:
+ (UIImage *)imageWithCGImage:(CGImageRef)imageRef scale:(CGFloat)scale orientation:(UIImageOrientation)orientation
cropping the original image or just rotating it?
Is there a way to display such image without having to display it in my app user interface ?
thanks
No, is not going to be cropped, just rotated and scaled by that size:
UIImage Reference
And, about how to display it without “displaying” it, maybe is a good idea to put the hidden parameter to YES, or set the alpha to 0.0
