UIImage orientation problem

Question

Hello guys!

Is there a way to set manually the orientation of UIImage? Or create with orientation or somehow?

Thanks!

This is a pretty esoteric thing to want to do. Are you sure there isn't a simpler way to do what you want? (Such as modifying the transform property on the UIImageView showing the image.)

To make sure the UIImage had a particular orientation, you'd have to fiddle with the Exif tags before loading the picture. Open the file, modify the tags, save it, then read it. You can check out the iphone-exif library for inspiration, but probably need to expand on it.
