MFMailComposeViewController image orientation http://stackoverflow.com/questions/20204495/mfmailcomposeviewcontroller-image-orientation to rotate it so it will appear correctly. If you capture an image in portrait mode image.imageOrientation will return UIImageOrientationRight. This tells displaying software that it needs to rotate the image 90 degrees so it will display correctly. Be clear that.. to screen self imagePickerControllerRelease picker free the picker object If we shoot portrait gImage arrives with UIImageOrientationRight and width 3264 and height 2448. If we shoot landscape gImage arrives with UIImageOrientationUp and width 3264 and height.. rotate the underlying stored image according to its orientation property. For a UIImage with an orientation of UIImageOrientationRight it will physically rotate the UIImage so it ends up as 2448x3264 and it will strip away the orientation property so it is..
