Good stuff--I have slightly different need. I am wondering if someone looking at this thread has already figured this "easier" version out. I don't want to transform the data--I just want to set the same rotation flag that Apple uses in its stored photos. If you process the nominal data it appears that the data is rotated landscape vs. portrait (in the nominal position). I believe imageOrientation is the key (UIImage) but that particular data member is read only according to the docs. I haven't figured out how to set the same orientation in the output images. Anybody have an idea?
