Support flip (mirroring) on rotate #3

Open automata opened 9 years ago

automata commented 9 years ago

For now we only support some of the EXIF Orientation values, those that do not involve flipping. (We'll need flip support on Imgflo's preprocess graph too)

Do any cameras use those values?

AFAIK 1, 3, 6 and 8 are used by many cameras, as expected. But I do not know about uses of other values... maybe by digital scanners?

I think this issue only makes sense to maintain compatibility with the full EXIF spec.
