Possible orientations of an image
Values are taken from the IFD tag Orientation (0x0112) in most cases but they can be
obtained from other metadata in the file.
Convert a u16 from the IFD tag Orientation (0x0112) into its corresponding
enum value
Convert orientation to an image flip operation tuple. The first field is
if x and y coordinates should be swapped (transposed). The second and
third field is horizontal and vertical flipping respectively. For a
correct result, flipping must be done before transposing.
Does the opposite of to_flips()
Convert orientation to the Tiff Orientation value
