            Description

            A community member has posted a file that contains three jpeg images that we having trouble distinguishing YCbCr and Cmyk colour spaces. We are incorrectly treating it as Cmyk instead of YCbCr.

            I've verified that the images contain the APPE PhotometricInterpretation valued as RGB which we might be able to use as a means to determine the correct 3 component colour mode.

              I've added a code snippet that searches for the Adobe data in the JPEG meta data and returns the value transform key. A value of 1 is YCbCr and 2 is YCCK,
