24 This GM tests whether the image decoders properly decode each color
25 channel. Four copies of the same image should appear in the GM, and
26 the letter R should be red, B should be blue, G green, C cyan, M
27 magenta, Y yellow, and K black. In all but the JPEG version of the
28 image, the letters should be on a white disc on a transparent
29 background (rendered as a checkerboard). The JPEG image has a grey
30 background and compression artifacts.
