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