IDLgrImage and the channel keyword [message #90167]

All,

Has anyone figured out how to use the channel keyword for IDLgrImage?

If you try this

file = 'E:\Program Files\Exelis\IDL84\examples\data\rose.jpg'
im = read_image(file)
xobjview, obj_new('IDLgrImage',im, channel='ff0000'x)

What I expect to see is a red channel image, but instead I see cyan which is a combination of green and blue. So it is almost acting like a color subtraction. But if you try other hex combinations they don't work like subtractions either.

Any ideas????
