(should be simple enough, but…)

have an image with red only & alpha: info = 2 bytes/pixel, 2 planes
C shows as simply “C” as opposed to “C {r g b}”

I'd like to cp red into green and blue; thought I could use Channel Copy COP but don't see color components in Target and Source so it needs to be processed.

I admit I can't get PRISMS (ICE) out of my head… ops:



To get around it I used the red only image to Multiply a white Color COP to boost up to 4 bytes/pixel and then used the Channel Copy COP. It seems more convenient for the Channel Copy COP to be able to do the cp straight out. It's not a huge deal of course but what do developers think?

Rename C to M with a Rename COP, then use Channel Copy with Target=C and Source=M. You can use a Delete COP afterward to delete the M plane if it you like (though it will cause no extra cooking or memory). There is currently no COP to promote planes to higher vector types.

“twod”, your solution is much more elegant! I like it.

My thanks,
