Description

If I take one of the images generated by test_figureExportScripts.py and run channel offsets to shift the first plane by X=1, Y=1 then I get a surprisingly different image. This may be more a curiosity than a bug.

This is because the original image has all Red channels but the new image has Red, Green, Blue channels.
Currently the script does not try to set colours on the new image channels.

Ah, perhaps this becomes an RFE for channel property preservation? I don't know if that's simple or if there is enough to it that Duplicate could be useful. I also don't know if anybody would appreciate the effort: I am guessing it's not been asked for, so feel free to close this ticket if it's unlikely to ever reach the top of the to-do list!
