Hello, I'm having some trouble using oiiotool's copy channel operator. It might be user error but I wanted to check and see if it's intended behavior. I've only glanced at the code so far.
My test image is a PNG (4-channel RGBA), but only has information in the Alpha. When attempting to copy the Alpha into the other 3 channels and write out an RGB image (no Alpha), I get black. Imagemagick's 'convert' did what I expected. invoked as: oiiotool input.png --ch "R=A,G=A,B=A" -o output.png I also tried using the numeric channel labels to no avail. -sp
