Hi, Is it possible to only operate on one subimage and still keep the rest untouched?
In my case I get EXRs from comp that have mattes as separate subimages in the EXR. I want to perform a colorconvert on the main subimage of the EXRs, but if I do so I lose the rest of the subimages: oiiotool /path/to/frame.exr --colorconvert linear AlexaV3LogC -o /path/to/out.exr By reading around on the mail list here, I then got inspired into trying this: oiiotool /path/to/frame.exr --subimage main --colorconvert linear AlexaV3LogC /path/to/frame.exr --subimage matte1 --siappendall -o /path/to/out.exr This will indeed create an EXR with the same number of subimages as before, but the "matte1" remains completely empty. Subimage "main" has in this case the channels "R, G, B, A" and "matte1" have the channels "red, green, blue, alpha". What did I do wrong? Is this possible? I have tried this in both 1.8.17 and 2.0.12. Thanks in advance, Andreas
