Re: [Oiio-dev] Shuffle channels of two images
I think something like: oiiotool A.exr --ch R B.exr --ch B --chappend A.exr --ch G --chappend --chnames R,G,B -o mix.exr To break down what that means, * read A, take just its R channel * read B, take just its G channel * Append channels of the the top two images, yielding A.r,B.g on the top of the stack * read A again, take just its B channel * Append the channels of the top two images, now you have A.r,B.g,A.b * Force new channel names R,G,B just in case they carry their old names or got confused * Output to mix.exr > On Feb 13, 2020, at 10:23 AM, Jovce Malakovski wrote: > > Hi, > Is it possible with the command line tool (oiiotool) to shuffle the rgb > channels like > R from image A > G from image B > B from image A? > The current command --ch supports swapping channels of a single image, but is > it possible with two images?

[Oiio-dev] Shuffle channels of two images
Hi, Is it possible with the command line tool (oiiotool) to shuffle the rgb channels like R from image A G from image B B from image A? The current command --ch supports swapping channels of a single image, but is it possible with two images? Or is there some other command that can do this?
