You're awesome! Ill work with this today, and see where I get. In addition to changing the channel names I also wanted to be able to combine the channel data from the rgb channels from each layer into one. In python I just created a dictionary, grouped the rgb channels and used array to convert them. So (customlayer.red, customlayer.blue, customlayer.green) became (newlayername.customchannelname(combined pixel data from red, green, blue)). In C++ it doesn't seem seem as simple. Do you have any suggestions for doing the same in C++?
