Opaque only the first image in stack

[troyd1]

Is there a way to make the opaque and other processing options only work on the first image in the stack? I build an image by reading an image, doing an opaque and then a composite multiple times. It changes the current image as well as the previous one that will be composited. I tried putting parens () around the last image and the opaque command, but it did not help.

Showing you command would probably help.

You say you want to work on the first image then you say you put () around the last image which does not seem to make sense.

Sorry, I should have posted an example. My issue was that I had the parens() up against the text. ie. (img.png -fill red -opaque black) instead of ( img.png -fill red -opaque black ). Works perfectly now.
