I’m using G’MIC to make montages of photos for a photo book. I have written a custom command that accepts a list of images to arrange on a page. It uses the image command to place each one at the desired place on the page.
Some of my images have transparency or alpha and I’d like to overlay them based on that transparency. Do the opacity-related parameters of the image command provide that capability?
I think the following steps would be equivalent:
- duplicate the background
- crop the duplicate background to the area being overlaid
- blend the cropped piece and the image with transparency/alpha
- image the blended piece back into the background page
OK, in retrospect, that’s not too hard. Is that just the correct way to do this in G’MIC?
