How can I check to see if an RGB tiff has a specific color?
checkimg example.tif -color "0 255 0"
The images are 8k x 8k pixels.
I tried the following, but I stopped it at 600mb size. Was going to scan the output, but that seems to be too much processing.
convert example.tif out.txt

The XPM format is text (C source code) and starts with a color map, so you could restrict your search to the color map only. However, IM's convert seems to coerce the image into a 256-color colormap (while Gimp will produce a 100K-colors map if necessary). – xenoid – 2019-04-05T22:27:34.457
