I have multiple pictures that are look alike, they're all black and differ only in the one dot of the screen, I want to combine them in one picture so I can see all the dots in one picture. How can I do this using something like ImageMagic? I don't want to use something with gui bc there are a lot of pictures, but they're not that big, so it would be easier to do this with terminal utility. I tried
composite -blend 50 *.png res.png
but it didn't work out.
UPD: Now I understood that it doesn't work because it works only with two images, how do I do these to all the images that matches the regular expression like somth*.png?
