Description

Hi All,
I want to create a sequence of images, where each image contains only the changed pixels or transparent from previous frame to the current frame like the bunny sample in the OptimizeTransparency but not on gif animation but 2 jpgs. Is the a sequence of IM commands I can use to do this?

Thanks

Use the same command. From two input images that are the same size:

magick in1.png in2.png -layers OptimizeTransparency -delete 0 x.png

Any pixels that are the same become transparent. Changed pixels will be copied from the second input.

Exactly what i wanted thank you @snibgo, but it didnt work as good as i had hoped, until i added -fuzz 50%
eg:
magick 1.jpg 2.jpg -fuzz 50% -layers OptimizeTransparency -delete 0 diff.jpg
