command line help

Version: ImageMagick 7.0.7-28

I need to compare 2 png files. And a file needs to chop an edge.
convert base.png -gravity EAST -chop 6x0 base.png
compare -metric AE clean.png base.png result.png

I would like to combine into one command line:
compare -metric AE clean.png \( base.png -gravity EAST -chop 6x0 \) result.png

But get error:
compare: unrecognized option `-chop'

I was using -crop and it worked without problem. So I thought changing to -chop should be no problem.

compare does not allow such. But you can use convert

Code: Select all

magick clean.png \( base.png -gravity EAST -chop 6x0 \) -metric AE -compare +write result.png -format "%[distortion]" info:

See https://imagemagick.org/script/command- ... hp#compare

P.S. You can request that -chop be added to compare in the Developers Forum. But that may or may not get done quickly.

Also note that for IM 7, it would be magick compare and not just compare. compare alone is for IM 6.
