Compare specific region in an image

[fmw42]

Perhaps the region you specified covers that area also. Make sure it does not.

Look at an output image create by

Code: Select all

convert \
\( ActivityScreenError1.png -size 1080x1925 xc:black -geometry +205+77 -compose over -composite \) \
\( ActivityScreenError.png -size 1080x1925 xc:black -geometry +205+77 -compose over -composite \) \
miff:- | compare -metric PAE - compare.png

To see where they differ.
