Well, to make it simple,
I want to replace the
yellow pattern that have a line over them in this image:
=> Pattern to replace:
with this one:
I'm not quite sure IF this is possible, however as no other tools exist to do this I'm betting my hope on ImageMagick so it will help me (once again).
Thanks in advance for awesome answers.

A compare with subimage-search will find the two locations, expressed as a "match score" image with brightest points (probably pure white in this case). The location of these brightest points are the coordinates to put the replacement image.

since I don't actually get the usage of those "bright points".
Mind posting an example ?

Windows script:
Code: Select all
set SRC="22 HP+200.png"
set SUB=test.png
set REP="03 (yellow) +-Part.png"
"%IMG%compare" -metric RMSE %SRC% %SUB% -subimage-search found.png
This outputs:
It has found a match at coords (39,37). In your script, paste the replacement at that position. Then repeat until the number in brackets is no longer (0).

what would have to be added to this script so it will automatically repeat a paste till a match is no longer found ?

How can I modify the script to actually use these coordinates right now and paste the other images in ?
