Re: [Question #156978]: Create a comparison image

 

Question #156978 on Sikuli changed:

    Status: Open => Answered

RaiMan proposed the following answer:
Sikuli's search engine does not know or evaluates image differences in your sense (areas of the 2 compared images that differ).
The returned score value is only some relative measure for the probability, that the whole probe and the whole reference image are identical.

With the used algorithms, a score above 0.7 normally means found/equal
and meets our expectations of equality. But in some cases (weakness of
the current algorithm) even a score of 1.0 does not mean equality (e.g.
some color and/or gray scale cases).

So in your case, Sikuli does not have a built in solution for that.

But it should be rather easy, to integrate calls to imagemagick to let
it show the differences in the relevant cases.
