Pixelchecksum

[Christoph_]

I wonder if there is a way to make a pixelchecksum of a certain area, but only of pixels that match a certain color criteria /eg. find all yellow pixels in Area 1).

Else it would be rather handy to have a pixelsearch that returns the locations of all (color)pixels found in a certain area.

Is there any way ?

If one wonders what I want to do with it: OCR.

You should for this write your own pixelchecksum, because such a function does not exist yet.
