I would want to get some pixel color of the X screen the perl application is currently running on.

Im using perl-TK to generate the user interface, so maybe theres something useable there. The pixel I want to "read" is outside the user interface.

But is it possible to get the pixel color of a specific pixel, and hopefully without taking a screenshot and then using GD/ImageMagick because that would be pretty memory/CPU hungry.

Something like:

($r,$g,$b) = [somemodule]->pixel($x,$y);
