However, I am designing a procedure and software for some optical equipment tests, which would be performed by multiple users on their own computers; thus I am looking for a "gimp generic" solution.
One such test consists of between 50 and 100 points pixel coordinates from a single image file being recorded in a text file (which is later processed in other software). Gimp (or similar program) is quite useful because it is simple to quickly change image content to (for instance) monochrome green, so that the black cross-shaped cursor stands out quite well.
I was actually expecting that "measure tool" would offer such functionality and that, despite my efforts, I was just unable to figure out how to do it.
Thank you all for helpful comments.
(BTW, where can one just look at the Gimp source code?)
