Hello, can someone please explain me how to use the result from (gimp-drawable-get-pixel) inside the scheme script? The function gives me result like (4 #4"1d1d1dff"). How do I convert this result to more friendly form like '(255 127 0), so I could make some calculations with it? The second question is: What is the best way to calculate how one pixel match the other pixel by the color (result between 0-no match at all and 1-same color)? A simple scheme example would be great. Thank you for your answer. best regards, Zoran Bosnjak
