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 result is a list: Array-length and the array. You can access the elements of the array via (aref array index)

But keep in mind, that processing all pixels of an image with (gimp-drawable-get-pixel) is *slow*. You might want to use gimp-perl or write an plugin in C.

Bye, Simon

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
