Hi, there, I am using Gimp-Perl v1.083 to manipulate the pixel data of an image. What I am confusing about is the data structure of the packed pixel data. For example, I can run the following perl code: $region = $drawable->get->pixel_rgn (0,0, 100,100, 1,0); $pixel = $region->get_pixel (5,7); # fetches the pixel from (5|7) print $pixel; # outputs something like # [255, 127, 0], i.e. in # RGB format ;) But how can I modify the components of this $pixel? For example, modify it to [255,127,1]? I have tried to treat it as an array or an array reference, but I failed. Any help is greatly appreciated. Xiaodi
