1) How do I create an image with an alpha channel (and set the value of the alpha channel)? This is specifically so I can test alpha channel handling in Gimp-print. Specifically, I want to move the alpha channel handling (and the color map handling, but that's a lot easier) out of libgimpprint and into the plugin. 2) It appears that thumbnail images (via gimp_image_get_thumbnail_data) always contain an alpha channel (unfortunately, this isn't really what I want for (1)). Is there a reason this is the case, or am I missing something? -- Robert Krawitz <rlk@xxxxxxxxxxxx> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@xxxxxxxxxxxx Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton
