Hello and best thanks first, but it doesn't work correct on my xp-pc with gimp GIMP 2.3.10. After private consultation with saul some testing and some changes for windows (backslash \) now it works fine. Essential change is, that saul's ;; (set! blue (fmod (aref color-map (+ 2 index)) 256)) doesn't work. aref brings sometimes negative eg. -51 values. In that case you have to ad 256 to become the realy color-value for blue. So I implementet (set! blue (aref color-map (+ 2 index))) (if (< blue 0) (set! blue (+ blue 256))) and it does his job. I've tested it only under WINXP with Gimp 2.3.10 and also with 2.2.11.
Because of a bug in save-tiff-plugin in gimp 2.3.x (I din't know which was the fix) it isn't possible to save black-white (1bit) indexed with older gimp's. In my 2.3.10 it works fine. Where can I find Informations about internals of the color-map int8array data storage, because I found that negative integer values?
