thanks at first! I'l test your script if there ist some time. My handy way was: 1. create optimized palette 2. select by color 3. "flying layer" to new layer 4. extend layer to image extensions (important!!!) 5. rename the new layer to color or gis thema (eg. wather, street ...) again for each color 6. save as xcf for keeping the layers 7. delete all uninteressting layers 8. create b&w palette 1-bit (may be before step 6 but layers must/should be named right) 9. save as tiff (may be with lzw-compression or not) !!! binary tiff save had a bug in gimp 2.2 .. but works fine with my 2.3.14 !!! reload 6. again for each layer I'm not so good in programming and I do not know if my hady way could become a script an whitch would be better. > -----Ursprüngliche Nachricht----- > Von: saulgoode@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx > Gesendet: 27.06.07 17:20:44 > An: gimp-developer@xxxxxxxxxxxxxxxxxxxxxx > Betreff: Re: Doing an action for each color in an indexed color-palette > > Quoting Roberto Uhlig <Roberto.Uhlig@xxxxxx>: > > > Hello, > > has/knows anyone a script/plugin (an idea) to go color by color > > through an indexed color-palette and doing an action for each color? > > I'd like to create from a picture with an optimized color-palette > > with ca. 5-10 (may be 1-256) colors new layers or new pictures for > > each color in palette. > > Layer(s) or pictures must have the same extensions like the original picture. > > The new picture must be a black and white (1-bit) palette binary > > tiff for using in geo information systems as visible and invisible. > > I have written a script > (http://flashingtwelve.brickfilms.com/GIMP/Scripts/Temp/save-as-map-masks.scm) > which attempts to address your problem.
