I have written a script (http://flashingtwelve.brickfilms.com/GIMP/Scripts/Temp/save-as-map-masks.scm) which attempts to address your problem. I do not know how to save 1-bit TIFFs and so my script saves the files as RGB-mode black-and-white PNGs (I know Indexed would be smaller, but I was lazy). From the comments in the script: ;; Saves a PNG file for each color of an Indexed image where that ;; color is replaced by white and the rest of the image is black. ;; The PNG's filename is derived from the name of the bottom ;; layer of the original Indexed image. The RGB colors are ;; appended to this name, separated by hyphens. ;; An example of an output filename would be ;; "Background-10-242-79.png". ;; ;; The files (one for each indexed color) are saved in the same directory as ;; the original image (or to the GIMP invocation directory if a ;; new image). _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
