Hi,
starting from a script posted on this list I wrote the one below that applies colorize tool to a group of files. The script can be called from the menu, but when I try to run it a second time, the item in the menu becomes grey and I have to refresh the scripts to run it again. Someone can help me to find the problem? Thanks, J.

;; batch-convert-colorize.scm -- convert a set of files to index ;; simple batch script for GIMP 2.2
;;
;; call it from the command-line using a line like the following: ;; gimp -i -b "(script-fu-batch-convert-index \"/home/user/images\" \"/*.png\" 180 50 0 )" "(gimp-quit 0)" ;; or from menu xtns -> script-fu -> Batch -> Colorize ;;

(define (script-fu-batch-colorize dir pat_file hue saturation lightness) (set! pattern (string-append dir pat_file)) (let* ((filelist (cadr (file-glob pattern 1)))) (while filelist
(let* ((filename (car filelist)) (image (car (gimp-file-load RUN-NONINTERACTIVE filename filename))) (drawable (car (gimp-image-get-active-layer image)))) (gimp-colorize drawable hue saturation lightness) (gimp-file-save RUN-NONINTERACTIVE image drawable filename filename) (gimp-image-delete image)) (set! filelist (cdr filelist)))))
