|
; Change the colourmap of an image to the colours in a specified palette.
|
|
; Included is script-fu-make-cmap-array (available for use in scripts) which
|
|
; returns an INT8ARRAY containing the colours from a specified palette.
|
|
; This array can be used as the cmap argument for gimp-image-set-cmap.
