; Selection to AnimationImage
; This script requires plug-in-gap-layers-run-animfilter (that is part of
; the gap Plugin-collection, available in the plugin registry)
;
; - 26.5.1999 hof: adapted for GIMP 1.1 Plug-in Interfaces
; - Takes the Current selection and saves it n-times (as multiple layers) in one seperate image.
; (base functions taken from Selection to Image ((c) by Adrian Likins adrian@gimp.org)
; - added number of copies and
; - optional { BG-FILL | TRANS-FILL }
; - if there was no selection at begin the selection is cleared at end
; - optional call of plug-in-gap-layers-run-animfilter
; (to create animation effects by applying any available PDB filter foreach copy
; (==layer) of the generated image
; with constant or varying values)
; - if we just copied some layers set the generated brush-image clean at end
