;
|
|
; This GIMP script_fu operates on a single Layer
|
|
; It blends the outline boarder from one to another transparency level
|
|
; by adding a layer_mask that follows the shape of the selection.
|
|
; usually from 100% (white is full opaque) to 0% (black is full transparent)
|
|
;
|
|
; The user can specify the thickness of the fading border
|
|
; that is used to blend from transparent to opaque
|
|
; and the Fading direction (shrink or grow).
|
|
;
|
|
; The outline is taken from the current selection
|
|
; or from the layers alpha channel if no selection is active.
|
|
;
|
|
; Optional you may keep the generated layermask or apply
|
|
; it to the layer
