Hi, forks.

Here is a script. this copy a selection of the active layer and paste it as new layer with its opacity
made by Ankh (thank you, Ankh in #gimp, irc.gimp.org)

but there is a problem. size of the new layer is not its own size, is the same with the image. so I tried to fix this script, but I failed. T_T

please, fix it. and I want one more thing.

I'd like to add a function for pasting a content of clipboard as new layer. I failed, either -_-

these are very simple function, and I can do using some menus and keyboard shortcuts.
but sometime I need and repeating 2-3 steps makes me mad. please help me.

; Define the Function (define
(copy-paste-new-layer
inImage
inDraw)

; Declare the Variables (let*
((theHeight (car (gimp-image-height inImage))) (theWidth (car (gimp-image-width inImage))) (theFloatingSelection) ; an undefined variable to be defined below. (theType (car (gimp-drawable-type-with-alpha inDraw))) ; returns the drawables' type with an Alpha Channel (theSelection) ; undefined variable to contain the selected area in the image.
(theResult) ; undefined variable created below to hold the contents of the Copied Layers
(theOpacity (car (gimp-layer-get-opacity inDraw))) ; for layer opacity )

; Begin Undo Group
(gimp-image-undo-group-start inImage)

; Copy the selection from the current layer (gimp-edit-copy inDraw)

; Get the selected area in the image and save it to a channel (set! theSelection (car (gimp-selection-save inImage)))

; Create a new layer called "Cpoied Layer" to hold the pasted selection (set! theResult (car (gimp-layer-new inImage theWidth theHeight theType "Copied Layer" theOpacity NORMAL-MODE)))

; Fills theResult Layer (aka Copied Layer) with transparent fill (gimp-drawable-fill theResult TRANSPARENT-FILL)

; Adds theResult Layer to the active image (gimp-image-add-layer inImage theResult 0)

; Defines theFloatingSelection variable as containing the pasted layer and keeping the selection active (set! theFloatingSelection (car (gimp-edit-paste theResult FALSE)))

; Anchor theFloatingSelection to theResult (gimp-floating-sel-anchor theFloatingSelection)

; Reload the original selection (theSelection) (gimp-selection-load theSelection)

; Delete the channel holding the original selection (theSelection) (gimp-image-remove-channel inImage theSelection)

; End Undo Group (gimp-image-undo-group-end inImage))
