When processing a series of files in script-fu,
I'm trying to do the following:
for each file name:
Create an image by reading it in.
(set! orgImg (car (file-ufraw-load ...
Create another image by duplicating the input image and manipulating it.
(set! newImg (car (gimp-image-duplicate orgImg)))
(gimp-image-scale newImg wid ht)
(plug-in-unsharp-mask RUN-NONINTERACTIVE newImg newImg ...
Write the new image out.
(file-jpeg-save ... newImg ...
Since I'm done with the newly created image, I did a
(gimp-image-delete newImg)
Continuing on,
if I try to re-use that variable to create another image
from the original image
and try to manipulate it, I get an error after a bit:
(set! newImg (car (gimp-image-duplicate orgImg))) ; doesn't complain
(gimp-image-scale newImg wid ht) ; doesn't complain
(plug-in-unsharp-mask RUN-NONINTERACTIVE newImg newImg ...
Error: Procedure execution of plug-in-unsharp-mask failed on invalid input
arguments: Procedure 'plug-in-unsharp-mask' has been called with an invalid ID
for argument 'drawable'. Most likely a plug-in is trying to work on a layer
that doesn't exist any longer.
If I comment out the
gimp-image-delete
it works fine.
Can someone explain to me what is going on?
(Using gimp 2.6)
Thanks,
Gary
