Hi,
as totally new both on script-fu and in this group I'll try not to stress your
patience.
I made a script to downscale all images in a directory:
(define (autoskaler pattern width height)
(let* ((filelist (cadr (file-glob pattern 1))))
(while filelist
(let* ((filename (car filelist))
(image (car (gimp-file-load RUN-NONINTERACTIVE
filename filename)))
(drawable (car (gimp-image-get-active-layer image))))
(gimp-drawable-transform-scale-default
image drawable 0.0 0.0 width height 1 1 )
(gimp-image-resize image width height 0 0)
(gimp-file-save RUN-NONINTERACTIVE
image drawable filename filename)
(gimp-image-delete image))
(set! filelist (cdr filelist)))))
Saved it as autoskaler.scm in ~/.gimp-2.2/scripts and tries to run it batch
with: gimp -i -b '(autoskaler "*.JPG" 1600.0 1200.0 )' '(gimp-quit 0)'
Then it presents me with: batch command: experienced an execution error. Hmm,
tries the interactive script-fu console using (autoskaler "*.JPG" 1600.0
1200.0 ) and it then says:
ERROR: Procedural database execution failed:
(gimp_drawable_transform_scale_default 1 2 0 0 1600 1200 1)
And now I can't figure out whats wrong since I have a reference to both an
image and a layer. Most of the code I just copied from the batch section of
the docs on gimp.org.
I really like the way gimp scales images, so it would be great to have this
script work.
Best regards
Knut
