Using Python Scripting it would be a matter of a few lines. The only
drawback is that you'd have to change the script code for each
processing job you need to do in the batch.
I will post here the Python script needed to rotate each image in a
dir by 270 degrees and saving the result with an "R" appended to the
filename.
I apologize for the portuguese names inside the code - I had used
this script as an example ina local forum.
You have to replace the line "pdb.gimp_image_rotate (...)" for the
actions you need applied to the image (check what is available in the
GIMP Procedure Browser in the Xtns menu). Offcourse, you also need
gimp-python installed (it is tehre if you have a "python-fu" menu
entry. Else, it is usually available from Linux distros as a
separate package, or you have to give ./configure an
"--enable-python" option if you compile your own GIMP.

Hi, you can use convert from ImageMagick. cd /dir/with_images/ for image in *; do convert -scale 100x100 $image $image; done check the man page for more info :) nuno -- "Non-free programs are dangerous to you and to your community.

[Gimp-user] Multiple file scaling
Hello list, Is it possible to rescale multiple images (ie: hundreds) without having to open each one individually in the Gimp? I guess this would be a sort of batch processing. Background: I have a perl script which I run to shrink images before uploading to the web. This typically shrinks the size (and thus upload times) of my huge 8MPixel JPEG files from 3-4MB to a few hundred KB. This works great, and I use this script all the time. I just thought it would be great if the Gimp could do something similar, as I imagine this "shrink many images before upload" is a process that many people need to do.
