I have made a Script-Fu to batch-resize images because I couldn't find one that only resizes images (only thumbnail gallerys etc.)

Just download and put to your scripts directory:

http://www.gimpusers...-resize-2.2.scm (for GIMP 2.2)
http://www.gimpusers...-resize-2.4.scm (for GIMP 2.4)

The script is German but it only has three parameters:
1) path to images, e.g. "/home/richard/tmp/*.jpg"
2) new width
3) new height

You can start the script from Xtns/Script-Fu/Verschiedenes/Mehrere Bilder verkleinern...

More images and detailled infos (text in German) are available at:
http://www.gimpusers...tch-resize.html

cant you just scale the image?

I want to scale many images, e.g. the last holiday photos. This is why i need BATCH resize

4 parameters i hope: i would like choose a folder for the resized images...or it will overwrite the originals?

[devvv]

it is intended to overwrite the original files.

you can make a copy first and then resize the duplicates.

I tried to use this with no luck and had to deal with it for the holiday's and a silly little electronic photo frame.

The 2.4 script doesn't work out of the box so I am submitting the updaed version for 2.4.

Thank you :) Nice scripts :)
I made my own modification - using single aspect ratio instead of width & height. Some things in code are most possible redundant (e.g. recalculating ratio) so somebody probably can correct this. Anyway :) Hope it's okay to put code in here - no time for safe uploading.

Put all this inside scripts directory (on my computer it's c:\program files\GIMP-2.0\share\gimp\2.0\scripts) in a text file called e.g. batch-scale-ratio.scm) and reload the scripts in GIMP menu->Xtns->Script-fu->Refresh scripts
so then you can see it under GIMP menu->Xtns->Misc

cheers!

This is exactly what I have been looking for. Thank you for posting a scaling version!

This is awesome - You rock !!

[Tonio]

Ok, so I tried to save that as what you said, into where you said etc. I have looked around, but I am really stupid by the looks of it.

All I wanted was a easy way to convert files from one size to another, pref. in a new folder.. with gimp 2.6... If anyone could help, please do...

[jasshrie]

i was searching for the same thing for Gimp 2.6 and found this:

works perfectly for me!

Good luck!
