0.025002 BTC has been sent to ChasingCars - thanks for your help.

Arwin, I appreciate the help, but in the OP I specifically said I wanted to use the command line.

Got the money!

Thank you so much!

Cheers!

Nevermind, I had *.JPG, but all of my files are .jpg (lowercase).

Now it works.

(define (batch-resize pattern width height)
(let* ((filelist (cadr (file-glob pattern 1))))
(while (not (null? filelist))
(let* ((filename (car filelist))
(image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
(drawable (car (gimp-image-get-active-layer image))))
(gimp-image-scale-full image width height INTERPOLATION-CUBIC)
(gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
(gimp-image-delete image))
(set! filelist (cdr filelist)))))

This particular script takes a pattern for filename, desired width and height as inputs and resize all image files that are matched. This script overwrites the existing file. In order to run the script, save it with .scm extension in the ~/.gimp-/scripts/ directory.

Then goto the directory which contains images, then run the following command to resize images:

gimp -i -b '(batch-resize "./pics/*.jpg" 500 500)' -b '(gimp-quit 0)'

That runs fine, but it doesnt actually change the pictures. They are still the same size.

To the later two posters, I dont want to use imagemagik and I don't want to use the GIMP gui. I want to do this using GIMP from the command line.

If you have ImageMagik installed you can simply:

Code:

convert '*.jpg[500x]' resized%03d.jpg

Try this:

Code:

sudo apt-get install gimp-plugin-registry

Then, open up Gimp and open the Batch plugin found in Filters > Batch > Batch Process.

Select your images in the Input tab, and define the Resize operation in the surprisingly-named Resize tab.

Thanks to both of you, but I still get the same error.

and you can see I do have images in the directory:

desktop@desktop-desktop:~/pics$ ls

desktop@desktop-desktop:~/pics$

Also - post your address so I can pay.

is it not batch resize you need to use

Code:

gimp -i -b '(batch-resize "./pics/*.jpg" 500 500)' -b '(gimp-quit 0)'

Yeah, this is it.

Was about to post it but I guess you got here first, damn.

Well, at least you've worked it out, cheers!

I am running ubuntu. I have a directory with many jpgs in it, they are all the same size. I want to resize all of them to 500 x 500 pixels.

I want to use GIMP command line functions.

The files are in /pics

I am trying:

Quote

gimp -i -b '(gimp-image-scale "./pics/*.jpg" 500 500)' -b '(gimp-quit 0)'

The error I get is:

Quote

batch command experienced an execution error:
Error: ( : 1) Invalid type for argument 1 to gimp-image-scale

Surely I am doing something stupid and I am willing to pay someone 0.025BTC to help me, I've already wasted too much time on this.

Check my posting history, I have paid many rewards in the past for help like this.
