batch script help

hello list, just added my self so i hope this is an active list.

im am attempting to batch compress OSM tile images. they are of png format, otherwise i would have used cjpeg. anyhow the script need only open the images in a folder and save them out with a different compression level [9]

after reading the [1] batch mode page i have assembled this format: (define (png-compress filename
compression) (let* ((filelist (cadr (file-glob pattern 1)))) (while (not (null? filelist))
(let* ((filename (car filelist)) (image (car (gimp-file-load RUN-NONINTERACTIVE filename filename))) (gimp-file-png-save RUN-NONINTERACTIVE image drawable filename filename))
(gimp-image-delete image)) (set! filelist (cdr filelist)))))

and run: $ gimp -i -b '(png-compress "*.png" 9)' -b '(gimp-quit 0)'

but i get: batch command: experienced an execution error.

got to say i really dont understand scripting all that much, i just really need to compress these files. thanks to anyone who can help me out here

Jeremy,

It seems to me that using Gimp for this task is perhaps not the best use of Gimp or of your time. I do not know the specific answer to your question about the problem you are encountering, but perhaps a program such as ImageMagick

http://www.imagemagick.org/script/index.php

would be more suitable. ImageMagick is specifically designed to do the kind of batch tasks that I believe I understand you wish to accomplish. We use it to process tens of thousands of images (making multiple sizes of JPEGs from TIFFs), but I don't have any specific experience with the task you are attempting.

You need to define 'drawable'. Basically, you omitted a line from the script in the tutorial.

Also, the function to save a PNG file is 'file-png-save', or 'file-png-save2' (not 'gimp-file-png-save'), and has several additional parameters that need to be specified if you are to change the compression. Use the PDB Browser under the Help Menu for more information on these parameters.

Try substituting the following for the 'gimp-file-save-png' line in your script:

(file-png-save RUN-NONINTERACTIVE image
drawable
filename
filename
FALSE ; interlace (mostly for Web usage) 9 ; compression (0-9) FALSE ; bkgd (mostly for Web usage) FALSE ; gama (may be desirable for Macs targets) FALSE ; offs (useful for page layout targets) FALSE ; phys (useful for printing targets) FALSE) ; time

and run:
$ gimp -i -b '(png-compress "*.png" 9)' -b '(gimp-quit 0)'

Hopefully you are not using Windows when you run this.

yes the drawable part was omitted because i thought it had to do with the tutorial applying the unshapen mask. in my mind i thought this was nessisary to edit the image. and that was not what i am doing.

file-... and gimp-file-... i for some reason thought it needed a gimp command prior to the actual command. misunderstanding again

no windows box, debian.

ill attempt the script again in about 2 hours when i get home. thanks

also, imagemagick i can get to work, but not much a reduction. png crush squises the files a bit better but i dont know how to command line script a folder for compression.

anything on the gimp front?

Google "gimp batch process". Five of the first six hits point to David's Batch Processor plugin.

oh thank god. this looks much like photoshops actions. if it works the same way this is a fantastic bit of information for me.

thank you

You never assign the drawable variable. Try to use (drawable (car (gimp-image-get-active-drawable image)))

Not sure if that's the only problem though.

thank you sven and tetsuya, but i have gone with David's Batch Processor and it is working well.

maybe ill try scripting later.
