The GIMP.ORG (http://gimp.org/tutorials/Basic_Batch) tutorial seems to be up-to-date and covers just about all that you need to know. Also, have you visited GIMPtalk.com and searched for the term "batch". That should provide some good examples that do almost exactly that which you described.

If you have any specific questions, I shall be happy to try to answer them.

Quoting "B.W.H. van Beest" :

I would like to create a jpg image from a gimp xsf-file, but in batch mode. (for instance, to have it as a rule in a Makefile) I have been struggling with this for quite some time, but all attempt have failed. Browsing the web did not yield workabale references or examples. It seems that info on script-fu all is outdated?

Is there somebody around who can who me how to do this?

Hi, i assume you made a typo and meant xcf. i use a modified (trivially) version of the converter xcf2jpg by Patricio Moracho. for example:

## xcf2jpg pic.xcf pic.jpg

web page is in Spansish, but the open source code is very short and well documented.

You might want to consider Davids batch processor http://members.ozemail.com.au/~hodsond/dbp.html

Using ImageMagick might also be worth considering.

Quoting "B.W.H. van Beest" :

802] test> gimp -i -b '(file_jpeg_save RUN-NONINTERACTIVE "blurk.xcf" 2 "aap.jpg" "aap.jpg" 80.0 0.0 0)' '(gimp-quit 0)' No batch interpreter specified, using the default 'plug_in_script_fu_eval'. batch command: experienced an execution error. [803] test> What am I doing wrong?

The "image" parameter in any script-fu function is actually a number which is defined when the image is loaded into the GIMP; it is *not* a filename. It is necessary for you to create a short script which loads your file into the GIMP and *then* saves back to disk.

I have written just such a script for you which you can find at http://flashingtwelve.brickfilms.com/GIMP/Scripts/batch-xcf2jpg.scm

The script should be executed from the command line as follows:

gimp --no-interface -b '(batch-xcf2jpg "pattern.ext")' '(gimp-quit 0)'

Where the string ("pattern.ext" in the example) is a wildcard pattern of all of the files which you wish to be converted; the pattern can also be just a specific filename (for example, "someimage.xcf"). The script can be used to convert other formats (PNG, GIF, etc) by changing the extension (the output is always JPEG).

suggestion of ImageMagick was perfect. I never realised that ImageMagick supportted .xcf files.

imagemagick v6.2.7 will flatten some multilayer xcf files okay. but in my experience, not others. prior versions of IM always flattened correctly any multilayer xcf that I gave it. so i switched to xcf2jpg

This is why top posting is bad! I assume you are referring to:

That link works OK for me (and I'd want to know if it was broken). However, your original message implied that you wanted to do the batch processing from the command line. DBP does batch processing from the Gimp gui.

You can always try the Google Cache or the web archive if a link doesn't work for you:

Other programs are discouraged from supporting XCF and it isn't a fully documented standard or anything so they do well considerin but you should check your files and make sure they results are correct.
