Converting XCF and other files using command line with GIMP?

Question

If I have an XCF file (or any other supported by Gimp) how can I convert it to, for example, PNG for display or further processing?

Answer 1

Very few, if any, programs other than GIMP read XCF files. This is by design from the GIMP developers, the format is not really documented or supported as a general-purpose file format.

That being said, look into using GIMP itself, using command line arguments (especially the --batch option).

EDIT: It looks as if ImageMagick does support XCF, so that is probably an easier route if the support seem so be good enough. I haven't tested it, and the documentation doesn't say much. I would be a bit wary.
