The only documentation for the xcf format *is* the source code in xcf.c and other files. > It's a pity.

He told me that he wouldn't be making the viewer able to parse xcf files completely, anyway, as that would be too complex. Only the bottom layer would probably be shown. (This is how IrfanView works for psd (Photoshop) files, too, I think.) And as the only reasonable reason to use xcf format in the first place is when you are working on some multi-layer or otherwise complex image in the GIMP and want to save it between editing sessions, wouldn't it be counter-productive if IrfanView would show only the bottom layer? Xcf is not intended to be an image distribution format, or an image interchange format between applications. I don's see why anybody would distribute xcf images except if they are 100% sure that the recipient(s) are going to work on them with the (same version of) GIMP. --tml
