Hi, Since I've touched app/xcf.[ch] too: I hereby give my permission for anyone to use the portions of xcf.c that I have written under the terms of the LGPL. Please note that we consider to add a thumbnail of the image composition to the XCF file format. This might even happen before 1.2... Salut, Sven

I don't think this puts those files into the public domain A copyright notice has not much to do with the license in most parts of the world. According to the Berne convention (something the US has signed but not ratified yet for example) anything you find which doesn't have an explicit license mustn't be used, looked at, copied etc..., thus giving authors a maximum of assurance. I hereby give my permission for anyone to use the portions of xcf.c that I have written under the terms of the LGPL. The problem, of course, will be SP, which are very difficult to contact. It took quite a long time until I had the license changed from GPL to LGPL for a single file in libgimp, so whoever weants the license changed should act soon ;) -- -==- | ==-- _ | ---==---(_)__ __ __ Marc Lehmann +-- --==---/ / _ \/ // /\ \/ / [EMAIL PROTECTED] |e| -=/_/_//_/\_,_/ /_/\_\ XX11-RIPE --+ The choice of a GNU generation | |
XCF loader for gdk-pixbuf
Hello, dudes, Jens Finke [EMAIL PROTECTED] has sent me an amazing patch to add support for XCF file loading to gdk-pixbuf. I would really like to have this sort of functionality so that simple programs like EOG can view GIMP files. However, there is the issue of licensing. Gdk-pixbuf is released under the LGPL, and the XCF loader uses big chunks of GPLed code from the GIMP. I am not sure what is the best way to proceed. [For the GIMP developers who may not be aware of how gdk-pixbuf works, it is a little library that lets you load images and perform some simple operations on them. The image loaders are loaded on demand as shared libraries, so we have dynamic objects for GIF, JPEG, PNG, TIFF, etc.] I would appreciate your suggestions. Thanks, Federico

Well, there are not many options. a) You find all the authors of that GPL code and get the license changed (avoiding this mess is the advantage of copyright assignment...) b) You don't include the code in gdk-pixbuf c) You do a clean-room reimplementation of the code Havoc

BTW, I'd suggest that we put the xcf code into a library for Gimp 2.0. Gdk-Pixbuf and whatever-image-viewer will then use the same code as The GIMP for loading XCFs. ciao, --Mitch

It's surely quite hard to find _all_ contributors to the code. And b) isn't a good solution if you imagine what cool applications could be done with a xcf-loader module (e.g. nice image cataloging tools). Also there are a lot of modifications to the original gimp code in the xcf-loader yet. So a clean rewrite is probably the best solution for everyone. Regards, Jens

Actually, I think that the version that was initially put into CVS was pure SP, so the CVS log should adequately document all contributors since then. Kelly

Havoc Pennington [EMAIL PROTECTED] writes: Martin Baulig [EMAIL PROTECTED] writes: Well, then I think you misunderstood me. What I suggested was added XCF as a nice add-on to gdk-pixbuf for the situation where gdk-pixbuf is used under the GPL. Of cause, this means that you can't use XCF loading in a proprietary app where you use gdk-pixbuf under the LGPL. Maybe. It's a big can of worms though - can Red Hat and SuSE ship the XCF add-on, for example? Probably not. Hmm, yes. -- Martin Baulig [EMAIL PROTECTED] (private) [EMAIL PROTECTED] (work)
