Hello all,
My name is Luis de Bethencourt Guimerá (d33p in the irc channel). A few days ago I decided I'm really interested in being part of the gimp project. I've been doing some research and decided to start with a a bug with the gnome-love tag I finded in bugzilla, it's the bug #312800 ( http://bugzilla.gnome.org/show_bug.cgi?id=312800). So once getting my hands into the sel_gaus plug-in, I saw I have a long path ahead. First I will have to learn some gtk, just to handle the interface coding before getting to the fun image processing part and start understanding the internals of gimp. I write this to introduce myself and comment my will of fixing the bug. Obviously any advice and help will be welcomed. cheers,
Luis

pd: sorry for my horrible english, english is my second language after spanish

Thanks for the replies, really charming =). I got myself to gtk developer manuals, the one written by havoc pannington ( http://developer.gnome.org/doc/GGAD/) and the one in the gtk webpage. My interest in learning gtk is to apply it to gimp, understand how the interface works and connects to the internal process and be able to change it if necessary (like adding a new option to a plug-in for example). At the same time I'm going to be reading a classic book I found in my college's library, "computer graphics: principles and practices" by Foley and Van Dam. Old stuff but basics are always applicable. I know I can find figure out the "how things work" looking into the gimp code, but want to get the basics in my head meanwhile I start. If anybody knows a better book out there for this purpose let me know please. I saw one written by Sun but didn't seam so complete as the other. cheers,
Luis

pd: not d33p anymore in the irc channel but luis (or similar since luis seams to be taken)

Hah! Well, same story for me, actually. I've been just going through the code over and over again, seeing something I didn't notice before, taking an hour of research here and there. It's a slow process, but when you get how some stuff works, it really wows you. The code is surprisingly easy to read once you get the system down of how it's made. One thing I decided to do was look at some of the way earlier code for gimp when I didn't get how something ties in with the rest. I still haven't really done much with the older gimp code yet, so I don't know how much it really helps with understanding, but you could try that as well. Then again, if all you want to learn is GTK, I can't help you there as I've mostly just been studying the graphics tools in gimp right now. I'm starting to get in to that, though. Tell me if you find any really good stuff for helping to understand and debug gimp more. I for one have a hard time asking the right questions on the irc list because I'm starting out so far behind.

Stick to it... it doesn't look impossible for me, so I'm sure you'll do fine.

Oh, and your english is fine. ;-)

I don't have much advice for you up front, but I do have a welcome. Thanks for committing to chip in and make this corner of the world a better place!

Hah! If you think you've got problems with English, try my Spanish one day. (-:

Thanks for your reply Sven. I just made a reservation to pick up tomorrow in the library the gonzalez and woods book "Digital Image Processing", looks really good. I will start slowly and fixing little bugs, probably ones with the gnome-love tag, but my interest is image processing. I'll just need some patience =)
cheers,
Luis

The book you are referring to deals with the GTK+ 1.2 API which is not 100% compatible to GTK+ 2.x. I would not recommend it any longer. The online GTK+ tutorial is reasonably well maintained though and should get you further. But the best way to learn GTK+ is to read code.

At the same time I'm going to be reading a classic book I found in my college's library, "computer graphics: principles and practices" by Foley and Van Dam. Old stuff but basics are always applicable.

"Foley, van Dam, ..." is a very good book that I can recommend. Large parts of it don't have much relevance for GIMP though.

It really depends on what you are interested in. There are some good books on image manipulation algorithms such as the one from Gonzalez and Woods. But you can spend years hacking on GIMP w/o having any clue on image manipulation algorithms.
