[Gimp-developer] help required
Hi all, I am very newly introduced to GIMP. now i need to do 2D image rotation and needs to read pixel values at some specified coordinates. can anyone guide me in this aspect by pointing to me any simple example codes written using GIMP libraries ...

[Gimp-developer] [maybe OT?] Code excerpts from the GIMP
Howdy - Here's a bit of GIMP code publicity I thought folks might be interested in. I'm working on a tutorial for IBM's developerWorks site on the GLib collections - GSList, GHashTable, GTree, and all that. As part of the tutorial, I'm picking out excerpts of various collection type usages from a couple of nice open source apps - like the GIMP. Here's a list of the references to the GIMP that I've currently got in the article: http://infoether.com/~tom/gimp_snippets.html If anyone has any suggestions/corrections to the descriptions of these usages, please email me at [EMAIL PROTECTED] (or here if you think it's on-topic enough). Many thanks, Tom Copeland [EMAIL PROTECTED] ___ Gimp-developer mailing list Gimp-developer@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

I just want to make you aware that the example in gimp-2.2.4/app/base/boundary.c does not actually get used currently. If you're curious: this algorithm is a modified version of the douglas peucker algorithm for line simplification. A discussion why this code is currently unused can be found here: http://bugzilla.gnome.org/show_bug.cgi?id=50730 Feel free to ask me about this code and the vector-related stuff in your examples.

[Fwd: Re: [Gimp-developer] [maybe OT?] Code excerpts from the GIMP]
Forwarded Message From: Sven Neumann [EMAIL PROTECTED] gimp-2.2.4/app/core/gimppreviewcache.c uses a GSList as a sort of size-based queue; it holds image previews in a GSList and uses g_slist_insert_sorted to insert the smaller images first. Oddly, another function in the same file trims the cache by iterating over the same GSList and comparing each item to find the smallest one to remove. Might be a possibility for some optimization there. The function preview_cache_remove_smallest() which is used to trim the cache actually uses a different comparison than what is used to keep the list sorted. Whether this is what the author intended, I don't know. Ah, you're right, it uses the area vs an x1 x2 and y1 y2 comparison. I've corrected that comment, thanks much! http://infoether.com/~tom/gimp_snippets.html It might be of interest to your readers to also include GimpList as an implementation of the GimpContainer class. That is interesting. Backed by a GList, and sortable, and does unique names too, huh? Pretty cool.

First advice: Configure your mailer to not send HTML and to not attach vcf files. And after the first advice, to answer your question: If all you need is what you describe,m you are in agood position to use the GIMP - Python bindings. You will be at a disvantadge if you are in a non-posix OS, though, as GIMP-Python bindings do not build on this peculiar platform. Just install/compile gimp-python, check the example scripts (sphre.py). If you need to learn python, 20 or 30 minutes at www.gimp.org, pick the links to the tutorial, will do. And them, just check what functions you need from the GIMP's PDB (XTNS-PDB browser) , like the gimp_drawable_get_pixel function. It is not really hard. You can also do similar in scheme and C languages, if you prefer,or even perl.
