In order to get Python plug-ins for GIMP on Win32, you need: 1. Python You can use ActviePython, probably the most common Python distribution for Win32: http://www.activestate.com/Products/ActivePython/ 2. PyGTK The python binding to GTK+. Available as installers from http://www.pcpm.ucl.ac.be/~gustin/win32_ports/ 3. PyGIMP itself Built using the distutils tools, which are part of Python (and not the current autotools build). 4. A fix for bug 98737 http://bugzilla.gnome.org/show_bug.cgi?id=98737 Basically, glib can't run scripts on win32 right now. I did step 3 myself (the resulting setup.py is rather poor, though) and use a modification to gimp's plug-in handling code to get around step 4. PyGTK can be built without problems if you have a build environment that allows ou to build GIMP, so it can probably serve as an example on how to create a proper PyGIMP distutils build.

Re: [Gimp-user] Scheme question
I have been trying to write some scripts to automate tasks but find that I have some trouble using scheme. Although I am experienced in other languages I find scheme quite difficult to master as I can't seem to find any language references. There are lots of tutorials and samples showing how to create scripts but nothing that I could find that actually describes the language, functions available, etc. The big problem w/ Gimp's scheme is that they use a version that is not really respected by anyone and that's horribly out-of-date. I think they did that in the spirit of keeping things simple, but it's horribly backfired. Scheme is one of the most ingenious languages around. I'll be describing some of its more interesting features this coming year in several IBM DeveloperWorks articles. Unfortunately, many of these features aren't available on GIMP's scheme. For learning scheme as a language, some good books are: Teach Yourself Scheme in Fixnum Days (available on the web somewhere) How to Design Programs Simply Scheme a more advanced introduction, which every serious programmer should read sometime in their life, is Structure and Interpretation of Computer Programs In addition, the scheme standard is only 50 pages, and is a pretty easy read.

I do notknow if that is an up to date implementation, however. All I know is that it currently doesn't support multi-byte character encodings - i.e. UTF-8, just like GIMP's native script-fu.

[Gimp-user] Scheme question

There are lots of tutorials and samples showing how to create scripts but nothing that I could find that actually describes the language, functions available, etc. At the moment I am trying to work out how to do integer division. I want to draw guides mapping the rule of thirds and want to ensure that I get an integer result when I divide the image height and width by 3. How would I do this?

But I will insist on this subject. I'd like to see more people using gimp python. Getting the integer part of a image width and height would be as complex as: width_3 = image.width / 3 heigth_3 = image.height / 3 where image is an image object passed by ptyhon-fu to every python script that needs an image as a parameter. As both numbers on above opertaions are int, so is the result. Would one need the integer number of a division by 2.5: width_25 = int (image.width / 2.5) Regards, JS -- ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
