Re: [Gimp-developer] Best way for limit distance
Thanks for the suggestion. Using Joao [EMAIL PROTECTED] lead I use for now python-fu with the numarray extension. As far as I know such speedups are something scrip-fu is not capable off, and I truly hope one day script-fu will be phased out and python-fu (or any other sane scripting language) will take it's place.Others might disagree, but I don't consider perl sane :) BTW, all this was part of a small evaluation of CCD noise removal method. If you are interested, the details are in http://pages.quicksilver.net.nz/pepe/d70/Nikon_D70_on_Linux.html#ISONoise The results are quite dismaying. I appreciate any insight on the subject. However please note I am not looking for a solution for the specific image I used, but a generic one. -Joseph Øyvind Kolås wrote: On Tue, 30 Nov 2004 13:25:16 +1300, Joseph Heled [EMAIL PROTECTED] wrote: (I think this has been discussed on the list before, but not sure where/when.) What is the best way to achieve the following functionality - Given two layers L1 and L2, I want L2 limited by it's distance from L1 Result - L1 - MIN( MAX(L1 - L2), -20), 20) Options: A. Write a plugin B. Write it as a script-fu (not sure if script-fu can iterate on pixels, and what is the speed implication). And I hate scheme. C. Write it in python fu if I can compile it, but even though it is probably not as universally available as scrip-fu. Can I iterate over an image in python-fu? D. I know I can do it with 5 layers and overlay modes. write this as a script-fu. Not elegant and requires loads of memory for large images. E. extend gluas to be able to pick an auxiliary drawable for additional pixel sources, (essentially resurrecting some code I initially had in a different version of gluas, and write the expression in gluas).

Re: [Gimp-developer] Best way for limit distance
I am using gimp-2.2-pre2. I certainly get totally different results than you for the same setting. I would appreciate some advice on how to find out how can that be, -Joseph Øyvind Kolås wrote: On Fri, 03 Dec 2004 10:12:37 +1300, Joseph Heled [EMAIL PROTECTED] wrote: BTW, all this was part of a small evaluation of CCD noise removal method.

I replaced the original on my page with a png file, which you can grab if you wish and see the problem for real. While your settings are definitely better, personally I find the result not good enough. And as I mentioned, the speed of the plugin is a big deterrent as well. -Joseph ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
