Blur algorithm

[AlannY]

Hi there, my name is Alan.

I know that this mailing lists is for GIMP developers, but I need some
help from graphics expert.

I'm writing a small programs which blurs some image. I need working Blur
Algorithm. Can someone help me with it? Maybe there are good tutorial of
implementation of blur in web? Or may be you poke me in some lines in
GIMP sources where the CORE of Blur algorithm. I'm second day searching
in GIMP sources, but can't find something useful.

If you can't understand my english - just skip this letter ;-)

As usual, gamedev.net is your friend

Good blurring algorithms generally use convolution with a base kernel;  
changing the base kernel
changes the nature of the blurring.

There is a good general-purpose convolution algorithm in the Perl Data  
Language codebase at
http://pdl.perl.org.  Look for the "imagend.pd" file.  Don't let the  
".pd" metalanguage
suffix fool you -- the stuff you want to look at is written in "C".  
It's Artistic Licensed;
If I remember right, AL and GPL were compatible, so you may be able to  
simply cut, paste, and
glue.
