Hi, I am trying to convert the gauss_iir plugin to be able to handle floating point images. I can see, in some place where 8 bits values are hard-coded, but not everywhere. Since I am not to familiar with the gaussian blur filter kernel, I am wondering if someone could point me to more information, url, article on the gaussian blur. Thank you, -- M. Talbot ing.
