standard deviation for Gaussian Blur
Hello,

for a project Im working on I need to be able to calculate the Standard Deviation from the Gaussian Blur function used in Gimp. How do I calculate (or how does GIMP calculate the standard dev) when I blur an image with say.. 10 pixels x 10 pixels blur radius.

Thanks!

RE: standard deviation for Gaussian Blur
Thanks! The standard Dev seems okay when I calculate it using this formula and the pixels I specified. I was wondering if there might be another formula between pixels and vert though, because GIMP also allows you to specify the radius in cm/mm or inch. Ive found vert = fabs (vert) + 1.0; on another website, but I don't really know what that means.. I ll also ask on the developer mailing list.
