Detailed Description

Gaussian Blur filter.

Library: ilvbmpflt

This bitmap filter lets you perform a Gaussian Blur on an image.

The Gaussian Blur kernel is an approximation of the normalized convolution: H(x) = exp(-x^x / (2 * s^s)) / sqrt(2 * pi * s^s) where s is the user-specified standard deviation. This filter is implemented as two successive horizontal and vertical kernels. Different deviations can be given for x and y directions.
