I have heard, the there is a fast way to compute a blur, over any 2D bitmap with alpha mask, with an algorythm using a method from gauss (in german its called the "Gausche-Normalverteilung". Dont know the english word for that.). Can anybody help me ?
Any other good and fast way to blur or unsharpen a 2D bitmap with alpha channel would be welcome.
Sorry for the bad english :-)
