Description

Apply a gaussian blur

Help

Applies a gaussian blur to the drawable, with specified radius of affect. The standard deviation of the normal distribution used to modify pixel values is calculated based on the supplied radius. Horizontal and vertical blurring can be independently invoked by specifying only one to run. The IIR gaussian blurring works best for large radius values and for images which are not computer-generated.
