plug_in_gauss_rle (1995-1996)

NAME

plug_in_gauss_rle - Applies a gaussian blur to the specified drawable.

SYNOPSIS

plug_in_gauss_rle (run_mode,image,drawable,radius,horizontal,vertical)

DESCRIPTION

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 RLE gaussian blurring performs most efficiently on computer-generated images or images with large areas of constant intensity. Values for radii less than 1.0 are invalid as they would generate spurious results.
