plug_in_laplace - Edge Detection with Laplace Operation
SYNOPSIS
plug_in_laplace (run_mode,image,drawable)
DESCRIPTION
This plugin creates one-pixel wide edges from the image, with the value proportional to the gradient. It uses the Laplace operator (a 3x3 kernel with -8 in the middle). The image has to be laplacered to get useful results, a gauss_iir with 1.5 - 5.0 depending on the noise in the image is best.
