Description
This filter creates lines and shapes, sometimes unusual shapes, in and around the contours of an image. These lines can be changed to "sketch" lines.This is a modified version of the reaction-diffusion method. I am calling it derivative diffusion. Original code for reaction diffusion by SpaceRay with additions by Skybase. Thanks!A quick start guide can be found at:http://duim.com/filterforge-DRVG (Username: filter Password: forge). The filter can be SLOW. It contains 4 blur & 4 high pass components to be able to make this effect. Higher values of Line Size, Line Softness or Sketch Line? mode are slower. I would consider a 4 core or more CPU as a minimum requirement for this filter.
