This plugin will take the active path and smooth it, using a Bezier
interpolation algorithm. If you've ever wanted to define a bunch of
points, and then have the GIMP draw a smooth path through them, this
plugin is for you. There is the option to smooth corners between a
range of angles.
This plugin creates a new entry in the Paths dialog right-click menu.
For details of the algorithm used in this plugin, see here:
Be sure to read the readme.txt file for installation and user help.
