Re: --sharpening - Stength, Bandwidth?

Sharpening means enhancing edges in the picture. The "bandwidth" has to do with how distinct an edge must be to get enhanced by the program. The higher the bandwidth, the more edges are enhanced, and if you set the bandwidth very high you fill see that pixels far from an actual edge are changed. The "enhancement" is done by increasing the contrans in a region.
Actually bandwidth might not the correct name for it, but that was what I called it when I created the method.
