public class Curves
- extends CamanFilter
Curves implementation loosely based off of Photoshop's similarly named
feature. Curves in CamanJ use Bezier curves to convert an input color X into
an output color Y based on the Bezier curve.
First param is the channels you wish to apply the curve to. This is simply a
string with r, g, and or b in it. The rest of the params are the start,
control 1, control 2, and end points in x/y pairs.
Params: (String, int x 8)

is executed. This helps with speed so
that arguments don't have to be recomputed for every pixel.
