All Implemented Interfaces:

Paint, Transparency

public class DialConicalPaint
extends Object
implements Paint

A Paint for a Dial that allows you to specify which color(s) should appear at which angles, using the pivot point of the dial as the centre of the radius when computing the angles. Angles in between the specified angles are filled with a color derived as a linear gradient paint of the angle. Angles are specified in degrees between 0 and 360, or between -180 and 180 if you prefer.
