public class RadialPattern extends Pattern
After calling this and before using the RadialPattern you need to call
addColorStopRGBA() a few times to set up the gradient. For example, to
create an circular alpha blend:
pattern = new RadialPattern(75, 75, 25, 75, 75, 120); pattern.addColorStopRGBA(0.0, 0.0, 0.0, 0.0, 0.0); pattern.addColorStopRGBA(1.0, 0.0, 0.0, 0.0, 1.0);and then you can get on with using the Pattern in drawing operations:
cr.mask(pattern);

Create a Pattern with a radial gradient between two circles.

double cy0,
double radius0,
double cx1,
double cy1,
double radius1)
cx0,cy0 with a radius
of radius0, and the second circle is centered at
cx1,cy1 with a radius of radius1
.
Quite typically, you will want a strict radial pattern from a common
centre, in which case have cx1,cy1 equal to
cx0,cy0.
