Functions

getBlitFunc

BlitFunc getBlitFunc()

returns a BlitFunc for use by the rasterizer

setCoords

void setCoords(float x0, float y0, float x1, float y1)

Specifiy the orientation in terms of an circle, for that we need two points, (x0,y0) is the center of the circle (x1,y1) is radius at 0 degrees

setCoords

void setCoords(float x0, float y0, float x1, float y1, float x2, float y2)

Specifiy the orientation in terms of an elipse, for that we need 3 points... (x0,y0) is the center of the elipse (x1,y1) is radius at 0 degrees (x2,y2) is radius at 90 degrees The radii dont need to be at right angles, so it can handle elipse that has been though any affine transform.

setPaint

void setPaint(Gradient grad, WindingRule wrule, RepeatMode rmode, float numRepeats)

set the gradient, winding rule and repeat mode. "numRepeats" sets how many times the gradient repeats in 360 degrees.
