                          float y2,
                          Color color2)

Constructor for a simple acyclid AgileGradientPaint object.

Parameters:

x1 - y1 coordinates of the first specified Point in user space

color1 - Color at the first specified Point

x2 - y2 coordinates of the second specified Point in user space

color2 - Color at the second specified Point

Throws:

NullPointerException - if either one of colors is null

AgileGradientPaint

public AgileGradientPaint(Point2D pt1,
                          Color color1,

Constructs a simple acyclic AgileGradientPaint object.

Parameters:

pt1 - the first specified Point in user space

color1 - Color at the first specified Point

pt2 - the second specified Point in user space

color2 - Color at the second specified Point

Throws:

NullPointerException - if either one of colors or points is null
