Constructor Detail

Ellipse

public Ellipse(double X1,
               double Y1,
               double r1,
               double r2,
               java.awt.Stroke strock,
               java.awt.Color color)

Create an ellipse with given semimajor and semiminor axes, centered on (x, y). Major axis: The longest diameter of an ellipse. Minor axis: The shortest diameter of an ellipse. Semimajor is major/2.

Parameters:

X1 - X center position

Y1 - Y center position

r1 - radius in X, or semimajor axis of the ellipse (major divided by 2).

r2 - radius in Y, or the semiminor axis of the ellipse (minor divided by 2).

strock - Stroke

color - Color

               double Y1,
               double r1,
               double r2)

Create an ellipse using the default stroke and the color

Parameters:

X1 - X center

Y1 - Y center

r1 - radius in X, or semimajor axis of the ellipse (major divided by 2).

r2 - radius in Y, or the semiminor axis of the ellipse (minor divided by 2).
