equal

public static boolean equal(java.awt.Polygon p1,
                            java.awt.Polygon p2)

Deprecated.

Tests two polygons for equality. If both are null this method returns true.

Parameters:

p1 - polygon 1 (null permitted).

p2 - polygon 2 (null permitted).

Returns:

A boolean.

translateShape

public static java.awt.Shape translateShape(java.awt.Shape shape,

                                            double transY)

Deprecated.

Returns a translated shape.

Parameters:

shape - the shape (null not permitted).

transX - the x translation.

transY - the y translation.

Returns:

The translated shape.

rotateShape

public static java.awt.Shape rotateShape(java.awt.Shape base,
                                         double angle,
                                         float x,
                                         float y)

Deprecated.

Rotates a shape about the specified coordinates.

Parameters:

base - the shape (null permitted, returns null).

angle - the angle (in radians).

x - the x coordinate for the rotation point (in Java2D space).

y - the y coordinate for the rotation point (in Java2D space).

Returns:

the rotated shape.

drawRotatedShape

public static void drawRotatedShape(java.awt.Graphics2D g2,
                                    java.awt.Shape shape,
                                    double angle,
                                    float x,
                                    float y)

Deprecated.

Draws a shape with the specified rotation about (x, y).

Parameters:

g2 - the graphics device (null not permitted).

shape - the shape (null not permitted).

angle - the angle (in radians).

x - the x coordinate for the rotation point.

y - the y coordinate for the rotation point.

createDiagonalCross

public static java.awt.Shape createDiagonalCross(float l,
