Constructor Detail

JWRectangle

public JWRectangle(float width,
                   float height)

Creates a rectangle with given dimensions and 0 origin.

Parameters:

width - Width of rectangle.

height - Height of rectangle.

JWRectangle

public JWRectangle(Dimension dimension)

Creates a rectangle from a given AWT Dimension object.

Parameters:

dimension - AWR Dimension object.

JWRectangle

public JWRectangle(Rectangle rect)

Creates a JWRectangle from a given AWT Rectangle object. Note that as well as converting integer coordinates to floats, the origin is flipped from top left to bottom left.

Parameters:

rect - AWT Rectangle object.

Returns:

Dimension of rectangle.

getRectangle

public Rectangle getRectangle()

Converts the rectangle into an AWT Rectangle object. Note that the origin, width and height are converted into integers and the the origin is flipped from the bottom left to top left.

Returns:

AWT Rectangle representation.

toString

public String toString()

Returns a string representation of this object.

Overrides:

toString in class Object

Returns:

String String representation of this object.
