Constructor Summary

Constructors

Constructor and Description
RMSize() Creates a size initialized to 0,0.
RMSize(java.awt.Dimension d) Creates a size from a java2D dimension
RMSize(double w, double h) Creates a size initialized to the given width and height.
RMSize(RMSize aSize) Creates a size initialized to the given size.

Method Summary

Modifier and Type	Method and Description
RMSize	abs() Normalizes the receiver to positive values.
boolean	equals(float w, float h) Returns whether size is equal to given width and height.
boolean	equals(java.lang.Object anObj) Standard equals implementation.
float	magnitude() Returns the square root of the sum of the squares of the width and height.
void	negate() Simply sets the width and height to their negatives.
RMSize	normalize() Normalizes the receiver by scaling its width and height such that its magnitude will be 1.
RMSize	transform(RMTransform aTransform) Transforms size by given transform (return this for convenience).
