Method Detail

sqDistance

public static int sqDistance(java.awt.Rectangle r,
                             java.awt.Point p)

Calculate the minimum square distance between the given rectangle and the given point.

fitRectangle

public static void fitRectangle(java.awt.Rectangle frame,
                                java.awt.Dimension d,
                                boolean maintainAspect)

Make a dimension fit the given framing rectangle by reducing its size. If the given dimensions do not fit, they are scaled while maintaining aspect ratio.

Parameters:

frame - The containing rectangle

d - The dimension to shrink.

maintainAspect - Whether the aspect ration of d should be maintained.

placeRectangle

public static void placeRectangle(java.awt.Rectangle r,
                                  java.awt.Dimension d,
                                  java.awt.Point p,
                                  java.awt.Rectangle out)

Place a rectangle with the given size into the given rectangle with its center as close as possible to the given point. It may be reasonable to call fitRectangle first on the dimension. This function assumes that the dimension fits the rectangle.
