setRoundRect

public void setRoundRect(double x,
                         double y,
                         double w,

                         double arcw,
                         double arch)

Sets the location, size, and corner radii of this RoundRectangle2D to the specified double values.

Specified by:

setRoundRect in class RoundRectangle2D

Parameters:

x - the X coordinate to which to set the location of this RoundRectangle2D

y - the Y coordinate to which to set the location of this RoundRectangle2D

w - the width to which to set this RoundRectangle2D

h - the height to which to set this RoundRectangle2D

arcw - the width to which to set the arc of this RoundRectangle2D

arch - the height to which to set the arc of this RoundRectangle2D

Since:

1.2

setRoundRect

public void setRoundRect(RoundRectangle2D rr)

Sets this RoundRectangle2D to be the same as the specified RoundRectangle2D.

Overrides:

setRoundRect in class RoundRectangle2D

Parameters:

rr - the specified RoundRectangle2D

Since:

1.2

getBounds2D

public Rectangle2D getBounds2D()

Returns a high precision and more accurate bounding box of the Shape than the getBounds method. Note that there is no guarantee that the returned Rectangle2D is the smallest bounding box that encloses the Shape, only that the Shape lies entirely within the indicated Rectangle2D. The bounding box returned by this method is usually tighter than that returned by the getBounds method and never fails due to overflow problems since the return value can be an instance of the Rectangle2D that uses double precision values to store the dimensions.

Specified by:

getBounds2D in interface Shape

Returns:

an instance of Rectangle2D that is a high-precision bounding box of the Shape.

Since:

1.2
