The upper-left x coordinate of the bounding-box

y

public float y
The upper-left y coordinate of the bounding-box

Constructor Details

Float

public Float()
Creates a new Ellipse2D with an upper-left coordinate of (0,0) and a zero size.

Float

public Float(float x,
             float y,
             float w,
             float h)
Creates a new Ellipse2D within a given rectangle using floating-point precision.

Parameters:
x - - x coordinate of the upper-left of the bounding rectangle
y - - y coordinate of the upper-left of the bounding rectangle
w - - width of the ellipse
h - - height of the ellipse

Method Details

getBounds2D

public Rectangle2D getBounds2D()
Returns the bounding-box of the ellipse.
Specified by:
getBounds2D in interface Shape
Returns:
The bounding box.

getHeight

public double getHeight()
Returns the height of the ellipse.
Overrides:
getHeight in interface RectangularShape
Returns:
The height of the ellipse.

getWidth

public double getWidth()
Returns the width of the ellipse.
Overrides:
getWidth in interface RectangularShape
Returns:
The width of the ellipse.

getX

public double getX()
Returns x coordinate of the upper-left corner of the ellipse's bounding-box.
Overrides:
getX in interface RectangularShape
Returns:
The x coordinate.

getY

public double getY()
Returns y coordinate of the upper-left corner of the ellipse's bounding-box.
Overrides:
getY in interface RectangularShape

The y coordinate.

isEmpty

public boolean isEmpty()
Returns true if the ellipse encloses no area, and false otherwise.
Overrides:
isEmpty in interface RectangularShape
Returns:
A boolean.

setFrame

public void setFrame(double x,
                     double y,
                     double w,
                     double h)
Sets the geometry of the ellipse's bounding box. Note: This leads to a loss of precision.

Overrides:
