getX

public double getX()

Returns the X coordinate of the upper-left corner of the framing rectangle in double precision.

Specified by:

[getX](../../../java/awt/geom/RectangularShape.html#getX%28%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Returns:

the X coordinate of the upper-left corner of the framing rectangle.

Since:

1.2

getY

public double getY()

Returns the Y coordinate of the upper-left corner of the framing rectangle in double precision.

Specified by:

[getY](../../../java/awt/geom/RectangularShape.html#getY%28%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Returns:

the Y coordinate of the upper-left corner of the framing rectangle.

Since:

1.2

getWidth

public double getWidth()

Returns the width of the framing rectangle in double precision.

Specified by:

[getWidth](../../../java/awt/geom/RectangularShape.html#getWidth%28%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Returns:

the width of the framing rectangle.

Since:

1.2

getHeight

public double getHeight()

Returns the height of the framing rectangle in double precision.

Specified by:

[getHeight](../../../java/awt/geom/RectangularShape.html#getHeight%28%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Returns:

the height of the framing rectangle.

Since:

1.2

isEmpty

public boolean isEmpty()

Determines whether the RectangularShape is empty. When the RectangularShape is empty, it encloses no area.

Specified by:

[isEmpty](../../../java/awt/geom/RectangularShape.html#isEmpty%28%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Returns:

true if the RectangularShape is empty; false otherwise.

Since:

1.2

setFrame

public void setFrame(float x, float y, float w, float h)

Sets the location and size of the framing rectangle of thisShape to the specified rectangular values.

Parameters:

x - the X coordinate of the upper-left corner of the specified rectangular shape

y - the Y coordinate of the upper-left corner of the specified rectangular shape

w - the width of the specified rectangular shape

h - the height of the specified rectangular shape

Since:

1.2

setFrame

public void setFrame(double x, double y, double w, double h)

Sets the location and size of the framing rectangle of thisShape to the specified rectangular values.

Specified by:

[setFrame](../../../java/awt/geom/RectangularShape.html#setFrame%28double, double, double, double%29) in class [RectangularShape](../../../java/awt/geom/RectangularShape.html "class in java.awt.geom")

Parameters:

x - the X coordinate of the upper-left corner of the specified rectangular shape

y - the Y coordinate of the upper-left corner of the specified rectangular shape

w - the width of the specified rectangular shape

h - the height of the specified rectangular shape

Since:

1.2

RectangularShape.getFrame()

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](../../../java/awt/Shape.html#getBounds2D%28%29) in interface [Shape](../../../java/awt/Shape.html "interface in java.awt")

Returns:

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

Since:

1.2
