Class Shadow

java.lang.Object

javafx.scene.effect.Effect

javafx.scene.effect.Shadow

public class Shadow extends Effect

An effect which creates a monochrome duplicate of an input with blurry edges. This effect is primarily used along with its default black color for purposes of combining it with the original to create a shadow. It can also be used with a light color and combined with an original to create a glow effect. The DropShadow effect is a utility effect which automatically combines this Shadow effect with an original graphic for ease of adding a shadow to an existing scene graph Node with a single effect.

Since:: JavaFX 2.0

Property Details

input

public final ObjectProperty<Effect> inputProperty

The input for this Effect. If set to null, or left unspecified, a graphical image of the Node to which the Effect is attached will be used as the input.

Default value:

null

See Also:

radius

public final DoubleProperty radiusProperty

The radius of the shadow blur kernel. This attribute controls the distance that the shadow is spread to each side of the source pixels. Setting the radius is equivalent to setting both the width and height attributes to a value of (2 * radius + 1).

       Min:   0.0
       Max: 127.0
   Default:  10.0
  Identity:   0.0

Default value:

10.0

See Also:

width

public final DoubleProperty widthProperty

The horizontal size of the shadow blur kernel. This attribute controls the horizontal size of the total area over which the shadow of a single pixel is distributed by the blur algorithm. Values less than 1.0 are not distributed beyond the original pixel and so have no blurring effect on the shadow.

       Min:   0.0
       Max: 255.0
   Default:  21.0
  Identity:  <1.0

Default value:

21.0

See Also:

height

public final DoubleProperty heightProperty

The vertical size of the shadow blur kernel. This attribute controls the vertical size of the total area over which the shadow of a single pixel is distributed by the blur algorithm. Values less than 1.0 are not distributed beyond the original pixel and so have no blurring effect on the shadow.

       Min:   0.0
       Max: 255.0
   Default:  21.0
  Identity:  <1.0

Default value:

21.0

See Also:

blurType

public final ObjectProperty<BlurType> blurTypeProperty

The algorithm used to blur the shadow.

       Min: n/a
       Max: n/a
   Default: BlurType.THREE_PASS_BOX
  Identity: n/a

Default value:

THREE_PASS_BOX

See Also:

color

public final ObjectProperty<Color> colorProperty

The shadow Color.

       Min: n/a
       Max: n/a
   Default: Color.BLACK
  Identity: n/a

Default value:

BLACK
