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:
getInput(), setInput(Effect)

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

getRadius(), setRadius(double)

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.

blurType

public final ObjectProperty<BlurType> blurTypeProperty
