BoxBlur (JavaFX 8)

java.lang.Object
- javafx.scene.effect.Effect
- - javafx.scene.effect.BoxBlur

public class BoxBlur
extends Effect

A blur effect using a simple box filter kernel, with separately configurable sizes in both dimensions, and an iteration parameter that controls the quality of the resulting blur.

Example:


 BoxBlur boxBlur = new BoxBlur();
 boxBlur.setWidth(10);
 boxBlur.setHeight(3);
 boxBlur.setIterations(3);

 Text text = new Text();
 text.setText("Blurry Text!");
 text.setFill(Color.web("0x3b596d"));
 text.setFont(Font.font(null, FontWeight.BOLD, 50));
 text.setX(10);
 text.setY(50);
 text.setEffect(boxBlur);

The code above produces the following:

  - 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)
  - width
```
public final DoubleProperty widthProperty
```
    The horizontal dimension of the blur effect. The color information for a given pixel will be spread across a Box of the indicated width centered over the pixel. Values less than or equal to 1 will not spread the color data beyond the pixel where it originated from and so will have no effect.
```
       Min:   0.0
       Max: 255.0
   Default:   5.0
  Identity:  <1.0

public final DoubleProperty heightProperty
```
    The vertical dimension of the blur effect. The color information for a given pixel will be spread across a Box of the indicated height centered over the pixel. Values less than or equal to 1 will not spread the color data beyond the pixel where it originated from and so will have no effect.
