Class GaussianBlur

java.lang.Object
javafx.scene.effect.Effect
javafx.scene.effect.GaussianBlur
public class GaussianBlur
extends Effect
A blur effect using a Gaussian convolution kernel, with a configurable radius.

Example:


 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(new GaussianBlur());
 

The code above produces the following:

The visual effect of GaussianBlur
 on text

Since:
JavaFX 2.0
