Class Bloom

java.lang.Object
  • javafx.scene.effect.Effect
    • javafx.scene.effect.Bloom


public class Bloom
extends Effect
A high-level effect that makes brighter portions of the input image appear to glow, based on a configurable threshold.

Example:

Bloom bloom = new Bloom();
 bloom.setThreshold(0.1);

 Rectangle rect = new Rectangle();
 rect.setX(10);
 rect.setY(10);
 rect.setWidth(160);
 rect.setHeight(80);
 rect.setFill(Color.DARKSLATEBLUE);

 Text text = new Text();
 text.setText("Bloom!");
 text.setFill(Color.ALICEBLUE);
 text.setFont(Font.font(null, FontWeight.BOLD, 40));
 text.setX(25);
 text.setY(65);
 text.setEffect(bloom);

The code above produces the following:
