Class Blend

java.lang.Object
javafx.scene.effect.Effect
javafx.scene.effect.Blend
public class Blend extends Effect
An effect that blends the two inputs together using one of the pre-defined BlendModes.

Example: 


 Blend blend = new Blend();
 blend.setMode(BlendMode.COLOR_BURN);

 ColorInput colorInput = new ColorInput();
 colorInput.setPaint(Color.STEELBLUE);
 colorInput.setX(10);
 colorInput.setY(10);
 colorInput.setWidth(100);
 colorInput.setHeight(180);

 blend.setTopInput(colorInput);

 Rectangle rect = new Rectangle();
 rect.setWidth(220);
 rect.setHeight(100);
 Stop[] stops = new Stop[]{new Stop(0, Color.LIGHTSTEELBLUE), new Stop(1, Color.PALEGREEN)};
 LinearGradient lg = new LinearGradient(0, 0, 0.25, 0.25, true, CycleMethod.REFLECT, stops);
 rect.setFill(lg);

 Text text = new Text();
 text.setX(15);
 text.setY(65);
 text.setFill(Color.PALEVIOLETRED);
 text.setText("COLOR_BURN");
 text.setFont(Font.font(null, FontWeight.BOLD, 30));

 Group g = new Group();
 g.setEffect(blend);
 g.getChildren().addAll(rect, text);

The code above produces the following:

The visual effect of blending color, gradient and text

Since:
JavaFX 2.0
