JavaFX – Glow Effect


This sample is just to demonstrate how easy it is to add an effect to a Node.
First we initialize the Glow effect as shown below. The level attribute is bound to glowLevel variable so as to change the glow value at runtime.


var glowLevel = 0.0;
var glow = Glow {
    level: bind glowLevel
}

Now we will instantiate an ImageView and load the Image as shown below.


var imageView = ImageView {
    image: Image {
        url: "{__DIR__}images/light.jpg"
    }
    effect: bind glow
}

Create a Timeline which will run 5 times with auto-reverse. This Timeline is used for updating the value of glowLevel.


var timeline = Timeline {
    repeatCount: 15
    autoReverse: true
    keyFrames: [
        KeyFrame {
            time: 0s
            values: glowLevel => 0.0 ]
        },
        KeyFrame {
            time: 3s
            values: glowLevel => 0.85 ]
        }
    ]
}
timeline.play();
