JavaFX: Glow effect

Glow is a high-level effect that makes the input image appear to glow, based on a configurable threshold.

 

Glow class provides following constructors to get an instance of Glow.

 

public Glow()

public Glow(double level)

'level' specifies the level value, which controls the intensity of the glow effect. Level is in range of 0 to 1, default value is 0.3. Value 0 specifies, no pixels glow, value 1 specifies all pixels should glow.

 

Example

	<Text fx:id = "text1" text="JavaFX"
	style="-fx-font-weight: bold; -fx-font-size: 50; -fx-font-family: Verdana; -fx-font-style: italic"
	stroke="darkblue" strokeWidth="2" 
	underline="true"
	fill="yellow"
	effect="$glowEffect1">
	
		<Glow fx:id="glowEffect1" level="1.0f" />
	</Text>
