JavaFX: GaussianBlur Effect

 

GaussianBlur class is used to create a blur effect using a Gaussian convolution kernel, with a configurable radius.

 

GaussianBlur class provides below constructors to define GaussianBlur object.

 

public GaussianBlur()

public GaussianBlur(double radius)

radius: Specifies the radius of the blur kernel

 

FXML Example

         <Text fx:id = "text1" text="Learning JavaFX"  fill="white"

                  style="-fx-font-weight: bold; -fx-font-size: 50; -fx-font-family: Verdana; -fx-font-style: italic"

                  stroke="black" strokeWidth="2"

                  x="50" y = "50" effect="$shadow1">

                 

                  <GaussianBlur fx:id = "shadow1" radius="3"/>

         </Text>
