JavaFX: ColorAdjust effect

ColorAdjust effect is used to adjust the color of an image by adjusting hue, saturation, brightness, and contrast.

 

Step 1: Get an instance of ColorAdjust.

ColorAdjust colorAdjust = new ColorAdjust();

colorAdjust.setHue(0.7);

colorAdjust.setContrast(0.2);

colorAdjust.setBrightneess(0.7);

colorAdjust.setSaturation(0.4);

 

Step 2: Get an Image instance.

String filename = "house.png";

InputStream in = this.getClass().getClassLoader().getResourceAsStream(filename);

Image image = new Image(in);

 

Step 3: Get an instance of ImageView instance.

ImageView imageView = new ImageView(image);

imageView.setFitWidth(400);

imageView.setFitHeight(400);

imageView.setPreserveRatio(true);

imageView.setEffect(colorAdjust);

 

Step 4: Add ImageView to the Group

Group group = new Group();

group.getChildren().add(imageView);

 

Step 5: Define Scene instance and set it to the stage.

Scene scene = new Scene(group, 400, 400);

primaryStage.setTitle("Color Adjust Demo");

primaryStage.setScene(scene);

primaryStage.show();
