Hello:

I'm working through re-learning java and would like to solicit some help.

Can anyone share some simple java code to:

1. Set up a small (say 320w x 240h) 2d window.
2. Set(color) and Read (color) of pixels within this window.

TIA for your help,
TomC

Just cause so many are heaping on Swing lately.

package pixel.test;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.ImageView;
import javafx.scene.image.PixelReader;
import javafx.scene.image.PixelWriter;
import javafx.scene.image.WritableImage;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class PixelTest extends Application {

   WritableImage image = new WritableImage(320,240);
   PixelReader pixelReader = image.getPixelReader();
   PixelWriter pixelWriter = image.getPixelWriter();

   //setPixel and readPixel left as an exercise

   @Override
   public void start(Stage primaryStage) {
     ImageView imageView = new ImageView();
     imageView.setImage(image);
     StackPane root = new StackPane();
     root.getChildren().add(imageView);
     Scene scene = new Scene(root, 320, 240);
     primaryStage.setTitle("Pixel Test");
     primaryStage.setScene(scene);
     primaryStage.show();
   }

   public static void main(String[] args) {
     launch(args);
   }
}
