Program To Add Drawings To Still Frames Of Videos

Draw a circle in java in the middle of the frame?

You're going to need a JPanel with a BorderLayout layout placed in the Center of the JFrame.

Use the paintComponent() method of the JPanel to draw your oval:








import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class Program extends JFrame {

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

public Program(){
setTitle("Draw");
setSize(360, 600);
setLocationRelativeTo(null);
setDefaultCloseOperation
(JFrame.EXIT_ON_CLOSE);

MyPanel panel = new MyPanel();
panel.setLayout(new BorderLayout());

add(panel);
setVisible(true);
}

class MyPanel extends JPanel{

@Override
protected void
paintComponent(Graphics g) {
super.paintComponent(g);

g.setColor(Color.BLACK);
g.fillRect(0, 0, getWidth(),
getHeight());

g.setColor(Color.WHITE);
g.fillOval(getWidth()/2 - 45,
getHeight()/2 - 45, 90, 90);
}
}

Java: How do I reduce lag when drawing graphics?

I'm making a game using Java. So far I have an AWT Canvas (double buffered) and in my game loop I have calls to update the game model, and then draw the graphics. It works so far if I just draw the basic character bodies, but the game starts to really lag when I add more graphical details.

To elaborate, the game runs at a decent speed when just the character bodies (which are simple shapes - I use g2d.draw(new Rectangle2D.Double(...)), for example).

However, when I add details, such as the eyes (essentially four more circles - g2d.draw(new Ellipse2D.Double(...)) ), then the game starts lagging like crazy.

Why is this happening and what can I do to reduce lag as much as possible?
