Circle looks bad

I'm trying to draw a good looking circle with fillOval(0,0,12,12) but it looks quite bad.
It looks more like a rounded rectangle with little points sticking out.
Even the "Instant Graemlins" in this message board look more circular.
Am I doing something wrong or is this a limitation?

hi,
i think you should use antialising for smoother edges.

sample2
(this are the first google results, keywords "java antialiasing")
good luck

Hi,
It sure looks like a circle to me at 12x12. Maybe if you go smaller, it looks like a rounded rectangle.
One way to make the circle look real smooth is to use anti-aliasing. Refer to the code attached. One shows a circle w/o anti-aliasing and the other with it.
Hope that helps.
regards,
Raj

        setPreferredSize( new Dimension(100,100));
    }

    {
        if ( isAntialiased )
            ((Graphics2D) g).setRenderingHint( RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON );
        g.fillOval( 0, 0, 100, 100 );        
    }
    
    public static void main(String[] args) {
        JFrame f = new JFrame( "TestCircle" );
        f.getContentPane().setLayout( new FlowLayout() );
        f.getContentPane().add( new TestCircle( false ));
        f.getContentPane().add( new TestCircle( true ));       
        f.setSize(200,250);
        f.setVisible( true );
    }
}

Thanks for the suggestions, but I forgot to mention that I need this to work with Java 1.1, thus no Graphics 2D or Swing...

Well, then you'll have to fake antialiasing yourself... The following code doesn't do perfect antialiasing, but it should give you an idea of what to do...

import java.awt.Color;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
  
public class SmoothCircles extends Frame {
    
    public void paint( Graphics g ) {
        // The color you want the oval to be.
        Color c = Color.red;
        
        // The size you want the oval to be.
        int size = 12;
        
        // Calculate a lighter color.
        int red = Math.max( 255 / 2, Math.min( c.getRed() * 2, 255 ) );
        int green = Math.max( 255/ 2, Math.min( c.getGreen() * 2, 255 ) );
        int blue = Math.max( 255 / 2, Math.min( c.getBlue() * 2, 255 ) );
        Color lightColor = new Color( red, green, blue );
        
        // Draw the outside oval.
        g.setColor( lightColor );
        g.fillOval( ( getWidth() - (size) ) / 2, ( getHeight() - (size) ) / 2, size, size );
        
        // Draw the inside oval.
        g.setColor( c );
        g.fillOval( ( getWidth() - ( size - 2 ) ) / 2, ( getHeight() - (size - 2) ) / 2, size- 2, size - 2 );
    }
    
    public static void main( String[] args ) {
        Frame f = new SmoothCircles();
        f.addWindowListener( new WindowAdapter() {
            public void windowClosing( WindowEvent e ) {
                System.exit( 0 );
            }
        } );
        f.setSize( 300, 300 );
        f.setVisible( true );
    }
}

Thanks Nate, that does look a lot better.
Although, I can still get a better looking circle in Photoshop.
I might just load a transparent gif of a circle instead...
