Please enter a bug report with the code
and describe exactly what you mean by bad (ie. it's the black circle lines,
right?).  Thanks.

Hi ! 
I'm using eclipse 3.1 on Windows XP, when I draw round rectangles
sometimes the rounded corners are drawn badly specially when Transform
is used. 
Here is a snapshot of bad drawing :

Does anyone have seen yet ? 

Thanks for any informations. 

Arnaud. 

PS: used code to reproduce problem: 

package test1; 

import org.eclipse.swt.events.PaintEvent; 
import org.eclipse.swt.events.PaintListener; 
import org.eclipse.swt.graphics.Color; 
import org.eclipse.swt.graphics.Transform; 
import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Shell; 

public class RoundRect 
{ 
        public static void main(String[] args) 
        { 
                Display disp =
new Display(); 
                Shell shell = new
Shell( disp ); 
                shell.setSize(
400, 300 ); 
        shell.addPaintListener( new PaintListener()
{ 
                    
   public void paintControl(PaintEvent e) {
                    
           Transform tr = new Transform(
e.display ); 
//same effect:                
               tr.translate( 0,0
); 
                    
           tr.translate( 5,5 );
                    
           e.gc.setTransform( tr );
                    
           e.gc.setBackground( new Color(null,255,0,0));
                    
           e.gc.fillRoundRectangle( 0,0,
142, 90, 90,90 );                
               
                    
           e.gc.drawRoundRectangle( 0,0,
142, 90, 90,90 ); 
                    
           e.gc.setTransform( null );
                    
           tr.dispose();
                    
   } 
        }); 
        
        shell.open (); 
        while (!shell.isDisposed ()) {
                if (!disp.readAndDispatch
()) 
                    
   disp.sleep (); 
        } 
        disp.dispose (); 
        }
