[JAVA2D] Could not draw into a Graphics2D object (created from BufferedIma ge)after the 2D object rotated

[Jianfan (Jeff) Wang]

Hi,

         I had a program that I could draw into a graphics2D objects created by 
BufferedImage object.  The problem is that I could not drawString after I did 
Graphics2D rotate.  Could anybody help?  The following is the piece of code that works 
or does not work.

  Graphics2D g2 = bi.createGraphics();

  // The following codes works
       Date date = new Date(System.currentTimeMillis());
       g2.drawString("Date: " + date.toString(), 80, 80);;
       g2.drawString("Subgroup", 20, 20);

  // The following code does not work, I could not draw anything by different
  // Rotated locations
       AffineTransform at = new AffineTransform();
       at.rotate(Math.PI/2);
       g2.setTransform(at);

       g2.drawString("Sample Mean", -140, -30);
       g2.drawString("Sample Mean", -140, 30);
       g2.drawString("Sample Mean", 140, 30);
       g2.drawString("Sample Mean", 140, -30);  // correct one

     Thanks.
