      Description



      Name: boT120536 Date: 09/04/2001


      java version "1.4.0-beta2"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta2-b77)
      Java HotSpot(TM) Client VM (build 1.4.0-beta2-b77, mixed mode)

      I was messing around with displaying text using the Java fonts and I noticed
      that when I would set the rotation of the Graphics2D object and then draw the
      text, the text would not display exactly where i wanted it to...close, but not
      exact. But if the rotation was 0 degrees, it WOULD display exactly where i
      expected it.

      So I switched back to the 1.3.1 version of the JDK....and it works correctly!
      The text draws exactly where i tell it to draw...not shifted based on rotation
      angle.

      For further evidence...I draw a rectangle at the XY coordinate that i tell the
      text to draw. At 0 degrees, the rectantle and text show up at the same spot.
      Rotated about a given point by 90 degrees, the rectangle and text no longer
      exactly match...the rectangle is where i expect it to be...but the text is not.

      HERE IS A PROGRAM THAT DEMONSTRATES THE PROBLEM...Note that it works correctly
      in 1.3.1...incorrectly in 1.4 beta 2:

          public static void main(String args[])
          {
              JFrame jfrm = new JFrame("Rotate Text Problem");
              Component jcmp = (Component) jfrm.getContentPane();
              Container jcnt = (Container) jcmp;
              jcnt.add( new JPanel()
                      {
                          public void paint(Graphics g)
                          {
                              Graphics2D drw = (Graphics2D) g;

                              Font f = new Font("Times",Font.PLAIN, 14);

                              drw.setFont(f);
                              drw.setColor(Color.black);

                              drw.drawString("Kelly Harmon",200,200);

                              drw.drawRect(197,197,6,6);


                              AffineTransform affTrans = new AffineTransform();

                              affTrans.setToIdentity();

                              affTrans.rotate(4.71,100,100);

                              drw.setTransform(affTrans);

                              drw.drawString("Kelly Harmon",110,110);

                              drw.drawRect(107,107,6,6);

                              // done!
                          }
                      });

                  jcnt.addMouseListener( new MouseAdapter()
                      {
                          public void mousePressed(MouseEvent e)
                          {
                              _bPass1=false;
                              Component comp = (Component) e.getSource();
                              comp.repaint();
                          }
                          
                      });

              jfrm.setBounds (0,0,800,600);
              jfrm.setVisible(true);

          }
      }
