[JAVA2D] Clipboard, print, and Save-to-jpeg problem

[Olsen Chris]

Hello All --

  I am experiencing a vexing problem trying to send contents of a
Component to the clipboard, printer, or save-to-jpeg.  All of my
procedures use the drawPage method below to send the graphs to the
targets.  I have been able to successfully get contents to each of these
targets, but a problem intermittently occurs; that is it occurs with
some graphs and not with others.  Sometimes the text (using drawString)
gets lost on the way to the clipboard, printer, and save-to-jpeg,
leaving a textless graph.

  In some cases simply rearranging the calls (e.g. drawStrings performed
after other graphics) is successful, and other times no.  I have
included what I hope is representative code.  The drawStringInfo
basically draws text, and the drawHorizScale basically draws lines.

  I feel there must be some general principle in the painting (or
wherever) that I'm not understanding.  All my graphs get to the screen
w/o problem one!  Does this problem ring a bell with anyone?  (And, more
importantly, does a solution come with the ringing??)

  Thank you in advance for any help, and thanks to all those I have
learned so much from as I lurk...

public void drawPage(Graphics2D g2)
   {
      g2.setFont(new Font("Monospaced", Font.BOLD, 12));
      drawHorizScale(g2);
      drawStringInfo(g2);       
   }
  
    private void drawStringInfo(Graphics2D g2)
   {  
      g2.drawString("Bldg = " + bldgName, 10, 20);
      g2.drawString("Tchr = " + tchrName, 10, 35);
      g2.drawString("****    Item Statistics    ****", 50, 50);
      g2.drawString("***   p-Values vs. Building Residuals   ***", 380,
50); 
      g2.drawString("Itm   BRes   pVal", 15, 100);
      g2.drawString("Itm   BRes   pVal", 160, 100);
      g2.drawString("Building Residual", 500, 580);
      return;
   }


public void drawHorizScale(Graphics2D g2)
  {                
     g2.drawLine(smallExtent, horizLineLevel, largeExtent,
horizLineLevel);
       
     //   Draw small x ticks      
     for (double hMark = startPrintScale; hMark < stopPrintScale; hMark
= hMark + smallTickInterval)
     {
        if ((loEndOfScale <= hMark) && (hMark <= hiEndOfScale))
        {
           int screenXCoord = getScreenX(hMark);   
           g2.drawLine(screenXCoord, horizLineLevel, screenXCoord,
horizLineLevel + 5);
        }
     }     
}
