You will have to draw your graphics in either a pixmap window
or in the Z graphics buffer. You can take a screen snapshot and
write the proper file by using my TVREAD procedure:


Your code will look something like this:

   thisDevice = !D.Name
   Set_Plot, 'Z'
   Plot, ....
   OPlot, ....
   XYOutS, ...
   image = TVRead(/JPEG)
   Set_Plot, thisDevice
