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:
http://www.dfanning.com/programs/tvread.pro
Your code will look something like this:
thisDevice = !D.Name
Set_Plot, 'Z'
Plot, ....
OPlot, ....
XYOutS, ...
image = TVRead(/JPEG)
Set_Plot, thisDevice
Cheers,
David

hy,
Thank you for your help and for your program.
I will try it in the next days and I will give you the result of my tests.
( and perhaps others questions if I've failed though I hope not)
