Well, I now understand your point: you would like to create an high
resolution Postscript output like by using the "set_plot,'PS'" DG
command.
But I am afraid that the graphic.print/save command as well as the
"print' button on graphic window is just able to create a copy of the
window from your screen, with the same low resolution. As you can see
by opening the EPS file and looking at the BoundingBox PS statement.
This explains why "my" plot (640x512) was not too much clipped in
GSVIEW. Yours was certainly a lot bigger.
People from ITTVIS have now to explain us how one can make a true,
high resolution PostScript drawing by using NG !
Cheers,
alx.
