Thanks for the hint using /VECTOR. I even tried it with the
live_tools:
IDL> live_print, /vector, /dialog
and it gave me a nice vector ps file. However,
IDL> live_print, /vector, FILENAME='idl.ps', /POSTSCRIPT, /VECTOR
failed since FILENAME and POSTSCRIPT keywords were unknown.
Any idea to directly print an insight/live_plot image to ps-file or
eps-file?
Thanks
