If you have IDL 5.3 or later, check out the documentation for
IDLgrClipboard, in particular the VECTOR keyword for IDLgrClipboard::Draw.
If you don't have IDL 5.3, then you're out of luck.

You need IDL 5.3 to do this.
IDL> myClipboard = obj_new('IDLgrClipboard')
IDL> myClipboard->Draw, myView, filename = 'gah.eps', vector = 1,
postscript = 1
This way you will have a nearly real vector postscript. I say "nearly"
because text will not be in postscript font : each charachter is drawn
using small triangles.
As discussed a week (or two) ago, if you have graphic atoms that
overlapp but are at a same graphic object Z value the result can be (is
?) different between a vector postscript output and a IDLgrWindow
rendering.
Later.
Nicolas.
