Now, there's a good idea. I was just telling my class
last week about the large number of people I know who
use GhostView as their standard monitor, and they just
stared at me, dumbfounded.
But, yes, using device coordinates in PostScript is
probably not what I would recommend. Your arrays could
get, uh, large. :-)
"Life-cycle method" is a fancy way of saying the INIT
and CLEANUP methods are not called directly. They are
called indirectly when you create (OBJ_NEW) and destroy
(OBJ_DESTROY) your object.
Maybe you could show us a bit of code, so we could
suggest something reasonable.
Cheers,
David
