To subscribers of the xforms list from "Robert S. Mallozzi" <mallors@crazyhorse.msfc.nasa.gov> :

I just tried the new fl_object_ps_dump(). It is a great new
feature, but there seem to be some problems.

1. If I use FL_WHITE for the xyplot foreground color, nothing is visible
in the PS file. For the xyplot object, use

fl_set_object_color(obj, FL_BLACK, FL_WHITE);

and then the pen color in the PS file is white, and the background is
also white. Even if one sets FLPS_COLOR, the background seems always
to be set to white, which is (probably) OK, so I guess there should
be a check to see if the foreground is white, and if so, set it to

2. I tried to plot a dataset of over 4000 points (dataset was 4067),
and it appears in the xyplot just fine, fl_object_ps_dump() calls
OK, but I get the following error if I try to view the PS file
(with ghostview or gv):
