I thought I did exactly that and copied all these files into the xypic
folder plus into my working directory. It ain't working though and still
can't find that xypdf option.

Yes, it works. Thanks again. Meanwhile I have gotten pretty impressive
results.

Right now I am trying to draw a circle solidly filled with color but without
a border. Was doing

\newxyColor{Nbackgrnd}{1 1 0.77}{rgb}{}             % Neutral Background
Color - Lighter Orange
...
(0,195)*+<30pc>[o**:Nbackgrnd]{    };

but it still puts some outline around that circle. I thought without an [F]
it was supposed not to frame it. Do you know what the right syntax is?

Also, I am drawing huge posters where I need extra thick outlines around
some other object (for instance certain boxes) to make them more visible.
The thicker option didn't work as I thought

    (0,-7)*+[F**:Nbackgrnd:thicker:<5pt>]{
    X = \dots
    };

BTW: That thicker option worked pretty good though with the curve command

    { "O-KB-EF" ; "O-KB-G0" **[O_font][thicker][thicker][thicker]\crv{
(-90,-60) } ?>*\dir{>} };

and placed just the right emphasis on these splines.

Thanks,

Joe
