The following is copied directly from the getStyle section of the GD
docs at <http://search.cpan.org/~lds/GD-2.39/GD.pm>:

# Set a style consisting of 4 pixels of yellow,
# 4 pixels of blue, and a 2 pixel gap
$myImage->setStyle($yellow,$yellow,$yellow,$yellow,
$blue,$blue,$blue,$blue,
gdTransparent,gdTransparent);
$myImage->arc(50,50,25,25,0,360,gdStyled);

You could probably also use brushes instead. Anyway all the
information is really there in the docs. If you're unable to create a
working script from that, you may want to post at least what you've
got now and what you're having difficulty with *exactly*. Just
claiming GD doesn't do what you want when it clearly does and even
provide examples in the docs isn't helping.

Take some time to read the full manpage linked above, it's not that
big and you should be able to figure it out yourself.

I feel sorry for not understanding what "holes" refer to... Not
complimenting Matlab, but I am used to its elegant library to provide
intuitive and powerful functions... Certainly, GD provides a greater control
over how wide the holes can be...

If you need to do this without X, you might want to look at the Cairo
module
http://cairographics.org/samples/

You can save them to many file formats. Gtk2's graphics are based
on Cairo.

Also the OP may want to consider Matlab's own scripting abilities which
are pretty decent.

Really? I have only cursory experience with Matlab, which was used in
a genomics course I took, but I wasn't very impressed. Guess I didn't
look closely enough at it.
