how to draw arrows in PHP using GD function?

Hi folks,
I'm a newbie to doing images and graphics in PHP. I would appreciate
your help in the following:

1. Is there a function to draw arrowed lines in PHP?
2. Is there a way I can label a circle in PHP? Actually for the circle
I am using the imageellipse() function and it works. How do I get the
description inside the circle, i.e, Circle A, Circle B, etc?

Thanks heaps,
Da Walrus

Graphics is about manipulating primitives and packaging a bunch in a
parameratized object which can be used in turn as building blocks.

This ng isn't really the right place to discuss graphics methods.
However if you don't get a satisfactory answer then email me for some
java code which you can deconstruct.
