pst-slpe – Sophisticated colour gradients

This PStricks package covers all the colour gradient functionality of pst-grad (part of the base PSTricks distribution), and provides the following facilities:

• it permits the user to specify an arbitrary number of colours, along with the points at which they are to be reached;
• it converts between RGB and HSV behind the scenes;
• it provides concentric and radial gradients;
• it provides a command \psBall that generates bullets with a three-dimensional appearance; and
• uses the xkeyval package for the extended key handling.
