Are you sure it wouldn't be faster to create the buttons in Fireworks?

Forgotten my high school math. I'm creating bevels and gradients
using the
imagedata and HSV values - so I change the velocity (and/or
saturation) of
the HSV values to simulate lighting on a beveled surface - to get the
appearance of a 3D rounded button... hope you get the idea - now
what I need
is the maths for various types of curve and i need to be able to
skew these
curves to simulate light coming from an angle...
Does anyone know a useful web source for the math needed here - I
guess its
log and or sign based curves?
