Xamos

Hi,
Anybody using Xamos.
Can it use pngs with their full Alpha Channels? I got it to load a 256 colour png with 1 colour transparent, which worked but I would like to use regular pngs with their full 256 gray scale Alpha Channel. I would really like to use apngs (Vamp can load & run apngs with the help of a apng Hollywood plugin).
I am also looking for more examples (to help me understand it), are there any out there?
Could some kind Samaritan post some simple examples (nicely commented, explaining what's going on). It seems quite capable, and runs nicely on an old pc given new life under Aros
