(I did switch the variable to Alpha=GOOD).
Apologies to Source for any confusion. Based on the problems I have found with akPNG I would also recommend WarpPNG (WarpDT).

I think that both AK and Warp datatypes support the alpha channel. The major problem is that the super class, picture.datatype, does not preserve it. That's why it works on AfA, but not on 3.x.
Maybe that WarpDT converts the alpha channel into a mask (each pixel either fully transparent or fully opaque, no partial transparency). This should work with any picture.datatype, but does not give the full quality if alpha is supported (i.e. with AfA).
