FCL-Image is quite powerful (although notably slow), it is mostly suitable for my needs. I've got it writing a solid black PNG file just fine with the help of the wiki example, but is it possible to create a memory image with an alpha channel and have it save the PNG as such? I can't manage to find anything in the docs about this possibility.
