[magick-users] Transparency problem when converting png from 24-bit to 8-bit

[Fred Weinhaus]

I cannot tell what is happening as your links don't work.

But IM PNG8 supports only boolean transparency. see 
http://www.imagemagick.org/Usage/formats/#png_formats

don't know if that is your problem.

Also are you on an old version of IM? What version? Perhaps it had a 
bug. The current version is 6.5.2-3
