[magick-users] convert gif to png, and lost transparency

[Fred Weinhaus]

You have a type pseudocolor image with transparency. This works for 
me to keep the png the same pseudocolor with transparency.

convert powerlogo.gif PNG8:powerlogo.png

or to convert to 32bit (RGBA)

convert powerlogo.gif PNG32:powerlogo.png


The default convert to png is equivalent to PNG24 (24-bit RGB no alpha)


see http://www.imagemagick.org/Usage/formats/#png_formats
