[magick-users] resize problem with transparent gifs

[alexander]

hi there,
thank you for your quick answer!
sadly this doesn´t work.
well. it works great with imagemagick <= 6.2.2
but with imagemagick > 6.2.2 the output looks horrible
maybe i will have to try to look through the changesets in the 
imagemagick code to find out whats changed.
thanks and kind regards,
alexander
