Thumbnailing - preserve transparency

[Pickle]

Hi all,

I'm having a heck of a time preserving transparency when converting from vector formats (AI & EPS) to PNG thumbnails. I've tried matching the read-in colourspace, adding the "-background none" flag, setting the "-transparent cmyk(0,0,0,0)" flag - "cmyk(0,0,0,0)" being the value of "Transparent" when I call identify -verbose.

I can convert from a PNG with a transparency to another PNG with transparency - that works as expected - but when converting from an EPS, the background goes white.

What version of IM and what platform? Please read viewtopic.php?f=1&t=9620

Can you provide a link to one or more of your files so that others can review the file and test with it?
