Thumbnailing - preserve transparency
Posted: 2013-06-06T12:14:16-07:00
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.
