[magick-users] How to specify /ASCII85Decode /FlateDecode for PDF images?

[Vasile Gaburici]

Sadly "convert" doesn't seem to support chaining multiple compression
filters like the PDF spec allows. So, there doesn't seem to a way to
chain "-compress none" i.e. '/ASCII85Decode' and "-compress zip" i.e.
/FlateDecode'. This isn't a big issue...
