[magick-users] 1-bit per channel PDF?

[Vasile Gaburici]

That does work, but the compression method used in the pdf is
/CCITTFaxDecode. I'm trying to avoid that because Acrobat 8 has a
stupid bug and displays these images blurred sometimes, even those it
produced itself via "Optimize Scanned PDF", although other pdf viewers
display them just fine. Unfortunately just changing your command to
"-compress zip" doesn't produce 1-bit images anymore, even with
"+matte -monochrome". FYI: the original 1-bit /FlatDecode was produced
by "wPDF by WPCubed GmbH" running inside some scanner at a library.
