Re: Using -quiet through STL API

Hi,

you are totally right: "GraphicsMagick no longer produces such annoying 
warnings."

When I installed the python module pgmagick I expected it to depend on 
libgraphicsmagick++, but as it uses the ImageMagick interface, it seemed 
to be happy with libmagick++, so I didn't notice the fact, that I 
accidentally used ImageMagick on the dev machine instead of GraphicsMagick.

Everything is working fine now after I removed all imagick-magick 
packages, installed just libgraphicsmagick++3 and reinstalled python 
pgmagick (no more *core, *wand and whatever packages...).

Thanks and kind regards
Marten
