New Post: Poor quality with Resize-method of Magick.NET

You are correct. I am using the following version im convert.exe (output of 'convert.exe --version')

Version: ImageMagick 6.8.9-6 Q8 x64 2014-07-22 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2014 ImageMagick Studio LLC
Features: DPC Modules OpenMP
Delegates: bzlib cairo freetype jbig jng jp2 jpeg lcms lqr pangocairo png ps rsvg tiff webp xml zlib

I switched to the corresponding nuget-package of Magick.NET (Install-Package Magick.NET-Q8-AnyCPU -Version 6.8.9.601).

And voila: the quality is much better and the same as the convert.exe. It seems to be a bug in version 7!
