At this moment you need an external executable called emfplus.exe (http://www.imagemagick.org/download/contrib/EMFPlus.tar.gz) in your bin directory. I am working on trying to integrate this within ImageMagick but I cannot give you an ETA when this will be done. Your example above can be rewritten like this:
MagickReadSettings settings = new MagickReadSettings(); settings.Density = new MagickGeometry(288, 288); using (MagickImageCollection images = new MagickImageCollection("image.emf", settings)) { using (MagickImage image = images.Flatten()) { image.Quality = 100; // You are missing a 1? image.ColorSpace = ColorSpace.RGB; image.Resize(0.5); // implicit cast to Percentage image.ColorSpace = ColorSpace.sRGB; image.Write("image.png"); } }
