New Post: Working with clipping paths

I'm just getting started with Magick.NET. Unfortunately, I cannot figure out how to properly work with clipping paths. Can anyone give me an example of how to Change the Background Color and/or remove the Background?

The Clip()-method doesn't seem to do anything for me.

Also, I'm experiencing a strange bug, when writing a file. My source file is an EPS-file with a resolution of 1144x686. Doing a simple

using (MagickImage image = new MagickImage("img/34667.eps"))
            {
image.Write("img/new.eps");
            }

saves the Image as a 275x208 Image.
