Internally in ImageMagick there is a way to monitor progress of certain methods. I have not yet exposed this method in the C# API. I am now doing a huge rewrite of Magick.NET to use P/Invoke instead of CLI/C++ but I can add this when that is done. I will create an issue for this so I won't forget this :)
