New Post: Image conversion in web app

You can use Magick.NET in a .NET 2.0 web application. But you cannot use Magick.NET.Web.dll because it uses 'PreApplicationStartMethodAttribute' which is only available since .NET 4.0. You need to call MagickNET.Initialize yourself.

And in response to the question you posted on the ImageMagick.NET discussions board. You could use this to remove a border from a image:

using (MagickImage image = new MagickImage("source.image"))
{
  image.Shave(borderWidth, borderWidth);
}
