New Post: Bitmap with bit depth 1

using (MagickImage image = new MagickImage("logo:"))
{
  // First reduce the colors
  image.ColorType = ColorType.Bilevel;

  // Or use Quantize/*
  image.Quantize(new QuantizeSettings()
  {
    Colors = 2
  });
  */// Tell image to use a color map
  image.ClassType = ClassType.Pseudo; 

  // HACK! For now you will have to add the code below, this will be fixed in the next release
  image.ChangeColorSpace(ColorSpace.sRGB);

  // Write 1 bit bmp
  image.Write(@"C:\logo.bmp");
}
