How do I Use the `montage` functionality from within Magick.net

Question

I am new to Magick.net but I am trying to make a file generator. I have had it work fine from within the Linux command line (without the size I prefer though), but I need to make a .net app for use by others that don't have access to Linux, or the web (so using PHP not in question, at least not yet).

Doing something like:

montage -background none -fill black -font Helvetica-Condensed-Light -pointsize 26 label:'Foobar Controller 3.1.4.0 Installer' +set label -shadow -geometry +5+5 test_v3.png

But unsure how to use montage from within the C# .net wrapper.

using (MagickImage image = new MagickImage(new MagickColor("#000000"), 419, 39))
            {
               new Drawables()
              // Draw text on the image

But I am rather confused in how I can accomplish this.

Any advice is greatly appreciated. The documentation seems confusing since I am not doing something "standard", as the output will be previewed in an image panel with the option of saving to the file system.

Below is an example of how you would need to translate the command from montage.

using (var images = new MagickImageCollection())
{
  var readSettings = new MagickReadSettings()
  {
    BackgroundColor = MagickColors.None, // -background none
    FillColor = MagickColors.Black, // -fill black
    Font = "Helvetica-Condensed-Light", // -font Helvetica-Condensed-Light
    FontPointsize = 26 // -pointsize 26
  };

  // label:'Foobar Controller 3.1.4.0 Installer'
  var image = new MagickImage("label:Foobar Controller 3.1.4.0 Installer", readSettings);
  image.RemoveAttribute("label"); // +set label
  images.Add(image);

  var montageSettings = new MontageSettings()
  {
    BackgroundColor = MagickColors.None, // -background none
    Shadow = true, // -shadow
    Geometry = new MagickGeometry(5, 5, 0, 0) // -geometry +5+5
  };

  using (MagickImage result = images.Montage(montageSettings))
  {
    result.Write("test_v3.png");
  }
}

But because you are only using the shadow part of Montage you could also execute your code like this:

var readSettings = new MagickReadSettings()
{
   BackgroundColor = MagickColors.None,
   FillColor = MagickColors.Black,
   Font = "Helvetica-Condensed-Light",
   FontPointsize = 26
};

var label = new MagickImage("label:Foobar Controller 3.1.4.0 Installer", readSettings);
using (MagickImage shadow = label.Clone())
{
   // This is what is happening under the hood.
  shadow.Shadow(5, 5, 2.0, new Percentage(80), MagickColors.Black);
  shadow.Composite(label, CompositeOperator.Over);
  shadow.Write("test_v3.png");
}
