I am trying to use the AutoBinarizeCommand (Leadtools.ImageProcessing.Core), but the examples in the documentations are actually for the BlankPageDetectorCommand command, and I can't find any previous posts on this.

The command only has a few members so I would assume I am using it correctly, but I am getting a 'document capability is required' exception when I run the command. The documentation only says that
  • This command does not support 12- or 16-bit grayscale or 48- or 64-bit color
    images, but will not throw an exception.
  • This command does not support signed
    data images.
  • This command does not support 32-bit grayscale images.
I am trying to run the command on a raster image

                Dim command4 As AutoBinarizeCommand = New AutoBinarizeCommand
                command4.Factor = Val(txtInput.Text)

(rivView2.is a RasterImageViewer)

You are right. The .Net documentation doesn't mention that this function is only available in the Document and Medical Imaging toolkits.
To use this function, you have to unlock the document support in your code.
Try to use this function by using the following code:
AutoBinarizeCommand AutoBinarize = new AutoBinarizeCommand();
AutoBinarize.Flags = AutoBinarizeCommandFlags.UseAutoPreProcessing | AutoBinarizeCommandFlags.UseAutoThreshold;
AutoBinarize.Factor = 0;
