You can create a 4-bit Grayscale image as follows:
Use the GrayscaleCommand Class and convert the image to 8-bit grayscale, then use the ColorResolutionCommand Class to convert the image to 4-Bit and set the ColorResolutionCommand.PaletteFlags Property to ColorResolutionCommandPaletteFlags.Optimized.

For the 4 and 8 bit colored images, use the ColorResolutionCommand Class to convert the image to 4 or 8 Bit and set the ColorResolutionCommand.PaletteFlags Property to ColorResolutionCommandPaletteFlags.Optimized.
