BitsPerPixel # get (RasterImage)
Number of bits per pixel of this RasterImage.
The RasterImage object supports image data of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48 and 64 bits per pixel
A 16-bpp image may be color or grayscale. If you are working with a 16-bit grayscale image, then use RasterByteOrder.Gray when creating the image. By default, the Order for a 16-bit image will be set to RasterByteOrder.Bgr.
