true if the image data was saved LSB, false if the image data was saved MSB.
This property is used when loading raw data and some formats that support motorola byte order. To load raw 12-bit and 16-bit extended grayscale images, set the CodecsLoadInformationEventArgs.Order property to RasterByteOrder.Gray and the CodecsLoadInformationEventArgs.LeastSignificantBitFirst Property accordingly.
