Gets the value indicating whether the image data was in a different byte-order than the host computer.
Note that ReadTile, ReadEncodedTile, ReadEncodedStrip and O:BitMiracle.LibTiff.Classic.Tiff.ReadScanline methods already normally perform byte swapping to local host order if needed.
Also note that ReadRawTile and ReadRawStrip do not perform byte swapping to local host order.
