/// \brief
/// The RasterDataModelType enumeration specifies the type of
/// data within each pixel. In all cases the data is 'packed', that is,
/// adjacent pixels are contiguous in memory with no unused bits between
/// them, except at the end of a row, where the row is padded to a
/// byte boundary. For example, four bit grayscale data (BitsPerPixel=4)
/// would be packed two pixels to a byte, and a row would be padded with
/// four bits if the image width was odd. Tri-colour or four channel data
/// is also organized adjacently in memory, with no intervening padding
/// except at the ends of rows. For example, eight bit RGB (BitsPerPixel=24)
/// occupies three bytes per pixel, and would never need padding at the
/// end of a row. Multiband data (i.e. RGB) has the same number of bits
/// allocated to each band, so for example RGBT data with eight bits for red,
/// would also have eight bits for each of the three other bands totaling
/// thirty-two bits (BitsPerPixel=32).
