int get_num_luts( )
Java: int Get_num_luts( )
[Declared in "../apps/compressed_io/jp2.h"]
Returns the number of separate lookup tables managed by the palette. Note that the standard does not insist that all (or indeed any) of these lookup tables actually be used to map code-stream image components. Nor does it prevent any given LUT from being used multiple times, to map different code-stream image component samples.
0 if no palette is being used.
