 Name:         »Translate VDI colour index to colour table index«

 Opcode:       206 (Sub-Opcode 3)

 Syntax:       int16_t v_ctab_idx2vdi( int16_t handle, int16_t index 
               );

 Description:  The call v_ctab_idx2vdi converts the colour table index 
               into a VDI colour index.

                Parameter  Meaning

                handle     Workstation identifier
                index      Index for the colour table

               For resolutions up to 256 colours, index is the index 
               for the COLOR_ENTRY in the current colour table and 
               simultaneously also the actual pixel value that is 
               entererd in the bitmap. For graphic formats with more 
               than 256 colours, index continues to denote the entry 
               in the colour table; the pixel value however is output 
               by the VDI as a direct RGB value in the bitmap.

 Return value: The function returns the old VDI colour index for 
               vsl_color or similar functions

 Availability: As of NVDI 5.00.

 Group:        Colour table functions
