---------------------------------------------------------------------------
CMTYP              PTRUE        Digital PHIGS performs the identity
                                mapping.
                   PSUD         Digital PHIGS converts the colors to a
                                single integer index.
                   PSUDN        Digital PHIGS converts the colors to a set
                                of indexes.

Description

PQCMS returns the color mapping data record associated with the specified color mapping method.

Digital PHIGS Version 3.1 does not support this function.

Data Record Information

If CMTYP is PTRUE, the data record has the following format:

INTEGER IL      = 1        Number of integer values
INTEGER IA(1)              Number of true colors available
        RL      = 0
        RA      = ()
        SL      = 0
        LSTR    = ()
        STR     = ()

If CMTYP is PSUD, the data record has the following format:

INTEGER IL      = 1        Number of integer values
INTEGER IA(1)              Number of pseudo color entries available
        RL      = 0
        RA      = ()
        SL      = 0
        LSTR    = ()
        STR     = ()

If CMTYP is PSUDN, there is no data record.
