Defined Argument   Constant     Description
---------------------------------------------------------------------------
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

PQCMMF returns information about the color mapping methods available on Digital PHIGS.

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
        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
        IA(1) =        Maximum number of pseudo color entries
        RL    = 0
        RA    = ()
        SL    = 0
        LSTR = 0
        STR   = ()

If CMTYP is PSUDN, there is no data record.
