Constants

Defined Argument     Constant     Description
---------------------------------------------------------------------------
PREC                 PSTRP        String precision.  Digital PHIGS evaluates
                                  character height and width attributes.
                     PCHARP       Character precision.  Digital PHIGS
                                  evaluates each character for compliance
                                  with all other specified text attributes.
                     PSTRKP       Stroke precision.  Digital PHIGS looks for
                                  exact compliance with all specified text
                                  attributes.
