Constants

Defined Argument     Constant     Description
---------------------------------------------------------------------------
TYPE                 PSET         Use the exact state list values.
                     PREALI       Use the values approximated by the
                                  graphics handler.
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.

Description

PQTXR queries the workstation state list and, for the specified text index, returns values for the following:

•Text font and precision values

•Character expansion factor

•Character spacing

•Text color index

If the specified text index is not in the text bundle table on the specified workstation, and the specified type of returned values is PREALI, Digital PHIGS returns the representation for text index 1.  (See the Device Specifics Reference Manual for DEC GKS and DEC PHIGS for workstation-specific information.)
