NAME

       gset_text_font_prec (Set text font and precision) - sets the text font and precision.

SYNOPSIS

       #include <ncarg/gks.h>

       void gset_text_font_prec(const Gtext_font_prec *text_font_prec);

DESCRIPTION

       text_font_prec.font
                   (Gint,  Input)  Specifies  the text font to be used in subsequent calls to the
                   gtext output primitive. Options are:

                     1    ASCII font (default)

                    -2    Hershey cartographic Roman

                    -3    Hershey cartographic Greek

                    -4    Hershey simplex Roman

                    -5    Hershey simplex Greek

                    -6    Hershey simplex script

                    -7    Hershey complex Roman

                    -8    Hershey complex Greek

                    -9    Hershey complex script

                   -10    Hershey complex italic

                   -11    Hershey complex Cyrillic

                   -12    Hershey duplex Roman

                   -13    Hershey triplex Roman

                   -14    Hershey triplex italic

                   -15    Hershey Gothic German

                   -16    Hershey Gothic English

                   -17    Hershey Gothic Italian

                   -18    Hershey math symbols

                   -19    Hershey symbol set 1

                   -20    Hershey symbol set 2

                          The  Hershey  fonts  are  not  standardized  by  GKS  but  are  locally
                          implemented  in NCAR GKS-0A. GKS requires that such locally implemented
                          fonts be assigned negative font numbers. To  view  the  Hershey  fonts,
                          look  at the plots produced from the PLOTCHAR example (execute "ncargex
                          epltch" to get a metafile)  and  examine  the  plot  titled  "PLCHHQ  -
                          FONTCAP DATABASES ADDED 6/90".  The font numbers there are the absolute
                          values of the value for text_font_prec.font  described  here  (PLOTCHAR
                          has no need to follow the structures that GKS imposes on font names for
                          gset_text_font_prec).

       text_font_prec.prec
                   (Input) Gives the precision used in  subsequent  calls  to  the  gtext  output
                   primitive for font type text_font_prec.font.  Options are:

                   GPREC_STRING
                          String precision (good). This is the GKS default.

                   GPREC_CHAR
                          Character precision (better).

                   GPREC_STROKE
                          Stroke precision (best). This is the default for NCAR GSK-0A.

USAGE

       If  one  accesses the Hershey fonts via gset_text_font_prec and gtext, then the characters
       are not stroked until viewing time.  If one accesses the Hershey fonts via PLOTCHAR,  then
       the  characters are stroked by PLOTCHAR itself.  This can make a significant difference in
       metafile sizes.

ACCESS

       To use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries.
