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

SYNOPSIS

       CALL GSTXFP (FONT, PREC)

C-BINDING SYNOPSIS

       #include <ncarg/gks.h>

       void gset_text_font_prec(const Gtext_font_prec *text_font_prec);

DESCRIPTION

       FONT        (Integer,  Input)  - Specifies the text font to be used in subsequent calls to
                   the GTX 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 FONT described here
                   (PLOTCHAR has no need to follow the strictures that GKS imposes on font  names
                   for GSTXFP).

       PREC        (Integer,  Input)  -  Gives  the precision used in subsequent calls to the GTX
                   output primitive for font type FONT.  Options are:

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

                   1      Character precision (better).

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

USAGE

       If one accesses the Hershey fonts via GSTXFP and GTX, 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 GKS routines, load the NCAR GKS-0A library ncarg_gks.
