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.
