DESCRIPTION

15       text_font_prec.font
16                   (Gint, Input) Specifies the text font to be used in  subse‐
17                   quent calls to the gtext output primitive. Options are:
18
19                     1    ASCII font (default)

21                    -2    Hershey cartographic Roman

42
43                   -13    Hershey triplex Roman
44
45                   -14    Hershey triplex italic

56
57                   -20    Hershey symbol set 2
58
59                          The  Hershey  fonts  are not standardized by GKS but
60                          are locally implemented in NCAR GKS-0A. GKS requires
61                          that such locally implemented fonts be assigned neg‐
62                          ative font numbers. To view the Hershey fonts,  look
63                          at  the  plots  produced  from  the PLOTCHAR example
64                          (execute "ncargex epltch" to  get  a  metafile)  and
65                          examine  the plot titled "PLCHHQ - FONTCAP DATABASES
66                          ADDED 6/90".  The font numbers there are  the  abso‐
67                          lute  values  of  the  value for text_font_prec.font
68                          described here (PLOTCHAR has no need to  follow  the
69                          structures  that  GKS  imposes  on  font  names  for
70                          gset_text_font_prec).
71
72       text_font_prec.prec
73                   (Input) Gives the precision used in subsequent calls to the
74                   gtext  output  primitive for font type text_font_prec.font.
75                   Options are:
76
77                   GPREC_STRING
78                          String precision (good). This is the GKS default.
79
80                   GPREC_CHAR
81                          Character precision (better).
82
83                   GPREC_STROKE
84                          Stroke precision (best). This  is  the  default  for
85                          NCAR GSK-0A.
86

USAGE

88       If  one  accesses  the Hershey fonts via gset_text_font_prec and gtext,
89       then the characters  are  not  stroked  until  viewing  time.   If  one
90       accesses  the  Hershey  fonts  via  PLOTCHAR,  then  the characters are
91       stroked by PLOTCHAR itself.  This can make a significant difference  in
92       metafile sizes.
93

ACCESS

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