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

11 void gset_text_font_prec(const Gtext_font_prec *text_font_prec);
13
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 1 ASCII font (default)
20 -2 Hershey cartographic Roman
22 -3 Hershey cartographic Greek
24 -4 Hershey simplex Roman
26 -5 Hershey simplex Greek
28 -6 Hershey simplex script
30 -7 Hershey complex Roman
32 -8 Hershey complex Greek
34 -9 Hershey complex script
36 -10 Hershey complex italic
38 -11 Hershey complex Cyrillic
40 -12 Hershey duplex Roman
42 -13 Hershey triplex Roman
44 -14 Hershey triplex italic
46 -15 Hershey Gothic German
48 -16 Hershey Gothic English
50 -17 Hershey Gothic Italian
52 -18 Hershey math symbols
54 -19 Hershey symbol set 1
56 -20 Hershey symbol set 2
58 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 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 GPREC_STRING
78 String precision (good). This is the GKS default.
79 GPREC_CHAR
81 Character precision (better).
82 GPREC_STROKE
84 Stroke precision (best). This is the default for
85 NCAR GSK-0A.
86
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
95 To use the GKS C-binding routines, load the ncarg_gks and ncarg_c
96 libraries.
