DESCRIPTION

18       FONT        (Integer, Input) - Specifies the text font to  be  used  in
19                   subsequent calls to the GTX output primitive. Options are:
20
21                     1    ASCII font (default)
22
23                    -2    Hershey cartographic Roman
24
25                    -3    Hershey cartographic Greek
26
27                    -4    Hershey simplex Roman
28
29                    -5    Hershey simplex Greek
30
31                    -6    Hershey simplex script
32
33                    -7    Hershey complex Roman
34
35                    -8    Hershey complex Greek

42
43                   -12    Hershey duplex Roman
44
45                   -13    Hershey triplex Roman
46
47                   -14    Hershey triplex italic
48
49                   -15    Hershey Gothic German
50
51                   -16    Hershey Gothic English
52
53                   -17    Hershey Gothic Italian
54
55                   -18    Hershey math symbols
56
57                   -19    Hershey symbol set 1
58
59                   -20    Hershey symbol set 2
60
61                   The  Hershey  fonts  are  not  standardized  by GKS but are
62                   locally implemented in NCAR GKS-0A. GKS requires that  such
63                   locally  implemented  fonts  be assigned negative font num‐
64                   bers. To view the Hershey fonts, look at the plots produced
65                   from  the PLOTCHAR example (execute "ncargex epltch" to get
66                   a metafile) and examine the plot titled "PLCHHQ  -  FONTCAP
67                   DATABASES  ADDED  6/90".   The  font  numbers there are the
68                   absolute values  of  the  value  for  FONT  described  here
69                   (PLOTCHAR  has  no  need  to follow the strictures that GKS
70                   imposes on font names for GSTXFP).
71
72       PREC        (Integer, Input) - Gives the precision used  in  subsequent
73                   calls  to  the  GTX  output  primitive  for font type FONT.
74                   Options are:
75
76                   0      String precision (good). This is the GKS default.
77
78                   1      Character precision (better).
79
80                   2      Stroke precision (best). This  is  the  default  for
81                          NCAR GSK-0A.
82

USAGE

84       If  one accesses the Hershey fonts via GSTXFP and GTX, then the charac‐
85       ters are not stroked until viewing time.  If one accesses  the  Hershey
86       fonts via PLOTCHAR, then the characters are stroked by PLOTCHAR itself.
87       This can make a significant difference in metafile sizes.
88

ACCESS

90       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
