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.
