hvectext - construct Geomview VECT text object from Hershey fonts


hvectext [-w totallength] [-s textheight] [-plane xy|xz|yz] [-at X Y Z]
[-align n|s|e|w|ne|nw|se|sw|c] [-hershey fontfile.gsf] [--] text string ...


Hvectext generates a Geomview/OOGL vector-text object, of given height or total length
(default -s .25). It aligns the given 3-D point (default -at 0 0 0) with the given corner
of the text (default -align c). Alignment specs are like geographic directions; -align sw
puts the ``at'' point at the ``southwest'' corner of the text, so that its lower left
corner is at that coordinate.

The corresponding VECT object is written to standard output. If no non-blank text
characters are given, hvectext produces a null geom object ("{ }") as output.

The special option -- marks the end of options; it's useful in case the text itself begins
with a hyphen.

Hvectext accepts Ghostscript Hershey fonts; the built-in default is Hershey-Plain-Simplex
a.k.a. hrpl_s.gsf. Others of interest: hrsy_r.gsf (Symbol), hrpl_t.gsf (Triplex). For a
complete list, see all the Ghostscript font files of nontrivial size whose names begin
with "hr".

Although there's no way to switch fonts within the string, the first line of output from
hvectext is an OOGL comment resembling:
# Continue with: -align sw -plane xy -s 0.25 -at 1.24378 0 0
giving options for hvectext to continue the string where it left off.


GS_FONTPATH, if present, is a colon-separated list of directories in which Hershey font
files are sought.
