<_param name="aboutpage" type="description" xml:space="preserve">This tool renders a line of text using specialized
|
||||
"stroke" or "engraving" fonts designed for plotters.
|
||||
|
||||
Whereas regular "outline" fonts (e.g., TrueType) work
|
||||
by filling in the region inside an invisible outline,
|
||||
engraving fonts are composed only of individual lines
|
||||
or strokes; much like human handwriting.
|
||||
|
||||
Engraving fonts are used for creating text paths that
|
||||
computer controlled drawing and cutting machines (from
|
||||
pen plotters to CNC routers) can efficiently follow.

The classic fonts included -- those without the "EMS"

prefix -- are derived from work by Dr. A. V. Hershey,

distributed by the US National Bureau of Standards

(now NIST) in NBS SP-424 1976-04, "A contribution to

computer typesetting techniques: Tables of Coordinates

for Hershey's Repertory of Occidental Type Fonts and
|

Graphic Symbols."
