USE RESTRICTION: This distribution of the Hershey Fonts may be used by anyone for any purpose, commercial or otherwise, providing that: 1. The following acknowledgements must be distributed with the font data: - The Hershey Fonts were originally created by Dr. A. V. Hershey while working at the U. S. National Bureau of Standards. - The format of the Font data in this distribution was originally created by James Hurt Cognition, Inc. 900 Technology Park Drive Billerica, MA 01821 (mit-eddie!ci-dandelion!hurt) 2. The font data in this distribution may be converted into any other format *EXCEPT* the format distributed by the U.S. NTIS (which organization holds the rights to the distribution and use of the font data in that particular format). Not that anybody would really *want* to use their format... each point is described in eight bytes as "xxx yyy:", where xxx and yyy are the coordinate values as ASCII numbers.
The format of the files is described as follows:
The structure is bascially as follows: each character consists of a number 1->4000 (not all used) in column 0:4, the number of vertices in columns 5:7, the left hand position in column 8, the right hand position in column 9, and finally the vertices in single character pairs. All coordinates are given relative to the ascii value of 'R'. If the coordinate value is " R" that indicates a pen up operation.
As an example consider the 8th symbol8 9MWOMOV RUMUV ROQUQIt has 9 coordinate pairs (this includes the left and right position).
The left position is 'M' - 'R' = -5
The right position is 'W' - 'R' = 5
The first coordinate is "OM" = (-3,-5)
The second coordinate is "OV" = (-3,4)
Raise the pen " R"
Move to "UM" = (3,-5)
Draw to "UV" = (3,4)
Raise the pen " R"
Move to "OQ" = (-3,-1)
Draw to "UQ" = (3,-1)
Drawing this out on a piece of paper will reveal it represents an 'H'.
