/** charset5.h HP-GL character set 5, Special Symbols
** MK February 1999
**/
/**
** This file defines character set 5 by elementary
** "draw" & "move" commands. The format is a very compact one from
** the old days where every byte was still appreciated.
**
** A font or character set is an array of strings. Each character
** corresponds to one of these strings, which is addressed by its ASCII code.
**
** A character is a (NULL-terminated) string of bytes. Each byte
** codes for a draw or move action according to the code below:
**
** Bit: 7 6 5 4 3 2 1 0
** p x x x y y y y
**
** p: Plot flag. If set, "draw to" new point, else "move to" it.
** xxx: 3-bit unsigned integer (0...7). X coordinate of new point.
** yyyy: 4-bit unsigned integer (0..15). Y coordinate of new point.
**
** The baseline is y = 4 instead of y = 0, so characters with parts
** below it can be drawn properly without a need for sign bits.
** Function "code_to_ucoord()" transforms these coordinates into
** actual user coordinates.
**
** Example: code for character 'L': "\032\224\324" translates to:
** moveto(1,10); drawto(1,4); drawto(5,4);
**
** From the example you can conclude that the font below essentially is
** defined on a 5x7 grid:
**
** 0 1 2 3 4 5 6 7
** 15 . . . . . . . . . : unused
** 14 . . . . . . . . * : always used
** 13 . . . . . . . . o : sometimes used
** 12 . . . . . . . .
** 11 . . . . . . . .
** 10 o * * * * * . .
** 9 o * * * * * . .
** 8 o * * * * * . .
** 7 o * * * * * . .
** 6 o * * * * * . .
** 5 o * * * * * . .
** 4 o * * * * * . .
** 3 o o o o o o . .
** 2 o o o o o o . .
** 1 o o o o o o . .
** 0 o o o o o o . .
**/
/**
** The following array of strings contains the basic character set (set 0).
**
** NOTE: A nice way to add a new charset would be, e. g., to introduce a
** ``charset1[]'' as the "alternate" charset and implement the HP-GL
** commands needed for switching from one to the other.
**/
char *charset5[128] =
{
/* 0x00 ... 0x1f */
/**
** Some control codes are valid in HPGL. These are handled elsewhere
** in a font-independent manner, so following codes are dummies:
**/
"","","","", "","","","", "","","","", "","","","",
"","","","", "","","","", "","","","", "","","","",
/**
** Unfortunately, some compilers do not process \xNN properly,
** so I changed all hex codes (\xNN) into octal codes (\NNN),
** thereby losing readability but gaining portability.
