27 | /** |
28 | ** This file defines character set 5 by elementary |
29 | ** "draw" & "move" commands. The format is a very compact one from |
30 | ** the old days where every byte was still appreciated. |
31 | ** |
32 | ** A font or character set is an array of strings. Each character |
33 | ** corresponds to one of these strings, which is addressed by its ASCII code. |
34 | ** |
35 | ** A character is a (NULL-terminated) string of bytes. Each byte |
36 | ** codes for a draw or move action according to the code below: |
37 | ** |
38 | ** Bit: 7 6 5 4 3 2 1 0 |
39 | ** p x x x y y y y |
40 | ** |
41 | ** p: Plot flag. If set, "draw to" new point, else "move to" it. |
42 | ** xxx: 3-bit unsigned integer (0...7). X coordinate of new point. |
43 | ** yyyy: 4-bit unsigned integer (0..15). Y coordinate of new point. |
44 | ** |
45 | ** The baseline is y = 4 instead of y = 0, so characters with parts |
46 | ** below it can be drawn properly without a need for sign bits. |
47 | ** Function "code_to_ucoord()" transforms these coordinates into |
48 | ** actual user coordinates. |
49 | ** |
50 | ** Example: code for character 'L': "\032\224\324" translates to: |
51 | ** moveto(1,10); drawto(1,4); drawto(5,4); |
52 | ** |
53 | ** From the example you can conclude that the font below essentially is |
54 | ** defined on a 5x7 grid: |
55 | ** |
56 | ** 0 1 2 3 4 5 6 7 |
57 | ** 15 . . . . . . . . . : unused |
58 | ** 14 . . . . . . . . * : always used |
59 | ** 13 . . . . . . . . o : sometimes used |
60 | ** 12 . . . . . . . . |
61 | ** 11 . . . . . . . . |
62 | ** 10 o * * * * * . . |
63 | ** 9 o * * * * * . . |
64 | ** 8 o * * * * * . . |
65 | ** 7 o * * * * * . . |
66 | ** 6 o * * * * * . . |
67 | ** 5 o * * * * * . . |
68 | ** 4 o * * * * * . . |
69 | ** 3 o o o o o o . . |
70 | ** 2 o o o o o o . . |
71 | ** 1 o o o o o o . . |
72 | ** 0 o o o o o o . . |

79 | ** NOTE: A nice way to add a new charset would be, e. g., to introduce a |
