!!DESCRIPTION |
| |
|
25 |
|
| |
|
26 |
|
| |
|
27 |
__grodvi__ is a driver for __groff__ that produces TEX |
| |
|
28 |
dvi format. Normally it should be run by __groff -Tdvi__. |
| |
|
29 |
This will run __troff -Tdvi__; it will also input the |
| |
|
30 |
macros __/usr/share/groff/1.17.2/tmac/dvi.tmac__; if the |
| |
|
31 |
input is being preprocessed with __eqn__ it will also |
| |
|
32 |
input |
| |
|
33 |
__/usr/share/groff/1.17.2/font/devdvi/eqnchar__. |
| |
|
34 |
|
| |
|
35 |
|
| |
|
36 |
The dvi file generated by __grodvi__ can be printed by |
| |
|
37 |
any correctly-written dvi driver. The troff drawing |
| |
|
38 |
primitives are implemented using the tpic version 2 |
| |
|
39 |
specials. If the driver does not support these, the __D__ |
| |
|
40 |
commands will not produce any output. |
| |
|
41 |
|
| |
|
42 |
|
| |
|
43 |
There is an additional drawing command |
| |
|
44 |
available: |
| |
|
45 |
|
| |
|
46 |
|
| |
|
47 |
__D'R__ ''dh dv''__'__ |
| |
|
48 |
|
| |
|
49 |
|
| |
|
50 |
Draw a rule (solid black rectangle), with one corner at the |
| |
|
51 |
current position, and the diagonally opposite corner at the |
| |
|
52 |
current position +(''dh'',''dv''). Afterwards the |
| |
|
53 |
current position will be at the opposite corner. This |
| |
|
54 |
produces a rule in the dvi file and so can be printed even |
| |
|
55 |
with a driver that does not support the tpic specials unlike |
| |
|
56 |
the other __D__ commands. |
| |
|
57 |
|
| |
|
58 |
|
| |
|
59 |
The groff command __X'__''anything''__'__ is |
| |
|
60 |
translated into the same command in the dvi file as would be |
| |
|
61 |
produced by __special{__''anything''__}__ in TEX; |
| |
|
62 |
''anything may not contain a newline.'' |
| |
|
63 |
|
| |
|
64 |
|
| |
|
65 |
Font files for __grodvi__ can be created from tfm files |
| |
|
66 |
using tfmtodit(1). The font description file should |
| |
|
67 |
contain the following additional commands: |
| |
|
68 |
|
| |
|
69 |
|
| |
|
70 |
__internalname__ ''name'' |
| |
|
71 |
|
| |
|
72 |
|
| |
|
73 |
The name of the tfm file (without the __.tfm__ extension) |
| |
|
74 |
is ''name''. |
| |
|
75 |
|
| |
|
76 |
|
| |
|
77 |
__checksum__ ''n'' |
| |
|
78 |
|
| |
|
79 |
|
| |
|
80 |
The checksum in the tfm file is ''n''. |
| |
|
81 |
|
| |
|
82 |
|
| |
|
83 |
__designsize__ ''n'' |
| |
|
84 |
|
| |
|
85 |
|
| |
|
86 |
The designsize in the tfm file is ''n''. |
| |
|
87 |
|
| |
|
88 |
|
| |
|
89 |
These are automatically generated by |
| |
|
90 |
__tfmtodit.__ |
| |
|
91 |
|
| |
|
92 |
|
| |
|
93 |
In __troff__ the __N__ escape sequence can be used to |
| |
|
94 |
access characters by their position in the corresponding tfm |
| |
|
95 |
file; all characters in the tfm file can be accessed this |
| |
|
96 |
way. |

Do not use tpic specials to implement drawing commands. |

Horizontal and vertical lines will be implemented by rules. |

Other drawing commands will be ignored. |

!!BUGS |
| |
|
146 |
|
| |
|
147 |
|
| |
|
148 |
Dvi files produced by __grodvi__ use a different |
| |
|
149 |
resolution (57816 units per inch) to those produced by TEX. |
| |
|
150 |
Incorrectly written drivers which assume the resolution used |
| |
|
151 |
by TEX, rather than using the resolution specified in the |
| |
|
152 |
dvi file will not work with __grodvi__. |
| |
|
153 |
|
| |
|
154 |
|
| |
|
155 |
When using the __-d__ option with boxed tables, vertical |
| |
|
156 |
and horizontal lines can sometimes protrude by one pixel. |
| |
|
157 |
This is a consequence of the way TEX requires that the |
| |
|
158 |
heights and widths of rules be rounded. |
