6 grodvi \- convert groff output to TeX dvi format
22 that produces \*(tx dvi format.
23 Normally it should be run by

28 .BR @MACRODIR@/tmac.dvi ;
29 if the input is being preprocessed with
32 .BR @FONTDIR@/devdvi/eqnchar .
34 The dvi file generated by
36 can be printed by any correctly-written dvi driver.
37 The troff drawing primitives are implemented
38 using the tpic version 2 specials.
39 If the driver does not support these, the
41 commands will not produce any output.
43 There is an additional drawing command available:
46 Draw a rule (solid black rectangle), with one corner
47 at the current position, and the diagonally opposite corner
48 at the current position
50 Afterwards the current position will be at the opposite corner. This
51 produces a rule in the dvi file and so can be printed even with a
52 driver that does not support the tpic specials unlike the other

93 in the corresponding tfm file;
94 all characters in the tfm file can be accessed this way.
98 Do not use tpic specials to implement drawing commands.

100 Other drawing commands will be ignored.

138 vertical and horizontal lines can sometimes protrude by one pixel.
139 This is a consequence of the way \*(tx requires that the heights
140 and widths of rules be rounded.
