Using the option "-P-l", as Clarke suggests, is the simplest (and very
straightforward) way to get a document printed entirely in landscape
format (though of course you need to be careful about the page-size
metrics, depending on the formatting).
It is, however, possible to rotate parts of a page (keeping the pager
as a whole unrotated) if you are using PostScript output. For this
you need to define some PostScript code to be inserted using
"\X'ps: exec ... ". Here is a toy example (though using non-toy
definitions ... ):
.ds rotate "\X'ps: exec gsave currentpoint 2 copy translate \
\\$1 rotate neg exch neg exch translate'
.ds restore "\X'ps: exec grestore'
\Z'\D'p 1i 0i 0i 1i -1i 0 0 -1i''\
\*[rotate -45]\
\Z'\D'p 1i 0i 0i 1i -1i 0 0 -1i''\
\Z'\0\0\0Hello'\
\*[restore]\
\0\0\0Hello
The above defines two PostScript command strings \*[rotate]
and \*[restore]. \*[rotate] takes an argument which is the angle
of clockwise rotation about the current point in degrees clockwise,
so that "*[rotate -45]" rotates 45 degrees anticlockwise.
Then it draws a 1-inch-square box atarting at its top left-hand
corner, returning to the starting point; then it sets up a 45-degree
anticlockwise rotation (about the starting-point) and draws it again,
this time with "Hello" on its upper edge; then it invokes \*[restore]
which restores things to their pre-\*[rotate] state and again puts
"Hello" on the top edge of the first box (just to prove that the
restoration has worked).
Best wishes to all,
Ted.
