4 % This file can be prepended to most PostScript pages to force
5 % rotation to "landscape" mode.
7 % There are (at least) four possible ways to reasonably position a
8 % page after rotation. Any of the four old corners (llx,lly e.g.)
9 % can be moved to match the corresonding new corner.
10 % By uncommmenting the appropriate line below (i.e., remove the
11 % leading '%'), any such positioning can be chosen for positive or
12 % negative rotation. The comments at the end of each "rotate" line
13 % indicate the ORIGINAL corner to be aligned. For example, as given
14 % below, the lower left hand corner is aligned. When viewed, this
15 % corner will have moved to the urx,lly corner.
