% This file can be prepended to most PostScript pages to force
|
|
% rotation to "landscape" mode.

|
% There are (at least) four possible ways to reasonably position a
|
|
% page after rotation. Any of the four old corners (llx,lly e.g.)
|
|
% can be moved to match the corresonding new corner.
|
|
% By uncommmenting the appropriate line below (i.e., remove the
|
|
% leading '%'), any such positioning can be chosen for positive or
|
|
% negative rotation. The comments at the end of each "rotate" line
|
|
% indicate the ORIGINAL corner to be aligned. For example, as given
|
|
% below, the lower left hand corner is aligned. When viewed, this
|
|
% corner will have moved to the urx,lly corner.
