postreverse - reverse the page order in a PostScript file


postreverse [ -o list ] [ -r ] [ file ] /usr/lib/lp/postscript/postreverse


The postreverse filter reverses the page order in files that conform to Adobe's Version 1.0 or Version 2.0 file structur- ing conventions, and writes the results on the standard out- put. Only one input file is allowed and if no file is specified, the standard input is read. The postreverse filter can handle a limited class of files that violate page independence, provided all global defini- tions are bracketed by %%BeginGlobal and %%EndGlobal com- ments. In addition, files that mark the end of each page with %%EndPage: label ordinal comments will also reverse properly, provided the prologue and trailer sections can be located. If postreverse fails to find an %%EndProlog or %%EndSetup comment, the entire file is copied, unmodified, to the standard output. Because global definitions are extracted from individual pages and put in the prologue, the output file can be minimally conforming, even if the input file was not.


-o list Select pages whose numbers are given in the comma- separated list. The list contains single numbers N and ranges N1 - N2. A missing N1 means the lowest numbered page, a missing N2 means the highest. The page range is an expression of logical pages rather than physical sheets of paper. For example, if you are printing two logical pages to a sheet, and you specified a range of 4, then two sheets of paper would print, containing four page layouts. If you specified a page range of 3-4, when requesting two logical pages to a sheet; then only page 3 and page 4 layouts would print, and they would appear on one physical sheet of paper. -r Do not reverse the pages in file.

No attempt has been made to deal with redefinitions of glo- bal variables or procedures. If standard input is used, the input file will be read three times before being reversed. SunOS 5.8 Last change: 9 Sep 1996 2
