Description Tim Waugh 2010-11-19 05:59:18 UTC

CUPS (www.cups.org) uses a wrapper around the pdftops utility from poppler in order to handle PDF documents.  Previously, a private fork of xpdf had been used, with some additions to make it behave more usefully as a CUPS filter.

It would be really useful if pdftops could be enhanced in the following ways:

* pdftops could be instructed to always produce portrait PostScript documents, rotating the input pages as needed

* correct BoundingBox DSC comments for each page in the output

* an additional comment 'cupsRotation: 0' added indicating that no further rotation of the document is required

I understand cups already does that in their copy, so where are the patches?

Comment 2 Tim Waugh 2010-11-22 06:31:15 UTC

CUPS used to have a private fork of xpdf which had been modified in several ways so that it would unconditionally act as a CUPS filter.

I'm not sure of the best approach for getting the needed changes upstream to make pdftops better-behaved as a CUPS filter.  Obviously, unconditional changes will not be any good, so a command line option of some sort is probably the way to go.

Do you think that a single option such as "--cupsfilter" would be acceptable and make sense?

Comment 3 Albert Astals Cid 2010-11-22 11:33:46 UTC

I'd sincerely prefer more fine grained options like
--alwaysPortrait
--addCupsRotation
--fooBar

Than just a huge "--cupsMagic".
