This is also tracked by Debian at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=421464 A much simpler testcase is attached. The manual is interesting in this case: "If the font flags are not given, pdfTEX treats it as being 4, a symbolic font. If you do not know the correct value, it is best not to specify it at all, as specifying a bad value of font flags may cause troubles in viewers." The usual map files have no font flag entry for Helvetica. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-05-25 19:48 Message: Logged In: YES user_id=421 A fix for this will be included in the next release (1.40.4/1.50.0). ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=794&group_id=106

Pdflatex Bugs with figures
by Heba Soliman 15 May '07

15 May '07

When I use pdflatex with an article that has no figures, it is more than perfect. But when the article has figures there are problems with the resolution and the testing with PDF/A. Please help me I don't know how to fix the resolution of the figures using pdflatex, also how to make it compatible with PDF/A in Acrobat 7.0, it gives me an error "Unknown error (unknown exception)".

It is not necessary to explain it. Now, there are some tools to do it, but they are far of being good enough. For instance, pdfsync makes some work, but it has a lot of problems. Of instance, the output is different with or without pdfsync. I have read in TUGboat that, perhaps in the near future, pdfsync can be integrated en pdftex itself and improved. I request to do it as soon as possible. Yours sincerely, Juan L.

[ pdftex-Patches-474 ] Use dynamically linked poppler library instead of xpdf code

Patches item #474, was opened at 2006-01-30 17:53 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=474&group_id=106 Category: PDF inclusion Group: v1.30.0 Status: Open Resolution: Postponed >Priority: 6 Submitted By: Frank Küster (frank) Assigned to: Martin Schröder (oneiros) Summary: Use dynamically linked poppler library instead of xpdf code Initial Comment: This has already been applied and tested in Debian and Ubuntu, but we suggest to apply it upstream. There are a few things to do, however, as Martin already pointed out to me in a private mail. I paraphrase the main points: - the pdftex distribution should not ship libpoppler. Instead it should be possible to switch from xpdf to libpoppler using autoconf magic, if libpoppler headers are installed. This needs some coding work - We need a common API for xpdf and poppler. This is the tricky part, because the very reason for poppler's existence is that the xpdf developer, Derek Noonburg, refuses any patches that would lead to a shared library. As Martin said, "for the beginning, a header file with a couple of #ifdef'ed definitions should be enough". I'm going to subscribe to the pdftex devel list soon, but am not yet subscribed currently. ---------------------------------------------------------------------- >Comment By: Martin Schröder (oneiros) Date: 2007-05-08 18:54 Message: Logged In: YES user_id=421 Just an update: SUSE has also started switching to poppler. My idea is to first add an abstraction layer for xpdf/poppler/... and then add the autofoo stuff. ---------------------------------------------------------------------- Comment By: Frank Küster (frank) Date: 2006-08-14 21:20 Message: Logged In: YES user_id=3360 Hi Martin, this is clearly post-1.40, I agree. I have not worked on any autofoo stuff, and I won't be able to do that soon (instead, I try to integrate pdftex-1.40 into teTeX 3.0 which proved to be non-trivial). Regards, Frank ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-08-13 22:02 Message: Logged In: YES user_id=421 Frank, have you done any further work on this? I just had a first look at integrating poppler and see a very different use of configure... :-{ Also your diff only patches the sources, but not the autofoo-stuff. What I want is: - a distribution of poppler in src/libs, which can be used instead of xpdf - a way to switch bewteen xpdf and poppler via configure - for poppler to be able to switch between static and dynamic via configure - and finally, a header file abstracting poppler/xpdf would be nice, but is not really needed, as poppler/xpdf are only used by two source files. Best Martin ---------------------------------------------------------------------- Comment By: Frank Küster (frank) Date: 2006-02-13 08:58 Message: Logged In: YES user_id=3360 I agree that this is something to think over and check very well, so better not push it into 1.40. But I'd appreciate if someone could answer my mail to ntg-pdftex regarding the autoconf setup in pdftex, or if you could tell me whom to ask specifically if nobody among the active developers knows about it. See you in Berlin, Frank ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-02-13 01:50 Message: Logged In: YES user_id=421 I've attached the patch by Frank from http://www.ntg.nl/pipermail/ntg-pdftex/2006-February/001993.html ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-02-13 01:46 Message: Logged In: YES user_id=421 This is too late for 1.40, so I'll postpone it. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=474&group_id=106
