----- Forwarded message from "Derek B. Noonburg" <derekn(a)foolabs.com> ----- Date: 17 Aug 2005 21:51:23 -0000 Message-ID: <20050817215123.11144.qmail(a)foolabs.com> To: martin(a)oneiros.de From: "Derek B. Noonburg" <derekn(a)foolabs.com> Subject: ANNOUNCE: Xpdf 3.01 - a PDF viewer for X Glyph & Cog, LLC is pleased to announce a new version of Xpdf, the open source Portable Document Format (PDF) viewer for X. The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. Xpdf runs under the X Window System on Unix, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty much any system with a decent C++ compiler. Major changes: * Added the continuous view mode, including the '-cont' switch and the 'continuousView' config file option. * At high zoom levels, don't rasterize the entire page - this avoids problems running out of memory. * Added "search backward" and "match case" options to the find dialog. * Support explicitly masked images and soft masked images. See the `CHANGES' file for a complete list of changes. Source (C++ and C) is available, and it should be fairly easy to compile for UNIX, VMS, OS/2, and Win32. More information, source code, and precompiled binaries are on the xpdf web page and ftp site: http://www.foolabs.com/xpdf/ ftp://ftp.foolabs.com/pub/xpdf/ For information on commercial licensing and consulting, please see the Glyph & Cog web site: http://www.glyphandcog.com/ ----- End forwarded message ----- I'll have a look and might make a new release (1.30.1) together with the latest changes to web2c.

Re: [NTG-pdftex] url links in included pdf documents,
by Thanh Han The 15 Aug '05

15 Aug '05

there was a patch to copy links in embedded pdf's, but it was not integrated to pdf. The patch was not that simple and none of pdftex maintainers (including me) was willing to take care of it. I think a compromise would be allowing certain kind of annotation to be copied, for example URI. But I cannot make any promise, sorry.

Re: [NTG-pdftex] redundant resources
by Thanh Han The 15 Aug '05

15 Aug '05

Hi Hans, does it relate to the ToUnicode object only, or something else as well? I think the ToUnicode object can be generated by pdftex, as pdftex knows the current encoding vector and can find out the corresponding unicode for a given glyph name by looking into the AGL? It would also save some space, as fonts having the same encoding vector (eg 8r.enc) can share a single ToUnicode object. But I am not sure, have to recheck the ToUnicode description. Postponing the object refered by \pdffontattr is not that easy to do, as pdftex does no parsing of the parameter of \pdffontattr (like in case of many other parameters).

redundant resources
by Hans Hagen 15 Aug '05

15 Aug '05

Hi, There are situations where unused resources can end up in a pdf file; think for instance of a font system that sets up tounicode vector inclusion. For practical purposes, one needs to have a font loaded before the document preamble is scanned. If not, it is impossible to deal with certain dimensions. So, it that case, we have something \pdffontattr\font{/ToUnicode ... 0 R} But imagine that we never use that font. If the rest of the document fonts use the same vector, this is no problem, but when we switch to another font encoding, we end up with a non used to unicode vector. Or think of docs with only graphics (or other pdf pages) where no such vector is needed. Because the object reference ... 0 R is not seen, pdftex cannot decide either or not to include the object, so we need to use \immediate\obj which result sin the non wanted entry. A solution is \pdffontvector <obj num> but a more generic solution is \pdffontattr\font{/ToUnicode ... \refobjnum <objnum>} which will tag the object (number) as being used but only when the font desciption object is really flushed (so \refobjnum fullfils a signal function) this means that a (later) \pdfobj{...} will not be flushed when it is not really refered Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

url links in included pdf documents,
by Janko Hauser 09 Aug '05

09 Aug '05

Hello, I have the need to include pdf pages as backgrounds into a latex document. I would like to keep the url-links in these background pdf's. Searching the mailinglists it turns out, that pdftex does strip all links from included pdf's. Has this changed in recent versions? How should one proceed to look for this in the code of pdftex? With regards, __Janko Hauser

compilation under mingw
by Pawel Jackowski 04 Aug '05

Hi there, pdfTeX sources (at least current 1.30.0 and rcandidates) don't compile under mingw environment, although #ifdefs suggest that mingw is supported. src/texk/kpathsea/config.h:85:22 win32lib.h: No such file or directory src/texk/kpathsea/c-ctype.h:26:22 oldnames.h: No such file or directory Has anybody tried? Thanks for any clues. -- Pawe/l Jackowski P.Jackowski(a)gust.org.pl

Re: [NTG-pdftex] compilation under mingw
by Thanh Han The 02 Aug '05

02 Aug '05

I spent a lot of time to compile pdftex with mingw in the past, but in the end I think that it's not worthwhile for the trouble so I gave it up. Using the djgpp cross-compiler is much easier ad allows me to use the same sources for compiling binaries for linux and dos/windows.
