Patch CreationDate
by Heiko Oberdiek 11 Aug '03

11 Aug '03

Hello, Patch CreationDate If /CreationDate is not given by \pdfinfo, then a default is used by computing the string by the current setting of \year, \month, and \time. Problem A: The time zone is not set. See the discussion in de.comp.text.tex, "[pdftex] Zeitzone von CreationDate" Valentin Schwamberger observed that his AR/Windows shows then the time as GMT. Problem B: It is easy to fool pdfTeX: * Setting \year to a number less or greater than 4 digits. * Setting \year, \month, \date, \time to invalid numbers, eg.: \month=13 The result are invalid dates. The following patch tries to solve these problems: * Time zone detection by glibc's strftime("%z"). * The current time is used, not \year, \month, ... Patch files based on 2003/07/30 v1.11a: utils.c.diff for TeX/texk/web2c/pdftexdir/utils.c pdftex.ch.diff for TeX/texk/web2c/pdftexdir/pdftex.ch pdftex.defines.diff for TeX/texk/web2c/pdftexdir/pdftex.defines Yours sincerely Heiko <oberdiek(a)uni-freiburg.de> --

pdftex documentation

Since we have so many changes in pdftex, is there any chance having pdf documentation updated. There are still some documents in pdf format in texmf/doc/pdftex/ , but... from Nov, 2 2001 Anyway I'd suggest adding texmf/doc/pdftex/NEWS Ps. I'm bombarded by mails concerning, e.g., adjusting spaces, fontexpand, efcode, etc., but cannot help :-( Thanks, -- Staszek Wawrykiewicz StaW(a)gust.org.pl

Bug: <hex> string to () string

Hello, I wanted to include pdf slides from: http://ais.informatik.uni-freiburg.de/lehre/ss03/ki/slides/01-intro.pdf by pdfTeX, but the colors in some of the images are terrible wrong.

still beta?
by Martin Schroeder 16 Jul '03

16 Jul '03

from the REAME: It is still under beta development and all features are liable to change. Despite its beta state, pdfTeX produces excellent PDF code. Is pdfTeX still in beta state? Methinks it has matured enough. :-) Best regards Martin -- Martin Schröder, MS(a)ArtCom-GmbH.DE ArtCom GmbH, Lise-Meitner-Str 5, 28359 Bremen, Germany Voice +49 421 20419-44 / Fax +49 421 20419-10

In that case, one can use that version number since the moment that those fixes are in the new distribution sync with the ifeof18 extension.
