CTAN package update: pdftex 1.40.0
by CTAN Announcements 01 Jan '07

01 Jan '07

The package below has been updated at tug.ctan.org and should soon be at your favorite mirror. Thank you, Jim Hefferon Saint Michael's College ......................................................................... The following information was provided by our fellow contributor: Name of contribution: pdftex 1.40.0 Author's name: Martin Schröder Location on CTAN: /systems/pdftex Summary description: A new version of pdftex License type: gpl Announcement text: ---------------------------------------------------------------------- The pdfTeX team is happy to announce the release of a new stable version: =========================================================================== pdfTeX 1.40.0 =========================================================================== This is the announcement of pdfTeX 1.40.0, an extended version of TeX that can create PDF directly from TeX source files and enhance the result of TeX typesetting with the help of PDF. =========================================================================== Main changes of pdfTeX 1.40.0 =========================================================================== - pdfetex (as a separate binary/program) is gone; all extensions are now in pdftex. The make files still know about the target pdfetex, but it's just a copy of pdftex - The sources of TeX, eTeX and pdfTeX have been merged into one file pdftex.web and one change file pdftex.ch. The sources of TeX and eTeX distributed are just there for reference - New features: - pdfTeX can now generate PDF 1.5 object streams, which leads to smaller PDFs. This is controlled by setting pdfobjcompresslevel to a value >0 (3 compress everything, 2 don't compress /Info, 1 also don't compress embedded PDFs) and works only with PDF >=1.5 - pdfTeX now supports another image file format: JBIG2 files (.jbig2) - the memory allocated for objects and destination names now grows dynamically - pdfTeX now generates smaller PDFs since for char positioning the width of chars (/Widths) is stored with more precision and so the chars must rarely be positioned separately - the PK resolution is now taken from the pk_dpi parameter in texmf.cnf if it has not been set in the format file or by the user - pdfTeX now removes the generated pdf in case of a fatal error - pdfTeX now sets /ModDate and /Trapped in the InfoDict by default (the values can be overridden with pdfinfo) - the format of warnings and errors issued by pdfTeX has been changed and unified - the output of -version has been extended and now includes information about the libraries actually used, which can be handy when using shared libraries - rules and their positioning on the page are now inside a qQ group - New primitives: - pdfTeX can now handle colourstacks. - pdfcolorstackinit A stack is initialized by pdfcolorstackinit. It expands to the number of the new stack. The common case, the traditinal color stack is already initialized as first stack: pdfcolorstackinit page direct {0 g 0 G} The keyword page means that this stack is page based. At the start of the new page, the current stack value is automatically set. - pdfcolorstack pdfcolorstack <stack number> push {<new color>} pushes the current value on the stack and sets the <new color>. pdfcolorstack <stack number> pop pops and sets the current stack value. pdfcolorstack <stack number> current sets the current stack value without changing the stack. This is useful for stacks that are initialized without keyword page. Thus the page start setting can be set manually. pdfcolorstack <stack number> set {<new color>} The current value is set to <new color>. - Transformation matrices can now be manipulated more cleanly: Currently matrix changes are done and hidden inside pdfliteral nodes; pdfTeX doesn't parse its contents and does not know the new settings of the transform matrix. Thus the new primitives to save pdfTeX from parsing pdfliteral contents and to notify pdfTeX about matrix changes to use them in calculating link and anchor positions. - pdfsetmatrix{<a> <b> <c> <d>} is the equivalent to pdfliteral{<a> <b> <c> <d> 0 0 cm} - pdfsave is the equivalent to pdfliteral{q} - pdfrestore is the equivalent to pdfliteral{Q} - pdfprimitiveTeX-primitive executes the original TeX-primitive even if the command has been redefined since. E.g. let elaxundefinedpdfprimitive elax expands to elax. ifpdfprimitiveTeX-primitive is true if TeX-primitive has its original meaning - ifpdfabsnum and ifpdfabsdim are like ifnum and ifdim, but don't care about negative numbers - shell escape: if the first character of a filename for openin, openout input is a pipe symbol (|), the filename is assumed to be a request for a pipe to a command line that is given in the rest of the filename - draftmode: With pdfdraftmode=1 or the commandline switch -draftmode pdfTeX doesn't write the output pdf and doesn't actually read any images, thus speeding up compilations when you know you need an extra run but don't care about the output, e.g. just to get the BibTeX references right - pdfpxdimen (introduced in 1.30) is now a real dimension parameter. It allows one base dimensions on pixels. 1px defaults to 1bp (or 72dpi), but can be changed with the pdfpxdimen primitive: pdfpxdimen=1in % 1 dpi dividepdfpxdimen by 96 % 96 dpi hsize=1200px Now hsize is (1in/96)*1200 - pdflastlink returns the object number of the last pdfstartlink - pdfsavepos now works in DVI mode - Fonts: - support for subfonts: This creates all needed map entries for subfonts automatically and handles Unicode mappings - ToUnicode entries for Type1 fonts (patch 580) - HZ: - added patch 462: HZ font expansion in autoexpand mode now produces smaller pdf files, as it works by modififying the text matrix for single fonts instead of embedding many expanded font versions. Therefore HZ now can be used also for TrueType fonts and even for non-embedded fonts (e.g. Times-Roman) - Bugfixes: - the PDF statistics in the log are now correct - added JFIF detection patch to writejpg.c (bug 548) - bugfix: invalid pdf created if font name contains space (509) - bugfix: truetype OS/2 v3 fonts (594) - bugfix: Type1C (CFF) fonts of embedded pdfs didn't get replaced For complete release notes see http://www.pdftex.org/NEWS =========================================================================== Legal notice / license =========================================================================== pdfTeX is copyright (c) 1996-2007 Han The Thanh, <thanh(a)pdftex.org> pdfTeX is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

A new package has been put on tug.ctan.org and should soon be at your favorite mirror. Happy new year, Jim Hefferon Saint Michael's College ............................................................................... The following information was provided by our fellow contributor: Name of contribution: refreshpdf Author's name: Claus Gerhardt Location on CTAN: /support/refreshpdf Summary description: Refreshpdf refreshes a pdf file opened in Acrobat (Mac OS X) License type: lppl Announcement text: ---------------------------------------------------------------------- Refreshpdf is an Applescript that takes the path of a pdf file as argument and then opens the file in Acrobat. If the file is already open in Acrobat, then Acrobat is told to close and reopen the file and to go to the same page that was displayed in the closed file. The Applescript can also be called from the command line by a shell script refreshpdf. Refreshpdf only works on MacOS X. ---------------------------------------------------------------------- This package is located at http://tug.ctan.org/tex-archive/support/refreshpdf .
