ANN: Pyrex 0.9.8.1
by greg 17 May '08

17 May '08

Pyrex 0.9.8.1 is now available: http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/ Base classes no longer need to be specified in a forward declaration of an extension type, or in the implementation part of an extension type defined in a .pxd file. Also, I've come up with an even better way of handling circular cimports involving structs, unions and extension types. You can now say things like from spam import struct Foo, union Blarg, class Ham This simultaneously imports the name and forward-declares it in the other module. What is Pyrex? -------------- Pyrex is a language for writing Python extension modules. It lets you freely mix operations on Python and C data, with all Python reference counting and error checking handled automatically.

ANN: pdfposter 0.4
by Hartmut Goebel 16 May '08

16 May '08

I'm pleased to announce pdfposter 0.4, a tool to scale and tile PDF images/pages to print on multiple pages. http://pdfposter.origo.ethz.ch/download/ Download --------------- :Quick Installation: easy_install -U pdfposter :Tarballs: http://pdfposter.origo.ethz.ch/download/ What is pdfposter? -------------------- Scale and tile PDF images/pages to print on multiple pages. ``Pdfposter`` can be used to create a large poster by building it from multple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size. This is much like ``poster`` does for Postscript files, but working with PDF. Since sometimes poster does not like your files converted from PDF. :-) Indeed ``pdfposter`` was inspired by ``poster``. For more information please refere to the manpage or visit the `project homepage <http://pdfposter.origo.ethz.ch/>`_. :Author: Hartmut Goebel <h.goebel(a)goebel-consult.de> :Copyright: GNU Public Licence v3 (GPLv3) :Homepage: http://pdfposter.origo.ethz.ch/ -- Schönen Gruß - Regards Hartmut Goebel Goebel Consult Spezialist für IT-Sicherheit in komplexen Umgebungen http://www.goebel-consult.de
