matplotlib-devel Mailing List for matplotlib

Hello,
The current matplotlib installers for Windows are built with Microsoft
Visual Studio 2003/2008 compilers. It is relatively easy once you have
all the dependencies and it gives you working binaries for Python 2.4,
2.5, 2.6, and 2.6 64-bit.
I have found the instructions at
<http://matplotlib.sourceforge.net/users/installing.html> and
<http://docs.python.org/install/> sufficient for building matplotlib
from sources. My setup.cfg is attached.
Matplotlib, when compiled with mingw, had some problems saving png
images
<http://www.mail-archive.com/mat...@li.../msg11791.html>.
Can you save to pdf?
I have not tried libpng-1.2.40, it is three weeks old, but version
1.2.42 works when PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN,
PNG_ALLOCATED, PNG_DEPSTRUCT, PNG_STDIO_SUPPORTED, and
PNG_SEQUENTIAL_READ_SUPPORTED are defined.
I can not reproduce the GTK problems with the latest official matplotlib
0.99.1, pyGTK 2.12.1-3, and GTK 2.16.6 binaries. Are you using the GTK
or GTKAgg backend?
