matplotlib can be used to generate .ps, .pdf and .svg files (all
vectorial formats) without resorting to Antigrain
Antigrain is used only in rasterizing, due to its better capabilities
in the field of antialiasing, when you use matplotlib with an
interactive backend; of course, if you're truly dispising Antigrain
and are happy with a coarser display you can select interactive
backends that DO NOT use Antigrain
that's for the Antigrain wrapper
otoh, if the OP intended a plotting library that does not use binary
modules at all (then his reference to Antigrain was mostly fogging),
then matplotlib is not for him

Hi John,
I had the same problem using Btl. Blt generate postscript file and I
needed several others formats, then I did something like this:
cmd = [gspath,
'-sDEVICE=%s'%device,
'-sOutputFile=%s'%onormfile,
'-dNOPAUSE -q -dBATCH',
'%s'%inormfile,
]
gscmd = ' '.join(cmd)
try:
retcode = call(gscmd, shell=True)
if retcode > 0:
log.error("'ghostscript' return whit error code '%d'"%retcode)
except OSError, e:
log.error("Error trying execute 'ghostscript'")
...
remarks:
- gspath is the absolute path to the ghostscript executable
- device can be 'pdfwrite', 'jpeg', 'bmp256', 'png256'
- onormfile is the output filename normalized to the OS
- inormfile is the postscript filename normalized to the OS
- call is the function of subprocess module
warning: ghostscript do not accept spaces in the filenames, so be
carefull if you is working in win32, even enclosing between " ".
PS:
For those people that sugest use Blt. I use Blt a lot in linux and
win32 but it is not port (yet) to TK8.5 so, it do not works with
py2.6, and is really painfull to build in win32.
Beside that, in order to use Blt, you need an instance of Tk running,
ergo a XWindows running, an some times it is not the case for linux
servers. In that cases I am using Mathplotlib, but a pure python
solution will be GREAT!

Looking for a pure Python chart drawing module
I'm looking for something that can draw simple bar and pie charts in Python. I'm trying to find a Python package, not a wrapper for some C library, as this has to run on both Windows and Linux and version clashes are a problem. Here's the list from the Python wiki at "http://wiki.python.org/moin/NumericAndScientific/Plotting";. Almost all the options are really wrappers for some other package in C/C++. * Matplotlib -- wrapper for Antigrain, written in C/C++ * Veusz -- requires PyQt from http://www.riverbankcomputing.co.uk/pyqt, which is in C/C++ * Chaco -- requires binaries for Enthought Tool Suite * ScientificPython - uses mix of C, C++, and FORTRAN. * Gnuplot module -- wrapper for GNUPLOT * plot_wrap - wrapper for GNU plotutils * BLT - "tcltk.com" link goes to a domain squatter site. * PyQT - wrapper for Qwt C++ library * DISLIN - interface to C++ DISLIN system * Mayavi - interface to Mayavai2, standalone program * gdmodule GD - python wrapper for the GD library. * Gist - wrapper for gist graphics library * pgplot - Wrapper for pgplot. * Py-OpenDX - wrapper for IBM Data Explorer * VTK - wrapper for VTK in C++ * RPy - wrapper for R programming lnaguage * PyX - wrapper for Tex. * Biggles - wrapper for C++ module * Pychart - 100% Python, but last updated 21-Dec-2005. * PyNGL - uses PyNIO, which is in C * pygooglechart - Python interface to the Google Chart LookinAPI, only works in browser So, for pure Python, Pychart is it. I'll have to try it and see if it still works. John Nagle -- http://mail.python.org/mailman/listinfo/python-list
