The wxPython Debian packages do not include the development headers required to build the WXAgg accelerator module. The WXAgg backend will work just fine without it, so you should disable the module by editing setup.cfg and uncommenting the line "wxagg = False" in the "gui_support" section. Please let me know if you haven't created a setup.cfg file and are receiving this error straight "out of the box", as that's indicative of a bug in the build system. Thanks! Ken
This is a known bug in the Debian packaging of wxPython. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=326440 There are some workarounds mentioned in that post. Personally, I usually end up building wxPython from source (which doesn't have this header file problem) to keep up with its fairly frequent bugfixes anyway. If you'd prefer to stick with deb packages, you could *try* the wxPython-provided .deb packages (i.e. not the Debian-provided ones) here, though I don't know whether they also exhibit this problem: http://wiki.wxpython.org/InstallingOnUbuntuOrDebian Cheers, Mike Matthias Michler wrote: > Hello list, > > I was not up to date with my installation and I tried to use the latest svn > version (trunk) on my Debian etch.

Hello list, I was not up to date with my installation and I tried to use the latest svn version (trunk) on my Debian etch. I have a problem to build matplotlib including support for wxPython as backend. The output is attached below. Actually I cannot find a file "wxPython.h" on my system. Can anybody give me a hint what I'm doing wrong? How can I find wx headers and tell their location matplotlib? best regards and thanks in advance for any hint, Matthias $ python setup.py build

(which > will then be processed later) I have very recently written some code that creates a binary mask (2-D array) of an irregular polygon given the co-ordinates of the corners. It successively uses equations of the line segments between pairs of neighbouring points around the polygon edge and sets the pixels on the inner side of those lines. I doubt it's the most efficient code, but seem so to work, and I'm happy to send you a copy it if it might be helpful. > Has anyone tried this? What is the easiest way > to start? I'm using wxpython for the GUI. It's relatively easy to capture successive mouse clicks using mpl, and use those co-ordinates for the polygon calculating code. An example of capturing mouse co-ordinates is in the cookbook: http://www.scipy.org/Cookbook/Matplotlib/Interactive_Plotting.

Hi, I'm looking for a way to do masking of an Image.. I need to be able to make a circle / box or a user made polygon on an image using the mouse and retrieve the pixellocations of all pixels inside the masked area.. (which will then be processed later) Has anyone tried this? What is the easiest way to start? I'm using wxpython for the GUI. Thanks! Soren Nielsen
Hello, I would like to know if there is a way to plot "broken" axis using matplotlib. I would like to plot only the left and the right part of a spectrum, and put a mark on the X axis to show that the axis scaling is interrupted here. Thank you, -- Darckense http://darckense.online.fr
