how to use GDAL to rasterize a set of polygons (represented as paths),
including some links to stack-overflow questions. It isn't a complete
end-to-end solution, but the pieces are there.
Cheers!

I've been searching and reading through source code and google searches
to see if this is possible, but no luck so far. I'm basically trying to
map some data using Basemap, use contourf to map it to an image, and
then put that image in a geotiff (or other format) for use in other GIS
programs.
whatever you wish with them.

You likely need to show() the canvas. I usually do this by calling
fig.canvas.show() before the for loop.
Since you are using a Qt4 backend the canvas used by the figure is a
QWidget, the basic component of a Qt4 GUI. I don't know if there is a
more matplotlib specific way of doing this, but

as a callback, with a main

few/10s of seconds?

Eric,
I installed mpl from git (git clone
git://github.com/matplotlib/matplotlib.git, unless I was suppose to use
one of the branches) and same problem. I looked at my code again and
thought there should be a canvas.draw() before calling
c.copy_from_bbox(a.bbox), but still the same problem.

I'm not sure how experienced you are with multithreaded programs, but
here is some sample code (I mentioned it can get complicated). I
suggest you research Qt4 QThreads and also Qt4 Signals and slots to
better understand the code below. It is a working sample so you should
be able to run it
I don't know what you mean by ApplicationWindow, is that a class or
just a name for the main GUI window. I also don't really know what
calling the graphical application means, but I'm sure the book can help
you more than I can. Again, good luck.

Does anyone know if using the blit method from FigureCanvasQTAgg is not
fully supported? I'm having a problem where I'm animating a plot using
the blit method and I click on/activate the window the background of the
figure disappears (axes and line stay visible). I'm not sure if this is

Fabien,
The GUI not being responsive might be my fault, I've never used a timer
of 0 and processEvents(). I think what might be happening is that when
you call processEvents, the timer of 0 calls your principal function
again, which calls processEvents again, and so on. Try a timer of 2
Yeah I didn't think about suggesting that, but I think it might get
complicated. I think he would have to start a one shot timer to call a
function to set the voltage. Then that function would also start
another one shot timer to call another function that would read from the
sample. That
Hey Fabien,
So you made your principal function run on a timer every 2 seconds? And
by lag do you mean that the GUI is unresponsive? I'm still not seeing
when the loop stops, but what you can do is set the timer at a 0
interval so it will call the principal function as fast as it can (but
If I'm understanding your question correctly and reading your code correctly,
you're asking why the timer method of doing things works, but the principal()
while loop method does not.
I had a couple solutions that involved the main event loop, but I just noticed
2 main things that are probably
I think you forget to set the layout on your central widget.

I do something similar to this where data that I'm plotting in a 2D line
