I tried Root’s advice and with the get_data method and GTK (without Agg) I got decent speed -- 30 fps (display speed,  without the calculations overhead). The combination of matplotlib and glumpy resulted in 88 fps.

 I think I’ll have a solutionif glumpy lack of documentation will net get in the way.

 Thank you all for the useful advices,

    Nadav.

Have a look at glumpy: http://code.google.com/p/glumpy/
It's quite simple and very fast for images (it's based on OpenGL/shaders).

I have an application which generates and displays RGB images as rate of several frames/seconds (5-15). Currently I use Tkinter+PIL, but I have a problem that it slows down the rate significantly. I am looking for a fast and easy alternative.

Platform: Linux
I prefer tools that would work also with python3

I looked at the following:
1. matplotlib's imshow: Easy but too slow.
2. pyqwt: Easy, fast, does not support rgb images (only grayscale)
3. pygame: Nice but lacking widgets like buttons etc.
4. PyQT: Can do, I would like something simpler (I'll rather focus on computations, not GUI)
