Hello,

<comment>
A little bit off-topic, as this talk about OpenCV...
Next questions about OpenCV should maybe done on the OpenCV mailing

here is the Python code for doing this:
  # set the wanted image size from the camera
  highgui.cvSetCaptureProperty (capture, highgui.CV_CAP_PROP_FRAME_WIDTH, 320)
  highgui.cvSetCaptureProperty (capture, highgui.CV_CAP_PROP_FRAME_HEIGHT,240)

I will let you make the C code as an exercice. ;-)

Have a nice night.
