Saving a web cam captured surface to a bmp file

Now that I have learned what is a surface, I tried to save the surface to a BMP file.  I expected that it might take me hours to do this thing.  But surprisingly it took me only a couple of minutes.  The only bug I made was because I did not know how to specify a name in linux.

And the 2 relevant statements are:

    imageSurface = webCam.get_image()

    pygame.image.save(imageSurface, "/home/pi/fongtoy/testImage.bmp")

lunch time.
