18 ppmtv reads a PPM image as input and dims every other row of image data
19 down by the specified dim factor. This factor may be in the range of
20 0.0 (the alternate lines are totally black) to 1.0 (original image).

22 This creates an effect similar to what I've once seen in the video clip
23 'You could be mine' by Guns'n'Roses. In the scene I'm talking about
24 you can see John Connor on his motorbike, looking up from the water
25 trench (?) he's standing in. While the camera pulls back, the image
26 gets 'normal' by brightening up the alternate rows of it. I thought
27 this would be an interesting effect to try in MPEG. I did not yet check
28 this out, however. Try for yourself.
