ppmtv - make a portable pixmap look like taken from an American TV
ppmtv dimfactor [ppmfile]
Reads a portable pixmap as input. Dims every other row of image data down by the specified dim factor. This factor may be in the range of 0.0 (the alternate lines are totally black) to 1.0 (original image).
This creates an effect similar to what Ive once seen in the video clip You could be mine by GunsnRoses. In the scene Im talking about you can see John Connor on his motorbike, looking up from the water trench (?) hes standing in. While the camera pulls back, the image gets normal by brightening up the alternate rows of it. I thought this would be an interesting effect to try in MPEG. I did not yet check this out, however. Try for yourself.
