ppmtv


SYNOPSIS
       ppmtv dimfactor [ppmfile]

DESCRIPTION
       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 I've once seen in the video clip
       'You could be mine' by Guns'n'Roses. In the scene I'm talking about you
       can  see John Connor on his motorbike, looking up from the water trench
       (?)  he's 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.
