       ppmtv - make a PPM image look like taken from an American TV

       ppmtv dimfactor


       This program is part of Netpbm(1)

       ppmtv reads a PPM image as input and dims every other row of image data down by the speci-
       fied 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.
