ppmntsc(1)

NAME
       ppmntsc  -  make a portable pixmap look like taken from an
       American TV

SYNOPSIS
       ppmntsc 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.
