NAME

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

SYNOPSIS

       ppmtv dimfactor

       [ppmfile]

DESCRIPTION

       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 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.

OPTIONS

       There are no command line options defined specifically for ppmtv, but it recognizes the options common to
       all programs based on libnetpbm (See  Common Options .)
