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 ⟨index.html#commonoptions⟩ .)
