SYNOPSIS

DESCRIPTION

16       This program is part of Netpbm(1).
17
18       ppmtv reads a PPM image as input and dims every other row of image data
19       down by the specified dim factor.  This factor may be in the  range  of
20       0.0 (the alternate lines are totally black) to 1.0 (original image).
21
22       This creates an effect similar to what I've once seen in the video clip
23       'You could be mine' by Guns'n'Roses.  In the scene  I'm  talking  about
24       you  can  see  John  Connor on his motorbike, looking up from the water
25       trench (?)  he's standing in.  While the camera pulls back,  the  image
26       gets  'normal'  by  brightening  up the alternate rows of it. I thought
27       this would be an interesting effect to try in MPEG. I did not yet check
28       this out, however.  Try for yourself.
