NAME¶
ppmtv - make a portable pixmap look like taken from an American TV
SYNOPSIS¶
ppmtv
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.
