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.
