SYNOPSIS
ppmtoyuvsplit basename [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces 3 raw files basename.Y,
basename.U and basename.V as output. These files are the subsampled
raw YUV representation of the input pixmap, as required by the Stanford
MPEG codec. The subsampling is done by arithmetic mean of 4 pixels col-
ors into one. The YUV values are scaled according to CCIR.601, as as-
sumed by MPEG.
