NAME
       ppmtoyuvsplit - convert a portable pixmap into 3 subsampled raw YUV files

SYNOPSIS
       ppmtoyuvsplit basename [ppmfile]

DESCRIPTION
       Reads  a  portable pixmap as input.  Produces 3 raw files basename.Y, basename.U and base-
       name.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 colors into one. The YUV values are scaled according to CCIR.601,  as  assumed
       by MPEG.
