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

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  colors
       into one. The YUV values are scaled according to CCIR.601,
       as assumed by MPEG.
