## 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 basename.V
       as output.  These files are the subsampled raw YUV representation of the input pixmap, as re‐
       quired  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.
