Here's a fragment that might help, that might get you started at least:

$fileheader_printed = 0;


sub hash_figs
{
  $figfile = $_[0];
  open (fp, $figfile) || die ("Can't open $figfile.\nExiting");

  $nodecount=0;
  $numpages=0;
  $ignore_text = 0; #Used to exclude page footer
  while (<fp>)
  {
    if (/^%!PS-Adobe/) #Start of Page Marker
    {
      if (++$numpages == 2) #Header is first element in list
      {
        if (!$fileheader_printed)
        {
          print @linelist; #print header
          $fileheader_printed = 1;
        }
      }
      else
      {
        if ("insert reg expr here")
        {
          print @linelist; #Print Figure
        }
        if ($nodecount++%80==0)
        {
          print STDERR "\n      ";
        }
      }
      $currfig="junk";
      @linelist = ();
    }
    elsif(m/^%%Title:/) 
    {
      $currfig = uc $1; 
    }
    elsif (/\[100 0 0 \-100 0 0\]\/Times\-Roman MF/) #Ignore Page Foot
+er
    {
      $ignore_text = 1;
    }
    elsif (/Preamble/) #Ignore Page Footer
    {
      $ignore_text = 0;
    }
    if (not $ignore_text)
    {
      push (@linelist, $_);
    }
  }
}
