    if($y==-1)
        $y=$this->y;
    if($this->angle!=0)
        $this->_out('Q');
    $this->angle=$angle;
    if($angle!=0)
    {
        $angle*=M_PI/180;
        $c=cos($angle);
        $s=sin($angle);
        $cx=$x*$this->k;
        $cy=($this->h-$y)*$this->k;
        $this->_out(sprintf('q %.5F %.5F %.5F %.5F %.2F %.2F cm 1 0 0 1 %.2F %.2F cm',$c,$s,-$s,$c,$cx,$cy,-$cx,-$cy));
