public function getPic(){

  $height = 26;
  $imagick = new Imagick();
  $color_transparent = new ImagickPixel(\'#ffffff\'); //transparent 透明色
  $imagick->newImage($width, $height, $color_transparent, \'jpg\');
  //$imagick->borderimage(\'#000000\', 1, 1);
  $style[\'font_size\'] = 12;
  $style[\'fill_color\'] = \'#000000\';
  for($num= strlen($watermark); $num>=0; $num--){
   $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 30, 1,$style);
   $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 5, 1,$style);
  }
  //return;

  //$text=mb_convert_encoding($text,\'UTF-8\'); //iconv(\"GBK\",\"UTF-8//IGNORE\",$text);
  $this->add_text($imagick,$text, 2, 20, 0,$style);
