使用Imagick 生成图片

解决了图片写中文文字乱码问题，添加支持的字体

public function getPic(){
    
      header('Content-Type: text/html; charset=utf-8');
    
      $text = '中粮屯河（sh600737）';//中粮屯河（sh600737）
    
      $watermark = '305988103123zczcxzas';
    
      $len = strlen($text);
    
      $width = 10.5*(($len-8)/3*2+8);
    
      $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;
    
      $style['font_size'] = 20;
    
      $style['fill_color'] = '#FF0000';
    
      $style['font'] = './msyh.ttf'; ///微软雅黑字体 解决中文乱码
    
      //$text=mb_convert_encoding($text,'UTF-8'); //iconv("GBK","UTF-8//IGNORE",$text);
    
      $this->add_text($imagick,$text, 2, 20, 0,$style);
    
      header ( 'Content-type: ' . strtolower ($imagick->getImageFormat ()) );
    
      echo $imagick->getImagesBlob ();
    
    }
    
    // 添加水印文字
    
    public function add_text(& $imagick, $text, $x = 0, $y = 0, $angle = 0, $style = array()) {
    
      $draw = new ImagickDraw ();
    
      if (isset ( $style ['font'] ))
    
       $draw->setFont ( $style ['font'] );
    
      if (isset ( $style ['font_size'] ))
    
       $draw->setFontSize ( $style ['font_size'] );
    
      if (isset ( $style ['fill_color'] ))
    
       $draw->setFillColor ( $style ['fill_color'] );
    
      if (isset ( $style ['under_color'] ))
    
       $draw->setTextUnderColor ( $style ['under_color'] );
    
      if (isset ( $style ['font_family'] ))
    
       $draw->setfontfamily( $style ['font_family'] );
    
      if (isset ( $style ['font'] ))
    
       $draw->setfont($style ['font'] );
    
      $draw->settextencoding('UTF-8');
    
      if (strtolower ($imagick->getImageFormat ()) == 'gif') {
    
       foreach ( $imagick as $frame ) {
    
        $frame->annotateImage ( $draw, $x, $y, $angle, $text );
    
       }
    
      } else {
    
       $imagick->annotateImage ( $draw, $x, $y, $angle, $text );
    
      }
    
    }
