不管你是windows还是linux,要实现PDF文件转换成png还是jpg首先,都安装Imagick扩展。这扩展网上都有详细的安装教程,灵活的运用安装。下面是实现功能的代码:

 $fileName1 = 'CZ2016-01-01/o_1ak57jr6ms741efo1ndk8b4daic.jpg'; $path1 = "http://img.qkhl.net/test"; chmod($path1.'/'.$fileName1, '-rwxrwxrwx' );//赋给文件权限(777) $data_i =  pdf2png($fileName1, $path1); die('{"status" s: "success", "result": {"imgpath" : "' . $data_i . '"}}');//返回参数function pdf2png($pdf,$path1,$page=-1){   if(!extension_loaded('imagick'))   {       return 4;   }   if(!file_exists($pdf))   {       return 5;   }   $im = new Imagick();   $im->setResolution(60,60); //设置分辨率   $im->setCompressionQuality(10);//设置图片压缩的质量   if($page==-1)  {    $ss =   $im->readImage($pdf);   }   else{      $im->readImage($pdf."[".$page."]");//从文件名读取图像       return 7;   }       $im->setImageFormat('jpg'); //为图片设置指定的格式       $filename1 = $path1."/". md5(time()).'.jpg';       $dd = $im->writeImage($filename1);       // return '阻住';       if($dd == true)//把图片写入指定的文件       {          // return 'yes';           $return = $filename1;       } else{            return '失败';       }   return $return;}

注意当我们引入函数的时候 pdf2png($pdf,$path1,$page=-1)当直接引用。还有就是路径必须写正确,否则会转换失败。
