在windows下安装完后提示:
Fatal error: Trying to clone an uncloneable object of class Imagick in C:\www\hx\pdf_to_png.php on line 17

使用IIS和Apache均会有这个提示。经多次测试后,发现两种解决方法:

1.php.ini中; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
zend.ze1_compatibility_mode = Off

默认是On,改为Off后,即可解决。

2.使用imagick::...这种方法调用。
即$im->setResolution(120, 120);可以改写为:
imagick::setResolution(120, 120);


如果其它扩展出现这类错误,一般也是可以使用这两种方法解决的。

附pdf转png的程序代码片断:

复制代码 代码如下:


        function pdf2png($pdf, $filename, $page=0) {         
            if (!extension_loaded('imagick')) {
                exit('no imagick');
                return false;               
            }
            if (!file_exists($pdf)) {
                return false;
            } 
            $im = new Imagick();
            $im->setResolution(120, 120);
            $im->setCompressionQuality(100);
            $im->readImage($pdf . "[" . $page . "]");
            $im->setImageFormat('png');
            $im->writeImage($filename);
            $im->readImage($filename);
            $im->resizeImage(120, 150, Imagick::FILTER_LANCZOS, 1);
            $im->writeImage($filename);
            return $filename;
        }
