imagick readImage 陷入系统错误事件黑洞

Question

我正在尝试安装 imagick（到目前为止这不是一件容易的事，但是在 https://mlocati.github.io/articles/php-windows-imagick.html 上使用 [filter] 帮助很大）和运行在我的 WAMP/Windows10/PHP7.0 webapp，但我运行在 readImage() 调用中陷入了黑洞（日志文件只上升到 'checkpoint 2'）。

查看 Windows 系统事件日志，我可以看到错误级别应用程序事件读取：

Faulting application name: httpd.exe, version: 2.4.23.0, time stamp: 0x5776399f

当运行通过我的 WAMP

以下代码时出现此错误

<?php
class Test  {
public function doTrace($msgTx) {
    $dt=date('[D M d H:i:s Y]', gmdate(time()));
    error_log($dt.$msgTx."\n",3, "C:/test.log" );
}
public function doTest() {
    $fn='C:/test.pdf'; 
    if ( file_exists($fn) ) {
        $im = new Imagick();
        $this->doTrace("checkpoint 1");
        $im->setResolution(300, 300); 

        $this->doTrace("checkpoint 2");
        $im->readImage($fn."[0]");    //[0] for the first page

        $this->doTrace("checkpoint 3");
        $im->setImageFormat('png');

        $this->doTrace("checkpoint 4");
        header('Content-Type: image/png');
        echo $im;

        $this->doTrace("checkpoint 5");
    }
    else {
        echo "Did not find $fn";
    }
}
}

$try = new Test();
$try->doTest();

?>

我只是在尝试 readImage (http://php.net/manual/en/imagick.readimage.php#116812) 的手动输入版本，所以这里有什么问题吗？我是否错误地安装了 Imagick (php_imagick-3.4.3-7.0-ts-vc14-x64) 还是其他原因？（注意，我可以让 IM 进行一些简单的测试）

我的 phpinfo() 读取：

因此，在没有明显解决方案的情况下，我决定尝试不同的方向，看看是否可以运行通过命令行转换命令。这让我不得不安装 Ghostscript (https://www.ghostscript.com/download/gsdnld.html)。

现在安装了 Ghostscript，PHP 似乎可以正常工作了 - 我得到了 PDF 第一页的图像。

我是否在安装说明中遗漏了这一点（我不记得提到过 Ghostscript）？
