PHP imagick出现PDF问题

问题描述

我正在尝试将PDF的第一页转换为图像文件.

I am trying to convert the first page of a PDF to an image file.

我有以下代码:

$im = new imagick('/images/test.pdf[0]');

$im->setImageFormat("jpg");
$page=$im->queryFormats();
echo "<pre>";
 print_r ($page);
echo "</pre>";

但是，我收到一条错误消息:

However, I get an error message saying:

Uncaught exception 'ImagickException' with message 'unable to open image

如果我更改:

$im = new imagick('/images/test.pdf[0]');

收件人:

$im = new imagick('/images/test.pdf');

我收到以下错误:

Uncaught exception 'ImagickException' with message 'Unable to read the file

我确定我的PDF路径正确，并且不确定如何解决此问题.谁能帮我这个忙吗?

I am sure the path to my PDF is correct and I'm not sure how to solve this. Can anyone help me out with this?

推荐答案

驱动器的根目录中是否有/images文件夹?请记住-imagick在PHP中运行，并且不知道您网站的URL空间结构是什么.您需要使用本地文件系统路径，例如

Do you have a /images folder in the ROOT of your drive? Remember - imagick is running within PHP and has no clue whatsoever what your site's URL-space structure is. You need to use the local file system path, e.g.

$im = new imagick('/path/to/example.com/html/images/test.pdf[0]');
