ImageMagick / Imagick使用本机PHP API将PDF转换为JPG [英] ImageMagick/Imagick convert PDF to JPG using native PHP API

问题描述

我正在尝试将PDF文件转换为PNG。它在命令行中运行良好（我安装了GhostScript 8.64）。但是从PHP我遇到了问题：

I’m attempting to convert PDF files into PNGs. It works great from the command line (I do have GhostScript 8.64 installed). But from PHP I’m having a problem:

代码：

$im = new Imagick($pdf_file); // this is where it throws the exception below

输出：

Fatal error: Uncaught exception ‘ImagickException’ with message ‘Postscript delegate failed `23_1235606503.pdf’: No such file or directory @ pdf.c/ReadPDFImage/612′ in get_thumbnail.php:93
Stack trace:
\#0 get_thumbnail.php(93): Imagick->__construct(’…’)

等。等等。

我不确定我在这里做错了什么，但我怀疑它与某处的服务器配置有关。我正在运行：
Apache 2.2.11
PHP 5.2.8
ImageMagick 6.4.8-9
GhostScript 8.64

I'm not sure what I'm doing wrong here, but I suspect it has something to do with my server configuration somewhere. I'm running: Apache 2.2.11 PHP 5.2.8 ImageMagick 6.4.8-9 GhostScript 8.64

推荐答案

最后想出来了。 GhostScript可执行文件（ gs ）不在Apache的环境路径中。它在 / usr / local / bin 中。虽然我尝试了几种方法将 / usr / local / bin 添加到路径中，但我没有成功。我最终在 / usr / bin目录中为 gs 添加了一个符号链接。现在一切都很完美。

Finally figured this out. The GhostScript executable (gs) wasn't in Apache's environment path. It was in /usr/local/bin. Though I tried several ways to add /usr/local/bin to the path, I did not succeed. I ended up putting a symlink for gs in the /usr/bin directory. Now everything works perfectly.
