我正在尝试在PHP中使用ImageMagick将PDF转换为图像。初始化构造函数会给我一个“委托错误，找不到指定的文件”。
请注意，从命令行运行转换确实可以。它成功地将PDF的所有页面转换为每页图像。
我尝试过的事情：
卸载ImageMagick和Ghostscript，重新引导，安装Ghostscript（32），重新引导，安装ImageMagick，重新引导
将Ghostscript文件夹的路径添加到Windows中的PATH变量并重新启动（在我检查时当前已添加）
在正确配置ImageMagick并且错误不存在的服务器上运行相同的完全PHP脚本-因此php脚本应该不是问题吗？
让我知道是否应该提供更多信息。在过去的2个小时里，我一直在寻找解决方案，而现在这些想法全都没有了。
谢谢。
此外，我正在Windows 10 XAMPP上运行。

Delegate command file.
Commands which specify
decode="in_format" encode="out_format"
specify the rules for converting from in_format to out_format These
rules may be used to translate directly between formats.
Commands which specify only
decode="in_format"
specify the rules for converting from in_format to some format that
ImageMagick will automatically recognize. These rules are used to
decode formats.
Commands which specify only
encode="out_format"
specify the rules for an "encoder" which may accept any input format.
For delegates other than ps:alpha, ps:color, ps:mono, and mpeg-encode the
substitution rules are as follows:
%i input image filename
%o output image filename
%u unique temporary filename
%# input image signature
%b image file size
%c input image comment
%g image geometry
%h image rows (height)
%k input image number colors
%l image label
%m input image format
%p page number
%q input image depth
%s scene number
%w image columns (width)
%x input image x resolution
%y input image y resolution
