我见过用于打开的COM类在本地计算机上启动应用程序并将ppt / pptx保存为图像...但是在远程计算机上，COM类不存在。
I've seen the COM class used to open up the application on a local machine and save the ppt/pptx as images ... but on a remote machine, the COM class does not exist.

推荐答案
服务器是Amazon EC2实例，因此在大多数情况下，它是唯一的CLI。
The server is an Amazon EC2 instance, so for the most part, its only CLI.
我所做的是：
我已经安装了用于在PHP中使用 exec（）将文档转换为PDF。
I've installed Libreoffice (headless) for converting documents to PDF's using exec() in PHP.
从那里我使用ghostscript（已安装在服务器上）通过使用 exec（）从生成的PDF中提取图像。
From there I use ghostscript (already installed on the server) to extract images from the generated PDF by using exec() as well.
