如何使用 AppleScript 和 Acrobat Pro 从 PDF 中自动提取页面?

我是 AppleScript 的新手，但我正在尝试创建一个脚本，该脚本将遍历文件夹中的所有 PDF，将页面提取到单独的文件中.我的计划是结合使用 Automator 和 AppleScript.

I'm new to AppleScript, but I am trying to create a script that will go through all PDFs in a folder extracting the pages into separate files. My plan is to use a combination of Automator and AppleScript.

到目前为止，我的 AppleScript 是:

My AppleScript so far is:

tell application "Adobe Acrobat Pro"
    open theFile
    set numPages to (count active doc each page)
    --execute the extraction here
end tell

Acrobat Pro 中的命令位于 Options >提取页面...，我可以在其中指定页面范围并提取到单独的文件.但是，我似乎找不到使用 AppleScript 中的 Acrobat Pro 词典来执行此操作的方法.

The command in Acrobat Pro is under Options > Extract Pages..., where I can specify the page range and to extract to separate files. However, I can't seem to find a way to do this with the Acrobat Pro Dictionary in AppleScript.

有一个执行菜单项的 execute 命令，但我似乎无法让它工作(我也不确定要使用的语法；即 execute "选项:提取页面..."?).对此有什么帮助吗?

There is an execute command that executes a menu item, but I can't seem to get it working (I'm also not sure of the syntax to use; i.e. execute "Options:Extract Pages..."?). Any help on this?
