Applescript-如何将图像附件从Outlook转换为PDF并保存到文件夹

Question

我想将图像附加到电子邮件中的Outlook文件夹中，将它们转换为PDF并将其保存到文件夹中。到目前为止，我拥有的代码会获取附件并将​​其保存到文件夹中，但是我不知道要添加什么内容才能将其转换为PDF。

set saveToFolder to POSIX path of "/Users/userXXX/Documents/DestinationFolder/"

tell application "Microsoft Outlook"
    set srcFolder to folder "ImageFolder" of default account
    set selectedMessages to messages of srcFolder
    repeat with msg in selectedMessages
        set msgsender to the sender of msg
        set senderaddress to the address of msgsender
        set attFiles to attachments of msg
        repeat with f in attFiles
            set attName to (get the name of f)
            log attName
            set saveAsName to saveToFolder & attName
            log saveAsName
            save f in POSIX file saveAsName
        end repeat
    end repeat
end tell
