调整 10.10 桌面更改 Python 脚本

调整 10.10 桌面更改 Python 脚本

我不擅长 Python,目前我使用的脚本是基于https://gist.github.com/gregneagle/6957826

我希望对以下脚本中的桌面图像字典键选项进行一项更改,但我不确定正确的代码是什么。

当前代码

options = {}

我想要获得的是“NSWorkspaceDesktopImageAllowClippingKey”的 NO 值(参考:https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWorkspace_Class/index.html#//apple_ref/doc/constant_group/Desktop_Image_Dictionary_Keys

我的最终目标是让这个程序将 10.9 和 10.10 中的桌面图片设置为“适合屏幕”,而不是“填满屏幕”(它似乎总是默认设置为“填满屏幕”)。它是 NetRestore 图像实用程序的一部分,所以我需要自动执行此操作,因为该信息包含在 ByHost 首选项中。

谢谢你!
