一个音频发烧友也许会拿nano的音频输出和高端的配件相比来挑刺，不过大多数iPod nano的所有者都只是在路上用它听听音乐而已，在这种情况下，它的音质很不错了。

To enable applications to place output in memory rather than sending it to an actual device, use a special device context for bitmap operations called a memory device context.

要使程序能输出到内存中，而不是实际的设备上，使用操作位图的特殊设备环境，称之为内存设备环境。

GDI output functions can be used with a memory device context only if a bitmap has been created and selected into that context.

GDI的输出函数只有当内存设备环境上有了位图画布之后，才能进行输出。
