While you can certainly use the Windows GDI as a high-level vector drawing system, you can also use it for relatively low-level pixel manipulation.

当你的确可以将Windows GDI用作高层次的矢量绘图系统时，你也可以将它用于相关的低层次的像素操作。

Although some graphics languages don't let you use pixel coordinates, Windows GDI lets you use either system (as well as additional coordinate systems based on physical measurements).

尽管一些图形语言不让你用像素坐标，但是Windows GDI让你用任意一个系统(甚至传统的基于物理度量的坐标系统)。
