代码说明：

GDI是位于应用程序与不同硬件之间的中间层，这种结构让程序员从直接处理不同硬件的工作中解放出来，把硬件间的差异交给了GDI处理。 GDI+是GDI的下一个版本，它进行了很好的改进，并且易用性更好。-GDI is located in different applications and hardware between the middle layer, this structure allows programmers from different hardware directly in the work of liberation, the differences between hardware to handle the GDI. GDI GDI is the next version, it had a very good improvement, and better ease of use.
