GDI+高级编程(C#)

GDI+高级编程(C#) The code needed to actually draw to the screen is often quite simple, and it relies on a technology called GDI+. GDI+ consists of the set of .NET base classes that are available for the purpose of carrying out custom drawing on the screen. These classes are able to arrange for the appropriate instructions to be sent to the graphics device drivers to ensure the correct output is placed on the monitor screen (or printed to a hard copy). Just as for the rest of the .NET base classes, the GDI+ classes are based on a ver y intuitive and easy to use object model. Although the GDI+ object model is conceptually fairly simple we still need a good understanding of the underlying principles behind how Windows arranges for items to be drawn on the screen in order to draw effectively and efficiently using GDI+.
