如何在vc6中使用GDI+?

   default:
      return DefWindowProc(hWnd, message, wParam, lParam);
   }
} // WndProc然后下载 platform SDK，Runtime GDI+,设置include lib路径,link  gdiplus.lib

先安装了platform 其中包含gdi+将include和lib目录的路径添加到options中。并将他们都移到最前面，比较优先。在需要使用的地方#include <gdiplus.h>和#progma comment(lib,"gdiplus.lib")就可以使用了

别忘了，如果没有下载Runtime GDI+的话，没有gdiplus.dll,是无法运行的！

谁能谈谈GDI+的好处（和GDI比有什么强大的功能？）
最好有具体的实例？

新版的gdi+ 1.1已经提供了简单的图像处理功能，包括亮度，对比度，色饱和度，gamma调整
还有红眼校正，高斯模糊，色平衡，锐化，着色等功能。但是还没有提供下载
至于旧版的，自己看msdn吧，所有例子代码都有的http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/GDIPlus/GDIPlusReference/Classes/

老弟英语够可以的，呵呵呵
