GDI＋是.net提供的一个强大的图像处理接口，但目前大部分书籍还是停留在GDI的SDK（或VC）的程序。我在SDK的框架上添加了不到20行的代码实现了用GDI＋引入图像，这可比以前的GDI编写近百行代码简便多了，有兴趣的朋友可以下载，包括可执行程序和源代码。（用的是.net外壳）。-yes. Net provide a powerful image processing interface, but the majority of books are still stuck in the SDK GDI (or VC) procedures. In the framework SDK add less than 20 lines of code to achieve the introduction of using GDI+ images, comparable to the previous GDI prepared nearly 100 lines of code more simple, interested friends can be downloaded, including the executable and source code. (With a yes. Net shell).
