C#图片中画中国风图案

今天我要用C#语言画一个图案，具有中国风的图案。并镶在图片四周。

效果如下图所示。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

单个样式如上图所示

我们先建立一个应用程序。

命名TestChinaStyle

拖几个控件。

在Form_Loding事件中加入这样的代码。

155         }
156     }
157 }

运行就得到第二张图片的效果，

通过旋转的基点和旋转的角度就可以得到相应的另外三个角的图案。

在通过DrawImage方法将图片画在截图之中。

直接上关键性的代码

其他的略过。
