终于有空整理一下关于WPF的2D图形化实现的代码样例了。
目前阶段，已经把功能封装成了一个控件，主要有一下的功能
1、图形对与滚动条支持的功能。
2、图形中的图元同步的移动功能。
3、图形中的图元同步的缩放。
4、图形中的图元对象的分层的概念（层可以套层，图元下面加载子图元）。
5、图形中的图元的选中功能。
6、为图形中的图元提供虚拟图层（提供缓创建功能）功能
7、加载自定义图形的支持，并且同步移动，缩放功能。
8、图形中的图元闪烁功能。
9、图元的移动功能。
10、框选区域放大功能。
基本就是上面的功能，有些功能，相隔时间久了，偶有可能忘记，只能考大家发现了。
基于NET4.0 开发工具VS2010
下面讲一下主要功能的实现的代码
加载对层和加载对象
加载对层和加载对象

先写这些。。哈哈哈。。。
困了。。去休息一下。。。
