为了支持c++的多态性，才有了动态绑定和静态绑定。理解他们的区别有助于更好的理解多态性，以及在编程的过程中避免犯错误。
需要理解四个名词：
1、对象的静态类型：对象在声明时采用的类型。是在编译期确定的。
2、对象的动态类型：目前所指对象的类型。是在运行期决定的。对象的动态类型可以更改，但是静态类型无法更改。
关于对象的静态类型和动态类型，看一个示例：
class B
{
}
class C : publ]]>https://blog.youkuaiyun.com/backo880607/article/details/6439992https://blog.youkuaiyun.com/backo880607/article/details/6439992backo880607Mon, 23 May 2011 16:04:00 +0800
       图片状态（裁剪区域、变形、质量设置等）存储于Graphics对象中。GDI+ 允许您采用一个容器临时替换或者扩充一个Graphics对象的状态。调用Graphics对象的BeginContainer方法开始一个容器，直至调用EndContainer方法终止一个容器。在这期间，您对于属于该容器的Graphics对象进行的任何状态改变都不会覆盖掉Graphics对象现存的状态。

         GDI+ 提供世界变换和页面变换功能，可让您转换 (旋转、缩放、平移等) 所绘制的项目。这两种转换功能适用于各种坐标系统。坐标系统类型(Types of Coordinate Systems)
GDI+使用三个坐标空间：世界、页面和设备。世界坐标 (World Coordinate) 是用来制作特定绘图自然模型的坐标。页面坐标 (Page Coordinate) 则是指绘图接口 (例如窗体或控件) 使用的坐标系统。设备坐标 (Device Coordin]]>https://blog.youkuaiyun.com/backo880607/article/details/6400339https://blog.youkuaiyun.com/backo880607/article/details/6400339backo880607Fri, 06 May 2011 16:55:00 +0800 
 
         Microsoft Windows GDI+提供了Image类用于进行光栅图像（位图）和矢量图像（图元文件）。Bitmap类和Metafile类都是继承自Image类。Bitmap类通过提供加载、储存和管理光栅图像的其它方法，增强了Image类的功能。Metafile类别通过提供记录和检验矢量图像的其它方法，增强Image类别的功能。位图类型(Types of Bitmaps)
位图是像素的矩形阵列，而每个像素都由位数组指定其颜色。单个像素]]>https://blog.youkuaiyun.com/backo880607/article/details/6370860https://blog.youkuaiyun.com/backo880607/article/details/6370860backo880607Thu, 28 Apr 2011 23:29:00 +0800

         一个闭合图形比如矩形和椭圆包含一个边框和内部区域。边框是由Pen对象绘制，而内部区域由Brush对象进行填充。Microsoft Windows GDI+提供几种画刷类用于填充闭合图形的内部区域：SolidBrush、HatchBrush、TextureBrush、LinearGrad]]>https://blog.youkuaiyun.com/backo880607/article/details/6369166https://blog.youkuaiyun.com/backo880607/article/details/6369166backo880607Thu, 28 Apr 2011 11:30:00 +0800https://blog.youkuaiyun.com/backo880607/article/details/6330152https://blog.youkuaiyun.com/backo880607/article/details/6330152backo880607Mon, 18 Apr 2011 00:27:00 +0800 
         GDI+的矢量绘图部分被用来绘制线条、绘制曲线和填充图形。矢量图概览(Overview of Vector Graphics)
         Microsoft Windows GDI+在一个坐标系统中绘制线条、矩形和其它图形，你可以选择各种不同的坐标系统，默认的坐标系统原点为左上角，X轴指向右，Y轴指向下，其度量单位为像素。

Microsoft Windows GDI+ 不同于GDI体现在2个方面。第一，GDI+通过提供新的功能扩展了GDI的特性，比如渐变画刷和半透明混合。第二，编程模型的改进使得图形开发更加简单和灵活。相对于GDI的新特性渐变画刷（Gradient Brushes）
         GDI+通过提供用于填充图形、路径、区域的线性渐变和路径渐变画刷来扩展了GDI的功能。渐变画刷同样能够被用来绘制线条、曲线、路径。当您采用线性渐变画刷填充图形的时候，颜色将在穿越该图形时逐渐改变]]>https://blog.youkuaiyun.com/backo880607/article/details/6319432https://blog.youkuaiyun.com/backo880607/article/details/6319432backo880607Wed, 13 Apr 2011 00:19:00 +0800    从今天开始，根据MSDN中GDI+文档正式学习GDI+图形界面编程技术。GDI+概述：
Microsoft Windows GDI+ 是Windows XP和Windows Server 2003操作系统的子系统，它负责在屏幕和打印机上显示信息。GDI+是一个应用程序编程接口（API），它由一组C++类实现。基于Microsoft Win32的应用程序不能直接访问图形硬件，而是通过GDI+来协调设备驱动和程序动作的交互。GDI+同样支持Microsoft Win64。
