CvvImage类

      从OpenCV 2.2.0开始，OpenCV取消了CvvImage这个类。可是今天要用到，可以自己加入到工程中。

首先，找到CvvImage的原代码。我在网上已经找到了，具体代码如下。

      这是CvvImage.h文件。

   int Bpp() { return m_img ? (m_img->depth & 255)*m_img->nChannels : 0; };
   virtual void  Fill( int color );
   /* draw to highgui window */
   virtual void  Show( const char* window );

      找到原文件之后就好办了。你就可以自己添加到自己的所需要的工程中去了。

其次：保存文件

      将上面的文件要保存起来，分别将其粘贴在.txt文件中，然后改掉名字为：CvvImage.h 和 CvvImage.cpp

最后：添加CvvImage文件

打开solution Explorer ，右击Header files，添加CvvImage.h; 再右击Source files 添加 CvvImage.cpp

如图所示：
