• 在OpenCV2.2后的版本中没有CvvImage类的解决方法(及出现错误:IntelliSense: 未定义标识符 "CvvImage" )


    首先在你的解决方案资源管理器中的头文件和源文件下分别添加 CvvImage.cpp 如下图:

     

    view类头上加个#include "CvvImage.h"  头文件,应该就可以解决了。

    下面是源代码:

     CvvImage.h.h

    CvvIm
    class  CvvImage
    {

     virtual bool  Load( const char* filename, int desired_color = 1 );

     
     virtual bool  LoadRect( const char* filename,
      int desired_color, CvRect r );

    #if defined WIN32 || defined _WIN32
     virtual bool  LoadRect( const char* filename,
      int desired_color, RECT r )
     {
      return LoadRect( filename, desired_color,
       cvRect( r.left, r.top, r.right - r.left, r.bottom - r.top ));
     }
    #endif

     
     virtual bool  Save( const char* filename );

     
     virtual void  CopyOf( CvvImage& image, int desired_color = -1 );
     virtual void  CopyOf( IplImage* img, int desired_color = -1 );

     IplImage* GetImage() { return m_img; };
     virtual void  Destroy(void);

     
     int Width() { return !m_img ? 0 : !m_img->roi ? m_img->width : m_img->roi->width; };
     int Height() { return !m_img ? 0 : !m_img->roi ? m_img->height : m_img->roi->height;};
     int Bpp() { return m_img ? (m_img->depth & 255)*m_img->nChannels : 0; };

     virtual void  Fill( int color );

     
     virtual void  Show( const char* window );

    #if defined WIN32 || defined _WIN32
     
     virtual void  Show( HDC dc, int x, int y, int width, int height,
