在VS中通过MFC图片控件显示视频

在opencv2.0以上版本之后，就没有对CvvImage类的使用，所以在有VS编程实现MFC显示视频或者图像时候，必须找到CvvImage类头文件，以及源文件加入到编程的文件中，并且添加到工程中去。之后便可以使用CvvImage类了。

下面是CvvImage.h

#pragma once
#ifndef CVVIMAGE_CLASS_DEF
#define CVVIMAGE_CLASS_DEF
#include "opencv.hpp"
/* CvvImage class definition */
class  CvvImage
{
public:
    CvvImage();
    virtual ~CvvImage();
    /* Create image (BGR or grayscale) */
    virtual bool  Create( int width, int height, int bits_per_pixel, int image_origin = 0 );
    /* Load image from specified file */
    virtual bool  Load( const char* filename, int desired_color = 1 );
    /* Load rectangle from the file */
    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
    /* Save entire image to specified file. */
    virtual bool  Save( const char* filename );
    /* Get copy of input image ROI */
    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);
    /* width and height of ROI */
    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 );
    /* draw to highgui window */
    virtual void  Show( const char* window );

#if defined WIN32 || defined _WIN32
    /* draw part of image to the specified DC */
    virtual void  Show( HDC dc, int x, int y, int width, int height,
        int from_x = 0, int from_y = 0 );
    /* draw the current image ROI to the specified rectangle of the destination DC */
    virtual void  DrawToHDC( HDC hDCDst, RECT* pDstRect );
#endif
protected:
    IplImage*  m_img;
};
typedef CvvImage CImage;
