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。

#pragma once

class  CvvImage

{

public:

   virtual bool  Create( int width, int height, int bits_per_pixel, int image_origin =  );

   /* Load image from specified file */

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

   /* 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 = - );

   virtual void  CopyOf( IplImage* img, int desired_color = - );

   IplImage* GetImage() { return m_img; };

   virtual void  Destroy(void);

   /* width and height of ROI */

   int Width() { return !m_img ?  : !m_img->roi ? m_img->width : m_img->roi->width; };

   int Height() { return !m_img ?  : !m_img->roi ? m_img->height : m_img->roi->height;};

   int Bpp() { return m_img ? (m_img->depth & )*m_img->nChannels : ; };

   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 = , int from_y =  );

   /* draw the current image ROI to the specified rectangle of the destination DC */

   virtual void  DrawToHDC( HDC hDCDst, RECT* pDstRect );

}

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：
