CvvImage类

时间:2022-01-08 14:53:14

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

/* 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 );
#endif
protected:
IplImage* m_img;
};
typedef CvvImage CImage;
#endif

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:
