opencv图片右转函数

因为需要将函数进行右转，发现opencv自带 的过于麻烦。自己写了个右转的。可以根据这个想法写出任何方向的

 //函数功能，右转图片

 IplImage* convertImage(IplImage* image)

 {

     CvSize size = cvGetSize(image);

     IplImage* ori_image = cvCreateImage(cvSize(size.width / , size.height / ), image->depth, image->nChannels);

     IplImage* cvt_image = cvCreateImage(cvSize(size.height / , size.width / ), image->depth, image->nChannels);

     cvResize(image, ori_image);

     int x, y, w;

     for (y = ori_image->height; y >= ; y--)

     {

         uchar* oriptr = (uchar*)(ori_image->imageData + y*ori_image->widthStep);

         for (x = ; x < ori_image->width; x++)

         {

             uchar* curptr = (uchar*)(cvt_image->imageData + x*cvt_image->widthStep);

             curptr[ * y] = oriptr[ * x];

             curptr[ * y + ] = oriptr[ * x + ];

             curptr[ * y + ] = oriptr[ * x + ];

         }

     }

     cvReleaseImage(&image);

     cvReleaseImage(&ori_image);

     return cvt_image;

 }
