MFC多文档中opencv处理图像打开 保存

               

需要在C**Doc和C**View中进行相应修改

图像打开：

Doc.cpp中：

BOOL CCVMFCDoc::Load(IplImage** pp, LPCTSTR csFilename){ IplImage* pImg=NULL; pImg = cvLoadImage(csFilename,-1);      //  读图像文件(DSCV) if (!pImg) return(false); cvFlip(pImg);                           //  与 DIB 像素结构一致 if (*pp) {  cvReleaseImage(pp); } (*pp)=pImg; m_Display=0; return(true);}

BOOL CCVMFCDoc::OnOpenDocument(LPCTSTR lpszPathName){ if(!CDocument::OnOpenDocument(lpszPathName)) return false; Load(&pImg,lpszPathName); if(pImg) return true; return false;}

图像保存：

1.Doc.cpp中

BOOL CCVMFCDoc::Save(LPCTSTR csFilename, IplImage* pImg){ int   bl; cvFlip(pImg);                           //  恢复原 OpenCV 位图结构 bl=cvSaveImage(csFilename,pImg);        //  图像存盘 return(bl);}

2.View.cpp中

void CCVMFCView::OnFileSaveAs()//图像保存{ CFileDialog dlg(false,"*.bmp","Test.bmp",OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT,"保存为(*.bmp)|*.bmp|所有文件(*.*)|*.*||"); CString strPath(""); if(dlg.DoModal()==IDOK) {  cvFlip(workImg);  strPath=dlg.GetPathName();  cvSaveImage(strPath,workImg);  cvFlip(workImg); }}

整体代码如下：
