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：

1. BOOL CCVMFCDoc::Load(IplImage** pp, LPCTSTR csFilename)
2. {
3. IplImage* pImg=NULL;
4. pImg = cvLoadImage(csFilename,-1);      //  读图像文件(DSCV)
5. if (!pImg) return(false);
6. cvFlip(pImg);                           //  与 DIB 像素结构一致
7. if (*pp) {
8. cvReleaseImage(pp);
9. }
10. (*pp)=pImg;
11. m_Display=0;
12. return(true);
13. }

1. BOOL CCVMFCDoc::OnOpenDocument(LPCTSTR lpszPathName)
2. {
3. if(!CDocument::OnOpenDocument(lpszPathName))    return false;
4. Load(&pImg,lpszPathName);
5. if(pImg) return true;
6. return false;
7. }

图像保存：

1.Doc.cpp中

1. BOOL CCVMFCDoc::Save(LPCTSTR csFilename, IplImage* pImg)
2. {
3. int   bl;
4. cvFlip(pImg);                           //  恢复原 OpenCV 位图结构
5. bl=cvSaveImage(csFilename,pImg);        //  图像存盘
6. return(bl);
7. }

2.View.cpp中

1. void CCVMFCView::OnFileSaveAs()//图像保存
2. {
3. CFileDialog dlg(false,"*.bmp","Test.bmp",OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT,"保存为(*.bmp)|*.bmp|所有文件(*.*)|*.*||");
4. CString strPath("");
5. if(dlg.DoModal()==IDOK)
6. {
7. cvFlip(workImg);
8. strPath=dlg.GetPathName();
9. cvSaveImage(strPath,workImg);
10. cvFlip(workImg);
11. }
12. }

整体代码如下：
