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：

[cpp] ​​view plain​​​ ​​copy​​

1. 1. 
      
2. BOOL CCVMFCDoc::Load(IplImage** pp, LPCTSTR csFilename)
3. {
4. IplImage* pImg=NULL;
5. 
   
6. pImg = cvLoadImage(csFilename,-1); // 读图像文件(DSCV)
7. if (!pImg) return(false);
8. cvFlip(pImg); // 与 DIB 像素结构一致
9. if (*pp) {
10. cvReleaseImage(pp);
11. }
12. (*pp)=pImg;
13. m_Display=0;
14. return(true);
15. }
    1. 
       

[cpp] ​​view plain​​​ ​​copy​​

1. 1. 
      
2. BOOL CCVMFCDoc::OnOpenDocument(LPCTSTR lpszPathName)
3. {
4. if(!CDocument::OnOpenDocument(lpszPathName)) return false;
5. Load(&pImg,lpszPathName);
6. if(pImg) return true;
7. return false;
8. }
   1. 
      

图像保存：

1.Doc.cpp中

[cpp] ​​view plain​​​ ​​copy​​

1. 1. 
      
2. BOOL CCVMFCDoc::Save(LPCTSTR csFilename, IplImage* pImg)
3. {
4. int bl;
5. cvFlip(pImg); // 恢复原 OpenCV 位图结构
6. bl=cvSaveImage(csFilename,pImg); // 图像存盘
7. return(bl);
8. }
   1. 
      

2.View.cpp中

[cpp] ​​view plain​​​ ​​copy​​

1. 1. 
      
2. void CCVMFCView::OnFileSaveAs()//图像保存
3. {
4. CFileDialog dlg(false,"*.bmp","Test.bmp",OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT,"保存为(*.bmp)|*.bmp|所有文件(*.*)|*.*||");
5. CString strPath("");
6. if(dlg.DoModal()==IDOK)
7. {
8. cvFlip(workImg);
9. strPath=dlg.GetPathName();
10. cvSaveImage(strPath,workImg);
11. cvFlip(workImg);
12. }
13. }
    1. 
       

整体代码如下：
