MFC多文档中opencv处理图像打开、保存
2016-04-10 14:15 GarfieldEr007 阅读(1103) 评论(0) 编辑 收藏 举报需要在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);
- }
- }
