MFC多文件中opencv處理影象開啟、儲存
阿新 • • 發佈：2019-01-01
需要在C**Doc和C**View中進行相應修改
影象開啟：
Doc.cpp中：
BOOL CCVMFCDoc::Load(IplImage** pp, LPCTSTR csFilename) { IplImage* pImg=NULL; pImg = cvLoadImage(csFilename,-1); // 讀影象檔案(DSCV) if (!pImg) return(false); cvFlip(pImg); // 與 DIB 畫素結構一致 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;
}影象儲存：
1.Doc.cpp中
BOOL CCVMFCDoc::Save(LPCTSTR csFilename, IplImage* pImg) { int bl; cvFlip(pImg); // 恢復原 OpenCV 點陣圖結構 bl=cvSaveImage(csFilename,pImg); // 影象存檔 return(bl); }
2.View.cpp中
void CCVMFCView::OnFileSaveAs()//影象儲存 { CFileDialog dlg(false,"*.bmp","Test.bmp",OFN_HIDEREADONLY |OFN_OVERWRITEPROMPT,"儲存為(*.bmp)|*.bmp|所有檔案(*.*)|*.*||"); CString strPath(""); if(dlg.DoModal()==IDOK) { cvFlip(workImg); strPath=dlg.GetPathName(); cvSaveImage(strPath,workImg); cvFlip(workImg); } }
整體程式碼如下：
