  3. Member Function in CvvImage Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  4. CvvImage in MFC • Select Multiple Documents • include in “StdAfx.h” #include <cv.h> • #include <cxcore.h> • #include <highgui.h> • #include <cvcam.h> • Add Member Variables • CvvImage m_cvvImage • char* m_szPathName Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  5. CvvImage in MFC • Add Virtual Function in Doc • Doc::OnOpenDocument(LPCTSTR lpszPathName) • { • if (!CDocument::OnOpenDocument(lpszPathName)) • return FALSE; • // TODO: Add your specialized creation code here • m_cvvImage.Load(lpszPathName); • m_szPathName=(char*)calloc(512,sizeof(char)); • strcpy(m_szPathName, (char*)lpszPathName); • return TRUE; • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  6. CvvImage in MFC • Add Virtual Function in Doc • Doc::DeleteContents() • { • // TODO: Add your specialized code here and/or call the base class • if(m_cvvImage.GetImage()!=NULL) • { • m_cvvImage.~CvvImage(); • } • CDocument::DeleteContents(); • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  7. CvvImage in MFC • Add Function in App • App::OnFileOpen() • { • // TODO: Add your command handler code here • char szFilter[]="JPEG file(*.jpeg, *.jpg, *,jpe) • | *.jpeg; *.jpg;, *.jpe|\ • Portable Network Graphics file(*.png)|*.png|\ • Windows bitmap files(*.bmp, *.dib)|*.bmp; *.dib|\ • Sun rasters(*.sr, *.ras)|*.sr; *.ras|\ • TIFF files(*.tiff, *.tif)|*.tiff; *.tif|\ • 지원하는 모든 영상 파일| • *.jpeg; *.jpg; *.jpe; *.png; *.bmp; *.dib; *.sr; *.ras;\ • *.tiff; *.tif||"; • CFileDialogfileDlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT,szFilter); • intiReturn=fileDlg.DoModal(); • if(iReturn==IDOK) • { • POSITION pos=fileDlg.GetStartPosition(); • while(pos) • { • OpenDocumentFile • (fileDlg.GetNextPathName(pos)); • } • } • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  8. CvvImage in MFC • Add Virtual Function in View • View::OnInitialUpdate() • { • CTestDoc* pDoc = GetDocument(); • ASSERT_VALID(pDoc); • CScrollView::OnInitialUpdate(); • CSizesizeTotal; • // TODO: calculate the total size of this view • if(pDoc->m_cvvImage.GetImage()) • { • int height=pDoc->m_cvvImage.Height(); • int width=pDoc->m_cvvImage.Width(); • sizeTotal=CSize(width, height); • } • else • { • sizeTotal.cx = sizeTotal.cy = 100; • } • SetScrollSizes(MM_TEXT, sizeTotal); • ResizeParentToFit(TRUE); • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  9. CvvImage in MFC • Add Virtual Function in View • View::OnDraw(CDC* pDC) • { • CTestDoc* pDoc = GetDocument(); • ASSERT_VALID(pDoc); • // TODO: add draw code for native data here • if(pDoc->m_cvvImage.GetImage()) • { • int height=pDoc->m_cvvImage.Height(); • int width=pDoc->m_cvvImage.Width(); • CRect rect=CRect(0,0,width,height); • pDoc->m_cvvImage.DrawToHDC(pDC->GetSafeHdc(),&rect); • ResizeParentToFit(FALSE); • } • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  10. CvvImage in MFC • Add Virtual Function in View • View::OnDraw(CDC* pDC) • { • CTestDoc* pDoc = GetDocument(); • ASSERT_VALID(pDoc); • // TODO: add draw code for native data here • if(pDoc->m_cvvImage.GetImage()) • { • int height=pDoc->m_cvvImage.Height(); • int width=pDoc->m_cvvImage.Width(); • CRect rect=CRect(0,0,width,height); • pDoc->m_cvvImage.DrawToHDC(pDC->GetSafeHdc(),&rect); • ResizeParentToFit(TRUE); • } • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.

  11. CvvImage in MFC • Add Virtual Function in ViewApp • App::InitInstance() • { • : • : • if(cmdInfo.m_nShellCommand==CCommandLineInfo::FileNew) • { • cmdInfo.m_nShellCommand=CCommandLineInfo::FileNothing; • } • : • : • } Digital Image Processing, Kim Nam Woo, Dongseo Univ.
