An Image (GIF, JPEG, BMP, ICO, WMF and EMF) Viewer

Posted by chensu chensu on October 10th, 2002
ImgViewer

Environment: Visual C++ 6.0 with Service Pack 3, Windows 9x, Windows NT 4.0 with Service Pack 6a and Windows 2000

This sample is an MFC application using the document/view architecture that can load, display, and print graphics files such aske GIF, JPEG, BMP (bitmap), ICO (icon), WMF (metafile), and EMF (Win32-enhanced metafile). It shows:

  • how to use the OleLoadPicturePath function and the IPicture interface to load and display those graphics files.

    • (Look into the ImgViewerDoc.cpp, ImgViewerView.cpp, and MainFrm.cpp files.)
  • how to support more than one file extension per MFC document type.

    • (Look into the MulExtDocTmp.cpp, MulExtDocTmp.h, and ImgViewer.cpp files.)

Q218972How To Load and Display Graphics Files w/LOADPIC.EXE
(Note that LOADPIC.EXE does not handle palettes. As a result, it won't display a 256-color image correctly in 256-color mode. Also, it uses the OleLoadPicture function instead of the OleLoadPicturePath function.)

  • How to load and display bitmap files on a dialog box by MFC

    I want to make a little program that can show all the bitmaps in a specific directory, like a photo browsing software.

    But i don't know how to do it. I just know how to open a file dialog box to choose the folder only. I don't know how to display a bitmap file on a static control(Frame control).
    and i don't know how to create it dainamically, as i don't know there are how many pictures in the folder.

    Can you send me the project and teach me how to do so?
    Thanks alot !!

    Have a nice day

    • Display a bitmap on dialog box

      Posted by lavanya_thanneru on 01/19/2006 04:40am 

      I know how to display the bmp file on dialog box .But i have never displayed it on a static control.If u want to display a bmp on a static control then use Create() method of a CStatic  object this way...
CStatic st;
st.Creat(NULL,WS_CHILD|WS_VISIBLE|SS_BITMAP,CRect(10,10,400,400),this);

//Code to display the bmp
//szFileName is the name of bmp file
HBITMAP hBmp = (HBITMAP)::LoadImage(NULL,szFilename,IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
	
   CBitmap bmp;
   bmp.Attach(hBmp);
   
   CClientDC dc(this);
   CDC bmDC;
   bmDC.CreateCompatibleDC(&dc);
   CBitmap *pOldbmp = bmDC.SelectObject(&bmp);

   BITMAP  bi;
   bmp.GetBitmap(&bi);
   
   dc.BitBlt(0,0,bi.bmWidth,bi.bmHeight,&bmDC,0,0,SRCCOPY);

   bmDC.SelectObject(pOldbmp);

   ::DeleteDC(bmDC);
   ::DeleteObject(pOldbmp);

  • A very simple way to fix to the assertion failure under win98

    First i would to thank warmly Chen Su for his great code.

    It is very easy to get rid of the assertion failure when compiling the project under win98.

    Just change the project settings from Win32 Unicode Debug to Win32 Debug.

    That's all !
