pallini..thnx..but i need a full running code for comparing 2 bitmaps.. i have posted my code but i cant understand what is wrong in my code... can you help please.. 1. void CPixelView::OnDraw(CDC* pDC) { CPixelDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); // TODO: add draw code for native data here { COLORREF color[255][255],color1[255][255]; CBitmap bitmap,bitmap1; CString file1,file2,strText; file1.Format("C:\\1.bmp"); file2.Format("C:\\3.bmp"); CDC dcMemory,dcMemory1; int r[255][255],R[255][255]; // 1st image HBITMAP hBitmap1 = (HBITMAP)::LoadImage(NULL,file1,IMAGE_BITMAP, 0, 0,LR_LOADFROMFILE );//| LR_CREATEDIBSECTION); //2nd image HBITMAP hBitmap2 = (HBITMAP)::LoadImage(NULL,file2,IMAGE_BITMAP, 0, 0,LR_LOADFROMFILE ); // Attach the loaded image to the CBitmap object. bitmap.Attach(hBitmap1); bitmap1.Attach(hBitmap2); dcMemory.CreateCompatibleDC(pDC); dcMemory.SelectObject(&bitmap); dcMemory1.CreateCompatibleDC(pDC); dcMemory1.SelectObject(&bitmap1); pDC->BitBlt(0,0,200,200,&dcMemory,0,0,SRCCOPY); pDC->BitBlt(0,0,300,700,&dcMemory1,0,0,SRCCOPY); //for all the pixels for(int i=0;i<48;i++) { for(int j=0;j<48;j++) { HDC hDC = ::GetDC(this->GetSafeHwnd()); color[i][j] = ::GetPixel(hDC,i,j); ::ReleaseDC(this->GetSafeHwnd(), hDC); r[i][j]=GetRValue(color[i][j]); HDC hDC1 = ::GetDC(this->GetSafeHwnd()); color1[i][j] = ::GetPixel(hDC1,i,j); ::ReleaseDC(this->GetSafeHwnd(), hDC1); R[i][j]=GetRValue(color1[i][j]); } }//got the pixel values } }
Well, you're "getting there"; Me thing you do not need to keep arrays of COLORREF or the r and R arrays You should be able to get the size of the bitmaps dynamically (because a bitmap of 48 pixel is really small) No need to get the DC twice. Now that you have the color for the same pixel position in both bitmaps; what should you be doing with them ? compare them ? maybe ?

Of course you can use of CImage class for read your bitmap files and like your code you can use of two loop(See CImage::GetPixel) I think its easy than your code.

thank you for the reply. can you tell how to make changes in the code. I am studying VC++ so not too much knowledge about the language.So can you help me with the code. Yes i am comparing both bitmap for checking whether both images are same or different. Thank You kaushal kishore Sharma kaushal..

:laugh: And can we use of this code for other formats like jpg? :laugh:

Nope. You have to change it:
if ( jpegImage1 == jpegImage2) ...
