Here bmfh is an object of BITMAPFILEHEADER and I am not sure to achieve the core meaning of the statement below can U explain me ? if(bmfh.bfType != 0x4d42) { throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹‚Å‚Í‚ ‚è‚Ü‚¹‚ñ"); }

I have a sample project and I have to implement this code into my project. I could not understand the theme of the code can you make me understand the code? The code goes like this void CDib::BmpLoad(CFile& rBmpFile) { int nCount, nSize; BITMAPFILEHEADER bmfh; nCount = rBmpFile.Read((LPVOID) &bmfh, sizeof(BITMAPFILEHEADER)); if(nCount != sizeof(BITMAPFILEHEADER)) { throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹ƒTƒCƒY‚ªˆÙí‚Å‚·"); } // ƒtƒ@ƒCƒ‹ƒwƒbƒ_‚Ì'BM'‚ðŠm”F if(bmfh.bfType != 0x4d42) { throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹‚Å‚Í‚ ‚è‚Ü‚¹‚ñ"); } nSize = bmfh.bfOffBits - sizeof(BITMAPFILEHEADER); m_pBmpHead = (LPBITMAPINFOHEADER) new BYTE[nSize]; nCount = rBmpFile.Read(m_pBmpHead, nSize); // info hdr & color table this->ComputeMetrics(); // BOOL ret; // m_pImage = (LPBYTE)VirtualAlloc(NULL,m_dwSizeImage,MEM_RESERVE|MEM_COMMIT,PAGE_READWRITE); // if(m_pImage == NULL) // VirtualAlloc(&m_pImage,m_dwSizeImage,MEM_COMMIT,PAGE_READWRITE); // MEMORY_BASIC_INFORMATION MemoryBasicInfo; // VirtualQuery(m_pImage,&MemoryBasicInfo,sizeof(MemoryBasicInfo)); // if(MemoryBasicInfo.State != MEM_COMMIT) // return; // ret =VirtualLock((LPVOID)m_pImage,m_dwSizeImage); m_pImage = (LPBYTE) new BYTE[m_dwSizeImage]; nCount = rBmpFile.Read(m_pImage, m_dwSizeImage); // image only // ret =VirtualUnlock((LPVOID)m_pImage,m_dwSizeImage); this->ComputePaletteSize(m_pBmpHead->biBitCount); this->MakePalette(); this->MakeDDB(); }
