C++ 读取bmp图片示例程序

功能: 读取bmp 代码示例: typedef struct _bmpsize { long bmpWidth;//位图宽，单位为象素LONG=long（有符号） long bmpHeight;//位图高，单位为象素LONG=long（有符号） unsigned short BitCount;//每个象素所占用的比特位WORD=unsigned short long BytesPerLine;//位图每行数据所占的字节数LONG=long（有符号） bool operator ==(_bmpsize bs) { if(bmpWidth==bs.bmpWidth && bmpHeight==bs.bmpHeight && BitCount==bs.BitCount /*&&BytesPerLine==bs.BytesPerLine*/) return true; else return false; } bool operator !=(_bmpsize bs) { return !(*this==bs); } }BMPSIZE, *LPBMPSIZE;//位图大小信息 cl ass scBmp { public: scBmp(); virtual ~scBmp(); BITMAPFILEHEADER GetBmpFileHeader() const {return m_bmfHeader;}; const char * GetFileName() const {return m_pFileName.GetDataPointer();} BITMAPINFO * GetBmpInfo() const {return (BITMAPINFO *)m_pbi.GetDataPointer();} BMPSIZE GetBmpSize() const {return m_bmpSize;} // scFdmtlType * GetPixels() {return &m_pixels;} scBYTE * GetPixels() {return &m_pixels;}
