C++读入图片

给你一个，写的很不错
IPicture *m_picture;
OLE_XSIZE_HIMETRIC m_width;
OLE_YSIZE_HIMETRIC m_height;

CString m_filename("G:\\my photo\\照片和视频\\DSC_00516.jpg");//文件名

CFile m_file(m_filename,CFile::modeRead );

//获取文件长度
DWORD m_filelen = m_file.GetLength();

//在堆上分配空间
HGLOBAL m_hglobal = GlobalAlloc(GMEM_MOVEABLE,m_filelen);

LPVOID pvdata = NULL;
//锁定堆空间,获取指向堆空间的指针
pvdata = GlobalLock(m_hglobal);

//将文件数据读区到堆中
m_file.ReadHuge(pvdata,m_filelen);

IStream* m_stream;

GlobalUnlock(m_hglobal);

//在堆中创建流对象
CreateStreamOnHGlobal(m_hglobal,TRUE,&m_stream);

//利用流加载图像
OleLoadPicture(m_stream,m_filelen,TRUE,IID_IPicture,(LPVOID*)&m_picture);

m_picture->get_Width(&m_width);
m_picture->get_Height(&m_height);

CDC* dc = GetDC();

//m_IsShow = TRUE;
