Description: CImage类
CImage是MFC和ATL共享的新类，它能从外部磁盘中调入一个JPEG、GIF、BMP和PNG格式的图像文件加以显示，而且这些文件格式可以相互转换。由于CImage在不同的Windows操作系统中其某些性能是不一样的，因此在使用时要特别注意。例如，CImage::PlgBlt和CImage::MaskBlt只能在 Windows NT 4.0 或更高版本中使用，但不能运行在Windows 95/98 应用程序中。CImage::AlphaBlend和CImage::TransparentBlt也只能在 Windows 2000/98或其更高版本中使用。即使在Windows 2000运行程序还必须将stdafx.h文件中的WINVER和_WIN32_WINNT的预定义修改成0x0500才能正常使用。-CImage class CImage MFC and ATL is a new class of share, it transferred from the external disk in a JPEG, GIF, BMP, and PNG image file format to be displayed, and these file formats are interchangeable. As CImage Windows operating systems in different some of its properties are different, so special attention when in use.
