Description: 旋转图像
如果你的应用程序仅工作在Windows NT下,那么你可以通过API函数旋转你的位图。
你或者使用world transformation和BitBlt()或者使用PlgBlt()旋转位图。一个
使用第一种方法的函数显示在下面。-rotating images if your applications only work on Windows NT, then you can use your API function rotating bitmap. You or the use of world transformation and BitBlt () or use Plg Blt () rotating bitmap. A first method is a function shown below.

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. For example, CImage:: PlgBlt and CImage:: MaskBlt only in Windows NT 4.0, or later use, but will not run on Windows 95/98 application. CImage:: AlphaBlend and CImage:: TransparentBlt only in Windows 2000/98 or later use. Even in the Windows 2000 operating procedures must also stdafx.h file WINVER and _WIN32_WINNT 0x0500 predefined modified to be used normally.

Description: 一个使用GDI实现的一个带有3D效果的旋转的立方体。(vs2008工程)
CDC::PlgBlt函数可以实现将资源设备中的一个方形区域映射到目标设备上的一个平行四边形区域中,而这个函数还提供了一个遮罩位图,利用这个功能再加上合适的计算可以实现将资源位图中的任意一个三角形区域映射到目标设备上的任意三角形区域。而这个功能正是3D绘图中最基本的“三角形贴图”。-GDI achieved using a 3D effect with a rotating cube. (Vs2008 projects)
CDC:: PlgBlt function device resources can be achieved in a square area on the map to the target device in the area of a parallelogram, and
This function also provides a mask bitmap using this function can be calculated together with the appropriate resources to achieve any of the bitmap in the three
Angular region mapped to the target device on any triangle. And this function is the most basic 3D graphics, "triangle map."
