在不需要位图时，记得使用DeleteObject函数进行删除。在Windows CE中，cPlanes参数必须设置为1。关于版本兼容性，CreateBitmap在Windows NT 3.1及以上版本、Windows 95及以上版本，以及Windows CE 1.0及以上版本中可用。相关的头文件是wingdi.h，库文件是gdi32.lib。
至于 YUV 转 Bitmap 的话，可以网上找找 C 的库，性能比直接输出 JPEG 转 Bitmap 更高。接下来就是图像的方向和屏幕不一致了，网上搜索旋转 Bitmap ，基本上都是说使用 来创建一个新的 Bitmap ，然后将原 Bitmap 释放掉，这时候坑就来了，在平时这样使用是没事的，但是在相机预览输出的时候就...
