bmp类型的文件转换成yuv格式，这个代码是一个控制台程序，不是现成的对话框或者单文档，不过这个程序对理解转换过程是很好的。希望有能力的人也可以该机你下让它成为一个对话框或者单文档得形式的转换工具。-bmp file types into yuv format, the code is a console program, not a ready-made dialog box or a single document, but this procedure is a very good understanding of the conversion process. I hope those who can afford it you can make it into a dialog box, under a single document or a form of conversion tools.
