/*bmp文件的前部是文件头信息,aboot中画图不需要这些
* 1 删除文件头信息,
*
* 以 24bit bmp: 134X290 为例
* 图片每一行134个像素,每个像素3个字节,所以每一行是134*3 == 402个字节,
* bmp会在每一行的最后添加两个字节对齐。
* aboot中要用这个图片的话,
* 2.要把每行最后的两个对齐字节删除
*
* 每行最后的两个字节删除以后
* 因为bmp本身的图片是倒的,
* 3.反转整张图
*
* 反转整张图以后,R和B也互换了,导致颜色不对
* R、G、B各占一个字节,
* 4.这里是使其中的R 和 B互换。
*
* 所以,如果把拿到手的图片先在windows上做一下180度的旋转,
* 应该可以省略步骤3和4,把上面的 REVERT_BMP 设定为0 即可。
