It took several hours to read the format of the BMP file and write a small program... BMP file format written good article: http://www.cnblogs.com/ZXYloveFR/archive/2012/08/06/2625225.html BMP file format: typedef struct tagBITMA

BMP format uses a small-end way to store data, the structure of the file header in order as follows:Two bytes: ‘BM‘ represents a Windows Bitmap, ‘BA‘ represents a OS/2 bitmap, a 4-byte integer: Represents the bitmap size, a 4-byte integer: Reserved bit, always 0, and a 4-byte integer: The actual image offset; a 4-byte integer: The number of bytes in the header; A 4-byte integer: Image width; a 4-byte intege

A bmp file consists of four parts: File Header, bitmap information header, color information, and image data: Bitmapfileheader Bitmapinfoheader Bitmap color table rgbquad Bitmap pixel data 1. Bitmap File Header The bitmap file header
