The 4 bytes that indicate data offset (which is where the color data will actually begin) | ||
The 4 bytes that indicate the size of the DIB header | ||
The 4 bytes that indicate the bitmap width | ||
The 4 bytes that indicate the bitmap height | ||
The 4 bytes that indicate the size of the DIB header | ||
