The BMP DIB header, which has multiple versions. The officially documented versions (BITMAPCOREHEADER, BITMAPINFOHEADER, BITMAPV4HEADER, BITMAPV5HEADER) can be found here, but there are also some undocumented versions see wikipedia.

Find out what version header is being used by accessing the size property of the DIB header (returns length of DIB header in bytes), since different versions of the DIB headers are all different lengths.

Depending on what DIB header version is being used (BITMAPV5HEADER is the most modern and common), fields that are Options may or may not exist.
