- Header.
- A header usually starts with some sort of unique identification value called a file identifier, file ID, or ID value. ...

- Following the identification value in the header is usually a field containing the file version. Naturally enough, successive versions of bitmap formats may differ in characteristics such as header size, bitmap data supported, and color capability. ...
- If the format supports some sort of encoding designed to reduce the size of the bitmap data, then a compression type field will be found in the header. ...

This field may contain 7-bit ASCII data, for portability of the header information across platforms. ...
- At the end of the header may be an unused field, sometimes referred to as padding, filler, reserved space, or reserved fields. ... All we know about them are their sizes and positions in the header. ...
