The recently created farbfeld format is quite minimal, though there is not much software supporting it (at least so far).

Bytes                  │ Description
8                      │ "farbfeld" magic value
4                      │ 32-Bit BE unsigned integer (width)
4                      │ 32-Bit BE unsigned integer (height)
(2+2+2+2)*width*height │ 4*16-Bit BE unsigned integers [RGBA] / pixel, row-major
