The first 10 bytes can have two different meanings, depending on the fact whether the picture is standalone or an embedded object. Everything in it is counted in dots.
The magnification factors determine whether the picture should be compressed or expanded. 03E8 (1000 decimal) is normal size; lower numbers compress, higher numbers expand. So 01F4 would mean halfsize.
The cuts determine whether a portion of the picture should be hidden, on one of its four sides. Cuts are in fractions of C*Size. So 0000 means do no cut, and 0600 would hide half of a picture 0100 dots large.
