This type of image has Coding
set to IM_CODING_NONE
. The
header is then followed by a large array of pixels, laid out left-to-right,
top-to-bottom. Each pixel contains the specified number of bands. Each band
has the specified band format, which may be an 8-, 16- or 32-bit integer
(either signed or unsigned), a single or double precision IEEE floating
point number, or a pair of single or double precision floats forming a
complex number.
All values are stored in the host-machine's native number representation (that is, either most-significant first, as in SPARC and 680x0 machines, or least-significant first, for Intel and DEC machines). The VIPS library will automatically byte-swap for you if necessary, but this can be slow.
