45 * to pass tag types and values uses the types defined in
46 * tiff.h directly.
47 *
48 * NB: ttag_t is unsigned int and not unsigned short because
49 * ANSI C requires that the type before the ellipsis be a
50 * promoted type (i.e. one of int, unsigned int, pointer,
51 * or double) and because we defined pseudo-tags that are
52 * outside the range of legal Aldus-assigned tags.
53 * NB: tsize_t is signed and not unsigned because some functions
54 * return -1.
55 * NB: toff_t is not off_t for many reasons; TIFFs max out at
56 * 32-bit file offsets, and BigTIFF maxes out at 64-bit
57 * offsets being the most important, and to ensure use of
58 * a consistently unsigned type across architectures.
59 * Prior to libtiff 4.0, this was an unsigned 32 bit type.
