 * tiff.h directly.
 *
 * NB: ttag_t is unsigned int and not unsigned short because
 *     ANSI C requires that the type before the ellipsis be a
 *     promoted type (i.e. one of int, unsigned int, pointer,
 *     or double) and because we defined pseudo-tags that are
 *     outside the range of legal Aldus-assigned tags.
 * NB: tsize_t is int32 and not uint32 because some functions
 *     return -1.
 * NB: toff_t is not off_t for many reasons; TIFFs max out at
 *     32-bit file offsets being the most important, and to ensure
 *     that it is unsigned, rather than signed.

Summary ✨

This is a C++ header file that provides an interface for working with TIFF (Tagged Image File Format) images. It defines functions and data types for reading, writing, and manipulating TIFF files, including image processing and color conversion operations. The code appears to be part of a larger library or framework for image processing and manipulation.
