NAME
libtiff - introduction to libtiff, a library for reading and writing TIFF files
SYNOPSIS
#include <tiffio.h>
cc file.c -ltiff
DESCRIPTION
libtiff is a library for reading and writing data files encoded with the "Tag Image File" format,
Revision 6.0 (or revision 5.0 or revision 4.0). This file format is suitable for archiving multi-color
and monochromatic image data.
The library supports several compression algorithms, as indicated by the Compression field, including: no
compression (1), CCITT 1D Huffman compression (2), CCITT Group 3 Facsimile compression (3), CCITT Group 4
Facsimile compression (4), Lempel-Ziv & Welch compression (5), baseline JPEG compression (7),
word-aligned 1D Huffman compression (32771), PackBits compression (32773). In addition, several
nonstandard compression algorithms are supported: the 4-bit compression algorithm used by the ThunderScan
program (32809) (decompression only), NeXT's 2-bit compression algorithm (32766) (decompression only), an
experimental LZ-style algorithm known as Deflate (32946), and an experimental CIE LogLuv compression
scheme designed for images with high dynamic range (32845 for LogL and 32845 for LogLuv). Directory
information may be in either little- or big-endian byte order; byte swapping is automatically done by the
library. Data bit ordering may be either Most Significant Bit (MSB) to Least Significant Bit (LSB) or LSB
to MSB. Finally, the library does not support files in which the BitsPerSample , Compression ,
MinSampleValue , or MaxSampleValue fields are defined differently on a per-sample basis (in Rev. 6.0 the
Compression tag is not defined on a per-sample basis, so this is immaterial).
DATA TYPES
The library makes extensive use of C typedefs to promote portability. Two sets of typedefs are used, one
for communication with clients of the library and one for internal data structures and parsing of the
TIFF format. The following typedefs are exposed to users either through function definitions or through
parameters passed through the varargs interfaces.
typedef uint32_t ttag_t; // directory tag
typedef uint32_t tdir_t; // directory index
typedef uint16_t tsample_t; // sample number
typedef uint32_t tstrip_t; // strip number
typedef uint32_t ttile_t; // tile number
typedef int64_t tmsize_t; // signed size type (int32_t on 32-bit platforms)
typedef tmsize_t tsize_t; // i/o size in bytes
typedef void* tdata_t; // image data ref
typedef void* thandle_t; // client data handle
typedef uint64_t toff_t; // file offset
Note that tstrip_t, ttile_t, and tsize_t are constrained to be no more than 32-bit quantities by 32-bit
fields they are stored in in the TIFF image. Likewise tsample_t is limited by the 16-bit field used to
store the SamplesPerPixel tag.
tdir_t constrains the maximum number of IFDs that may appear in an image and may be an arbitrary size
(w/o penalty). Starting with libtiff 4.5.0, tdir_t is a 32-bit unsigned integer. Previously, it was a
16-bit unsigned integer.
ttag_t must be either int, unsigned int, pointer, or double because the library uses a varargs interface
and C restricts the type of the parameter before an ellipsis to be a promoted type. toff_t is defined as
uint64_t because TIFF file offsets are (unsigned) 32-bit quantities, and BigTIFF file offsets are
unsigned 64-bit quantities. A signed value is used because some interfaces return -1 on error. Finally,
note that user-specified data references are passed as opaque handles and only cast at the lowest layers
where their type is presumed.

stderr in the form: module: message\n. Warning messages are likewise directed through the
TIFFWarningExtR() routine.
