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), and 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 unsigned short uint16;

-
- -

16-bit unsigned integer

-
- -

typedef unsigned <thing> -uint32;

-
- -

32-bit unsigned integer

-
- -

typedef unsigned int ttag_t;

-
- -

directory tag

-
- -

typedef uint16 tdir_t;

-
- -

directory index

-
- -

typedef uint16 tsample_t;

-
- -

sample number

-
- -

typedef uint32 tstrip_t;

-
- -

strip number

-
- -

typedef uint32 ttile_t;

-
- -

tile number

-
- -

typedef int32 tsize_t;

-
- -

i/o size in bytes

-
- -

typedef void* tdata_t;

-
- -

image data ref

-
- -

typedef void* thandle_t;

-
- -

client data handle

-
- -

typedef int32 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). ttag_t must be either int, -unsigned int, pointer, or double because the library uses a -varargs interface and ANSI C restricts the type -of the parameter before an ellipsis to be a promoted type. -toff_t is defined as int32 because TIFF file offsets -are (unsigned) 32-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.

-
- -

LIST OF ROUTINES

- - - - - -
-

The following routines are part of the library. -Consult specific manual pages for details on their -operation; on most systems doing ‘‘man -function-name’’ will work.

TAG USAGE

- - - - - -
-

The table below lists the TIFF tags that -are recognized and handled by the library. If no use is -indicated in the table, then the library reads and writes -the tag, but does not use it internally. Note that some tags -are meaningful only when a particular compression scheme is -being used; e.g. Group3Options is only useful if -Compression is set to CCITT Group 3 -encoding. Tags of this sort are considered -codec-specific tags and the library does not -recognize them except when the Compression tag has -been previously set to the relevant compression -scheme.

PSEUDO TAGS

- - - - - -
-

In addition to the normal TIFF tags the -library supports a collection of tags whose values lie in a -range outside the valid range of TIFF tags. These -tags are termed pseud-tags and are used to control -various codec-specific functions within the library. The -table below summarizes the defined pseudo-tags.

TIFFTAG_FAXMODE

- - - - - -
-

Control the operation of the Group 3 codec. Possible -values (independent bits that can be combined by -or’ing them together) are: FAXMODE_CLASSIC (enable -old-style format in which the RTC is written at -the end of the last strip), FAXMODE_NORTC (opposite of -FAXMODE_CLASSIC; also called FAXMODE_CLASSF), FAXMODE_NOEOL -(do not write EOL codes at the start of each row -of data), FAXMODE_BYTEALIGN (align each encoded row to an -8-bit boundary), FAXMODE_WORDALIGN (align each encoded row -to an 16-bit boundary), The default value is dependent on -the compression scheme; this pseudo-tag is used by the -various G3 and G4 codecs to share code.

-
- - - - - -
-

TIFFTAG_FAXFILLFUNC

- - - - - -
-

Control the function used to convert arrays of black -and white runs to packed bit arrays. This hook can be used -to image decoded scanlines in multi-bit depth rasters (e.g. -for display in colormap mode) or for other purposes. The -default value is a pointer to a builtin function that images -packed bilevel data.

-
- - - - - -
-

TIFFTAG_IPTCNEWSPHOTO

- - - - - -
-

Tag contaings image metadata per the IPTC newsphoto -spec: Headline, captioning, credit, etc... Used by most wire -services.

-
- - - - - -
-

TIFFTAG_PHOTOSHOP

- - - - - -
-

Tag contains Photoshop captioning information and -metadata. Photoshop uses in parallel and redundantly -alongside IPTCNEWSPHOTO information.

-
- - - - - -
-

TIFFTAG_JPEGQUALITY

- - - - - -
-

Control the compression quality level used in the -baseline algorithm. Note that quality levels are in the -range 0-100 with a default value of 75.

-
- - - - - -
-

TIFFTAG_JPEGCOLORMODE

- - - - - -
-

Control whether or not conversion is done between -RGB and YCbCr colorspaces. Possible values are: -JPEGCOLORMODE_RAW (do not convert), and JPEGCOLORMODE_RGB -(convert to/from RGB) The default value is -JPEGCOLORMODE_RAW.

-
- - - - - -
-

TIFFTAG_JPEGTABLESMODE

- - - - - -
-

Control the information written in the -JPEGTables tag. Possible values (independent bits -that can be combined by or’ing them together) are: -JPEGTABLESMODE_QUANT (include quantization tables), and -JPEGTABLESMODE_HUFF (include Huffman encoding tables). The -default value is -JPEGTABLESMODE_QUANT|JPEGTABLESMODE_HUFF.

-
- - - - - -
-

TIFFTAG_ZIPQUALITY

- - - - - -
-

Control the compression technique used by the -Deflate codec. Quality levels are in the range 1-9 with -larger numbers yielding better compression at the cost of -more computation. The default quality level is 6 which -yields a good time-space tradeoff.

-
- - - - - -
-

TIFFTAG_PIXARLOGDATAFMT

- - - - - -
-

Control the format of user data passed in to -the PixarLog codec when encoding and passed out from -when decoding. Possible values are: PIXARLOGDATAFMT_8BIT for -8-bit unsigned pixels, PIXARLOGDATAFMT_8BITABGR for 8-bit -unsigned ABGR-ordered pixels, PIXARLOGDATAFMT_11BITLOG for -11-bit log-encoded raw data, PIXARLOGDATAFMT_12BITPICIO for -12-bit PICIO-compatible data, PIXARLOGDATAFMT_16BIT for -16-bit signed samples, and PIXARLOGDATAFMT_FLOAT for 32-bit -IEEE floating point samples.

-
- - - - - -
-

TIFFTAG_PIXARLOGQUALITY

- - - - - -
-

Control the compression technique used by the -PixarLog codec. This value is treated identically to -TIFFTAG_ZIPQUALITY; see the above description.

-
- - - - - -
-

TIFFTAG_SGILOGDATAFMT

- - - - - -
-

Control the format of client data passed in -to the SGILog codec when encoding and passed out from -when decoding. Possible values are: SGILOGDATAFMT_FLTXYZ for -converting between LogLuv and 32-bit IEEE floating valued -XYZ pixels, SGILOGDATAFMT_16BITLUV for 16-bit encoded Luv -pixels, SGILOGDATAFMT_32BITRAW and SGILOGDATAFMT_24BITRAW -for no conversion of data, SGILOGDATAFMT_8BITRGB for -returning 8-bit RGB data (valid only when decoding -LogLuv-encoded data), SGILOGDATAFMT_FLTY for converting -between LogL and 32-bit IEEE floating valued Y pixels, -SGILOGDATAFMT_16BITL for 16-bit encoded L pixels, and -SGILOGDATAFMT_8BITGRY for returning 8-bit greyscale data -(valid only when decoding LogL-encoded data).

-
- -

DIAGNOSTICS

- - - - - -
-

All error messages are directed through the -TIFFError routine. By default messages are directed -to stderr in the form: module: message\n. -Warning messages are likewise directed through the -TIFFWarning routine.

BUGS

- - - - - -
-

The library does not support multi-sample images -where some samples have different bits/sample.

- -

The library does not support random access to -compressed data that is organized with more than one row per -tile or strip.
