NAME


TIFFcodec - codec-related utility routines

SYNOPSIS



#include <tiffio.h>

const TIFFCodec *TIFFFindCODEC(uint16_t scheme)

TIFFCodec *TIFFRegisterCODEC(uint16_t scheme, const char *method,
TIFFInitMethod init)

void TIFFUnRegisterCODEC(TIFFCodec *codec)

int TIFFIsCODECConfigured(uint16_t scheme)

TIFFCodec *TIFFGetConfiguredCODECs(uint16_t scheme)

int TIFFSetCompressionScheme(TIFF *tif, int scheme)

DESCRIPTION


libtiff supports a variety of compression schemes implemented by
software codecs. Each codec adheres to a modular interface that
provides for the decoding and encoding of image data; as well as some
other methods for initialization, setup, cleanup, and the control of
default strip and tile sizes. Codecs are identified by the
associated value of the TIFF Compression tag; e.g. 5 for LZW
compression.

TIFFFindCODEC() ??????

TIFFUnRegisterCODEC() ?????

The TIFFRegisterCODEC() routine can be used to augment or override
the set of codecs available to an application. If the specified
scheme already has a registered codec then it is overridden and any
images with data encoded with this compression scheme will be decoded
using the supplied codec.

TIFFIsCODECConfigured() returns 1 if the codec is configured and
working. Otherwise 0 will be returned.

TIFFGetConfiguredCODECs() gets list of configured codecs, both
built-in and registered by user. Function returns array of TIFFCodec
records (the last record should be NULL) or NULL if function failed.
Caller is responsible to free this structure.

TIFFSetCompressionScheme() ????

DIAGNOSTICS


No space to register compression scheme %s:
TIFFRegisterCODEC() was unable to allocate memory for the data
structures needed to register a codec.

Cannot remove compression scheme %s; not registered:
TIFFUnRegisterCODEC() did not locate the specified codec in the
table of registered compression schemes.
