NAME

TIFFcodec - codec-related utility routines

SYNOPSIS

#include <tiffio.h>

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:

Cannot remove compression scheme %s; not registered:
