NAME

       TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC, TIFFIsCODECConfigured - codec-related utility routines

SYNOPSIS

       #include <tiffio.h>

       const TIFFCodec* TIFFFindCODEC(uint16 scheme);
       TIFFCodec* TIFFRegisterCODEC(uint16 scheme, const char *method, TIFFInitMethod init);
       void TIFFUnRegisterCODEC(TIFFCodec *codec);
       int TIFFIsCODECConfigured(uint16 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.

       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 coded.

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

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.
