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.
