       Configured - codec-related utility routines

       #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);

       libtiff	supports a variety of compression schemes implemented by soft‐
       ware 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.

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

       Cannot  remove  compression scheme %s; not registered.  TIFFUnRegister‐
       CODEC did not locate the specified codec in  the	 table	of  registered
       compression schemes.
