TIFFFindCODEC,  TIFFRegisterCODEC,  TIFFUnRegisterCODEC  -
       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);
DESCRIPTION
       libtiff  supports  a variety of compression schemes imple
       mented by software codecs.  Each codec adheres to a  modu
       lar  interface that provides for the decoding and encoding
       of image data; as well as some other methods for  initial
       ization,  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 compres
       sion.
       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.
DIAGNOSTICS
       No space to register compression scheme %s.  TIFFRegister
       CODEC was unable to allocate memory for  the  data  struc
       tures needed to register a codec.
       Cannot remove compression scheme %s; not registered.  TIF
       FUnRegisterCODEC did not locate the specified codec in the
       table of registered compression schemes.
