TIFFcodec(3tiff)					 Introduction to Library Functions					  TIFFcodec(3tiff)

NAME

       TIFFcodec, 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 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, for example, 5 for LZW compression.

EXTENDED DESCRIPTION

       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, the registered codec is overridden and any images with  data  encoded  with  this  compression  scheme  are
       decoded using the supplied codec.

   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.
