TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC, TIFFIsCODECConfigured - 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 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 codec.

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 codec.

"Cannot remove compression scheme %s; not registered" . TIFFUnRegisterCODEC did not locate the specified codec in the table of registered compression schemes.
