NAME¶TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC, TIFFIsCODECConfigured - codec-related utility routines
const TIFFCodec* TIFFFindCODEC(uint16_t
TIFFCodec* TIFFRegisterCODEC(uint16_t scheme, const char *method, TIFFInitMethod init);
void TIFFUnRegisterCODEC(TIFFCodec *codec);
int TIFFIsCODECConfigured(uint16_t 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.
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.
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.
