<i>libtiff</i> supports a variety of compression schemes
implemented by software <i>codecs</i>. 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 <small>TIFF</small>
<i>Compression</i> tag; e.g. 5 for <small>LZW</small>
compression.</td></table>

The <i>TIFFRegisterCODEC</i> routine can be used to augment
or override the set of codecs available to an application.
If the specified <i>scheme</i> already has a registered
codec then it is <i>overridden</i> and any images with data
encoded with this compression scheme will be decoded using
the supplied coded.</td></table>

<i>TIFFIsCODECConfigured</i> returns 1 if the codec is
configured and working. Otherwise 0 will be
returned.</td></table>
