<p><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.</p>
|
|
<!-- INDENTATION -->
|
|
<p>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.</p>
