<H2>DESCRIPTION</H2>
|
|
|
|
<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
|
|
<FONT SIZE="-1">TIFF</FONT>
|
|
<I>Compression</I>
|
|
|
|
tag; e.g. 5 for
|
|
<FONT SIZE="-1">LZW</FONT>
|
|
compression.
|
|
<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.
