10139N/A<para><literal>libtiff</literal> supports a variety of compression schemes

10139N/Aimplemented by software codecs. Each codec adheres to a modular interface

10139N/Athat provides for the decoding and encoding of image data, as well as some

10139N/Aother methods for initialization, setup, cleanup, and the control of default

10139N/Astrip and tile sizes. Codecs are identified by the associated value of the

10139N/ATIFF Compression tag, for example, 5 for LZW compression.</para>
