| 61 | <p><i>libtiff</i> supports a variety of compression schemes
|
|---|
| 62 | implemented by software <i>codecs</i>. Each codec adheres to
|
|---|
| 63 | a modular interface that provides for the decoding and
|
|---|
| 64 | encoding of image data; as well as some other methods for
|
|---|
| 65 | initialization, setup, cleanup, and the control of default
|
|---|
| 66 | strip and tile sizes. Codecs are identified by the
|
|---|
| 67 | associated value of the <small>TIFF</small>
|
|---|
| 68 | <i>Compression</i> tag; e.g. 5 for <small>LZW</small>
|
|---|
| 69 | compression.</p>
|

|
|---|
| 71 | <p>The <i>TIFFRegisterCODEC</i> routine can be used to
|
|---|
| 72 | augment or override the set of codecs available to an
|
|---|
| 73 | application. If the specified <i>scheme</i> already has a
|
|---|
| 74 | registered codec then it is <i>overridden</i> and any images
|
|---|
| 75 | with data encoded with this compression scheme will be
|
|---|
| 76 | decoded using the supplied coded.</p>
|
|---|
| 77 | <!-- INDENTATION -->
|
|---|
| 78 | <p><i>TIFFIsCODECConfigured</i> returns 1 if the codec is
|
|---|
| 79 | configured and working. Otherwise 0 will be returned.</p>
