<h1>Extending LibTiff library with support for the new BigTIFF format</h1>
|
||||
<p>
|
||||
<a href="http://www.remotesensing.org/libtiff/">LibTiff</a> maintainers have started work on LibTiff 4.0,
|
||||
the next major upgrade of the time-proven <a href="http://www.awaresystems.be/imaging/tiff.html">TIFF</a>
|
||||
codec. This upgrade will include support for the new BigTIFF file format. It is planned a preliminary
|
||||
version (LibTiff 4.0alpha1) will be operational by June 15, 2007. Testing and final release improvements
|
||||
for LibTiff 4.0 will be completed by July 30, 2007.
|
||||
</p>
|
||||
<p>
|
||||
BigTIFF logically extends the original TIFF file format (referred to as 'ClassicTIFF' from now on),
|
||||
breaking the 4 gigabyte boundary, with 64bit offsets allowing files up to 18,000 petabytes in size. The
|
||||
BigTIFF specification is the result of work by a variety of parties on the LibTiff mailing list, including
|
||||
the current LibTiff maintainers, Joris Van Damme and Adobe staff. The BigTIFF specification has not yet
|
||||
been officially approved by the TIFF specification owner (Adobe), but implementation within LibTiff
|
||||
could accelerate that process. For more information on the BigTIFF file format, we recommend AWare Systems'
|
||||
<a href="http://www.awaresystems.be/imaging/tiff/bigtiff.html">BigTIFF page</a>.
|
||||
</p>
|
||||
<p>
|
||||
BigTIFF will be especially useful for people and vendors that are confronted with very large images, and
|
||||
still seek to use an open, simple, and extendable format. This requirement is frequently encountered in the
|
||||
geospatial field, but also concerns large format scanners, medical imaging and other fields.
|
||||
</p>
|
||||
<p>
|
||||
The LibTiff BigTIFF upgrade is made possible by four sponsors funding the project. The programming work will
|
||||
primarily be done by <a href="http://www.awaresystems.be/index.html">Joris Van Damme (AWare Systems)</a>.
|
||||
LibTiff's licensing agreement will remain unchanged. More details on the project itself, are available from
|
||||
the <a href="http://www.remotesensing.org/libtiff/BigTIFFProposal.html">BigTIFF in LibTiff project page</a>.
