+ LibTiff maintainers have started work on LibTiff 4.0, + the next major upgrade of the time-proven TIFF + 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. +
++ 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' + BigTIFF page. +
++ 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. +
++ The LibTiff BigTIFF upgrade is made possible by four sponsors funding the project. The programming work will + primarily be done by Joris Van Damme (AWare Systems). + LibTiff's licensing agreement will remain unchanged. More details on the project itself, are available from + the BigTIFF in LibTiff project page. +
