libtiff 4.0.0 Alpha

libtiff project provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.
Included in this software distribution is a library, libtiff, for reading and writing TIFF, a small collection of tools for doing simple manipulations of TIFF images, and documentation on the library and tools. Libtiff is a portable software, it was built and tested on various systems: UNIX flavors (Linux, BSD, Solaris, MacOS X), Windows, OpenVMS. It should be possible to port libtiff and additional tools on other OSes.
The library, along with associated tool programs, should handle most of your needs for reading and writing TIFF images on 32- and 64-bit machines. This software can also be used on older 16-bit systems though it may require some effort and you may need to leave out some of the compression support.
The software was originally authored and maintained by Sam Leffler. While he keeps a fatherly eye on the mailing list, he is no longer responsible for day to day maintenance.
Enhancements:
- The BigTIFF specification is now supported, allowing the creation of files larger than 4GiB.
- Despite this large upgrade, the library remains almost completely source compatible with the previous releases and in most cases you just need to recompile your application with new library to get read support for BigTIFF.
