[ELGIS] Fwd: [gdal-dev] Libtiff 4.0.0 Released

[Peter Hopfgartner]

I do think that this is of a certain interest to us.

Should we try to include this in ELGIS? Should we craete an libtiff4 
package that can be installed in parallel to the current package? Every 
package needing LibTIFF 4 must be recompiled, anyway.

Folks,

Of interest to many GeoTIFF and GDAL users, Bob Friesenhahn
has announced:

"""
At long last, libtiff 4.0.0 is finally released.  Libtiff 4.0.0 is the
successor to the libtiff 3.9.X release series.  It is intended to be
largely API compatible with the 3.9.X releases, but it is definitely
not ABI compatible so any software which plans to use it will need to
be recompiled.  With appropriate care, source code can easily compile
with both the 3.9.X releases and libtiff 4.0.0.

This release supports the BigTIFF TIFF format in which all offsets are
unsigned 64-bit, supporting huge files.  APIs which deal with tag
offsets are necessarily updated to pass 64-bit values.  I/O functions
supporting the TIFFClientOpen() interface are updated to pass 64-bit
offset values.

Please visit the libtiff page at http://www.remotesensing.org/libtiff/
to learn more about the release, or to download it.
""""

Note that GDAL's internal version of libtiff has tracked libtiff4 for several
years, and it is substantially preferred to using libtiff 3.9 which
lacks bigtiff
and many fixes of value to GDAL.  Libgeotiff should work smoothly with
libtiff 3.9.x or libtiff 4.0.

Best regards,
