[gdal-dev] Support for GeoTIFF 12 bit with JPEG compression.

[Even Rouault]

Zoltan,

GDAL supports reading & writing JPEG-IN-TIFF 12bit since version 1.7.0, 
provided that you build it with internal libtiff and internal libjpeg.

See http://trac.osgeo.org/gdal/wiki/TIFF12BitJPEG

Best regards,

Even
