Roni,

This functionality is not part of libgeotiff.

Is the GeoTIFF in question in a geographic coordinate
system, or a projected coordinate system?  If it is in
geographic (lat/long) coordinates you could use a tool
such as gdal_translate to extract the window.

eg.
gdal_translate -projwin 20 -14 21 -15 in.tif out.tif

would extract the region from 20E,14S to 21E,15S.

If you wanted to extract such a lat/long window from a
projected file, you could use the gdalwarp utility to
extract and reproject the desired area.

eg.
gdalwarp -te 20 -15 21 -14 -t_srs WGS84 in.tif out.tif
