No, it isn't. Its a simpler program than the one from autopano.kolor.com.
It works only for flat, single row pano's without much rotation.

Hmm, strange. probably the PTStitcher should be disabled then.. How does the
mac version of Panotools work without PTStitcher?

Yes.

Hmm, it is used by default, if "high quality tiff" is selected.. Or
it can be selected manually, when using nona with TIFF output.

Well, its just a matter if the libtiff that was used for enblend supports
compressed tif's. Which it really should (maybe not LZW, but at least
Deflate and some others..). If not enblend should be linked against a
libtiff that supports compression.

How do you create the lzw tiffs? Nona doesn't create LZW tiffs, but uses
Deflate.
