Why not just use Leptonica to threshold your image *before* you pass
the PIX to api.SetImage()? You can do something simple:

"Unofficial Leptonica v1.68 Documentation" website
(http://tpgit.github.com/UnOfficialLeptDocs/index.html). See that page
for its list of improvement over the Official Leptonica website.

You can see the actual problem by looking at
http://tpgit.github.com/Leptonica/tiffio_8c_source.html#l00274, where

not 2 as this image contains.
