Depending on what you mean, Leptonica has the ability to dewarp text page images [1] (although it currently doesn't seem to work very well with pages that only have short lines). See dewarptest.c [2] for an example. It can also do Projective transforms [3] via pixDeskewLocal() [4]. See baselinetest.c [5] for an example.
