Hi,

I use Fine Reader (v.9) to ocr some PDF (images) files of old books. The results are usually very very good. But sometimes, say in a 100 pages document, some pages are not vertical but slightly inclined on one side (some few degrees are enough). Yes, like the Pisa tower... Then the ocr result worsens noticeably.

Is it possible to modify some pages of a image PDF document to correct them and make them look vertical?

Which software (preferably free) may I use to do it?
