I sent to ocrsdk a pdf file which contains 4 pages with correctOrientation "true" parameter (I always do so). All pages was as A4 Portrait orientation. After recognition i received a pdf where pages 1-2-4 was as A4 Portrait, but page "3" as A4 Landscape. I think it is a bug in your page orientation algorithm. Please can I submit you original pdf file for bug correction?
PS: why I can`t attach a pdf to my question?
