Readiris can detect the page orientation automatically and rotate the image when needed.
An example: you’re scanning a document where most pages have the portrait orientation but some are landscape because they contain large tables.
This option determines whether pages which were scanned at a 90°, 180° or 270° angle will be rotated left, right or turned upside down automatically before the page analysis and recognition begin.
Tip: select the proper document language before you scan (or load) the document!
Tip: detecting the page orientation takes a few seconds. Leave this option disabled when you are sure no image rotation is required.
Tip: the page deskewing (if enabled) takes place before the detection of the page orientation.
Tip: hold your cursor over a page’s thumbnail in the page toolbar and a tooltip will tell you if the page was rotated automatically.
