Some scanners have the ability to detect the orientation of a page in the feeder, and can pass this information along in IG_ISIS_TAG_SCANORIENTATION. Your application can use this information to, for example, scan only 8.5 inches of a landscape letter-sized page rather than scanning 17 inches and then cropping the data.
