The wscn:DocumentParametersType type contains all of the image acquisition settings the scan device uses when creating the scan documents in the current PostScan job.

wscn:Format: The image file format in which the scan document(s) to be created.

wscn:CompressionQualityFactor: An integer value used by lossy compression types to determine the amount of acceptable image loss.

wscn:ImagesToTransfer: The number of images the scan device is to scan for the current job.

wscn:InputSource: The physical source of the original media to be scanned into a scan document(s).

wscn:FilmScanMode: The exposure type of the film to be scanned. This element is valid only if the wscn:InputSource element is set to a value of Film.

wscn:ContentType: The main characteristics of the original document.

wscn:InputSize: Describes the scannable media size and how to detect it.

wscn:Exposure: Describes whether the scan device automatically employs image processing techniques to reduce the background of the document to a white image or adjust the image processing by the values supplied.

Wscn:Scaling: The scaling factors for both the slow and fast scan directions of the scanned image.

Wscn:Rotation: The amount to rotate each image of a scanned document.

Wscn:MediaSides: The parameters that are unique to each physical side of the media to be scanned. Many duplex-capable scanners allow setting different scan regions, color processing, and resolutions for each physical side of the media to be scanned.
