Remarks
The Contrast element indicates the relative amount to enhance or reduce the contrast of the scanned document. A value of 0 indicates that the WSD Scan Service should make no adjustments to the scanned contrast.
All WSD Scan Services must support all values between, and including, -1000 to 1000. The services must internally map these values to the actual Contrast values that the scan device supports.
The WSD Scan Service can specify the optional Override and UsedDefault attributes only when the Contrast element is contained within a DocumentFinalParameters hierarchy. For more information about Override and UsedDefault and their usage, see DocumentFinalParameters.
