Explanation
The Sharpness property sets the level of sharpness. The default value is 0.
Sharpness is enabled for certain Canon DR, Epson, Panasonic, and PFU scan drivers. When using an Epson scanner, the datasource will be "Epson Scan" which will allow the above gradated settings. Note that some Epson scanners, depending on the version, allow for only "on / off" settings. In this case the ImageKit will accept values of 0 or nonzero.
For Canon scanners, "edge enhancement" is used. For Epson scanners, the "unsharp mask" is used. For Panasonic scanners, "image quality" is used. For PFU scanners, "outline enhancement" is used.
This property is enabled when the UiMode is 2(ikScanNONUI). The possible setting values supported by a scan device can be retrieved using the GetCapEnum or the GetCapEnumVariant method.
