Property Value
The value of this property depends on the UnitMode property setting. When the UnitMode property is vikScanInch, the unit of this property is inches.
Explanation
The RectLeft property sets the left position of the area on the image to bescanned. This property value is enabled when the UiMode property is vikScanNONUI and the PaperSize property is 0. (If the PaperSize property is set to a value other than 0, the scan device will scan the area specifed by that size.)
After the scan has completed, the exact dimensions (in the units specified in the UnitMode property) of the actual area scanned are reset into the value of the RectBottom, RectLeft, RectRight, and RectTop properties. (These dimensions may be slightly different than the value set by the user prior to the scan). If you wish to use the default values of the scan device, set the RectLeft, RectTop, RectRight, and RectBottom properties to 0.
Note: The RectBottom, RectLeft, RectRight, and RectTop properties are disabled when using a digital camera.
