This command is typically used to automatically straighten scanned images, including bank checks. This command is available in the Document\Medical Toolkits.
This command contains a special algorithm for detecting the skewed checks, To do this add the following flags to Flags property (DeskewCommandFlags.UseCheckDeskew | DeskewCommandFlags.UseLineDetectionCheckDeskew)
In Silverlight and Windows Phone versions of LEADTOOLS, this image processing command will fail if the image data for the RasterImage object is stored internally using a Silverlight WriteableBitmap object. For more information, refer to Image Processing Command Limitations in Silverlight.
