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 use this, add the following flags to Flags property (DeskewCommandFlags.UseCheckDeskew | DeskewCommandFlags.UseLineDetectionCheckDeskew)
For more information, refer to Introduction to Image Processing With LEADTOOLS and Deskewing.
Runs the DeskewCommand on an image and straightens it.
