The image contains black or grey filling regions which are added to the image after skew correction. Can this behavior be changed?
When deskewing the image, FineReader Engine determines the color of the filling areas automatically. Usually, it is the same as the background color of the image however you may want to choose the color on your own.
To do this change the IPrepareImageMode object passed to add-image methods:
BackgroundFillingColor = 16777215 ; white
