Add a 'Stamp' widget.
Place one or multiple stamps on scanned pages in defined locations. A stamp is understood here as - a transparent text in a transparent frame with no borders - an opaque text on an opaque background with no borders. Stamp parameters: - text - font - foreground colour - background colour - angle of rotation - transparency. Locations: - centre - cardinal directions - inter-cardinal directions.
