Examples
Αυτά τα παραδείγματα χρησιμοποιούν την κατηγορία GraphicsPath και Graphics για να δημιουργήσουν και να χειραγωγήσουν Σημάδια σε μια επιφάνεια εικόνας. Το παράδειγμα δημιουργεί μια νέα εικόνα (του τύπου Tiff), καθαρίζει την επιφάνεια και τραβάει τα μονοπάτια με τη βοήθεια της κατηγορίας GraphicsPath. Στο τέλος, η μέθοδος DrawPath που εκτίθεται από την κατηγορία Graphics καλείται να κάνει τα μονοπάτια στην επιφάνεια.
