Практическое руководство. Скругление углов объекта RectangleGeometry
Для скругления углов RectangleGeometry, задайте его RadiusX и RadiusY свойства в значение больше нуля. Чем больше значения, тем больше радиус скругления углов прямоугольника.
Пример
В следующем примере показано несколько RectangleGeometry объектов с разными RadiusX и RadiusY параметры. RectangleGeometry Объекты отображаются с помощью Path элементов.
