OpenBSpline, S_OpenBSpline, F_OpenBSpline, SF_OpenBSpline, SFH_OpenBSpline, ClosedBSpline, S_ClosedBSpline, F_ClosedBSpline, SF_ClosedBSpline, SFH_ClosedBSpline - structured graphics classes for open and closed B-splines
#include <Unidraw/Graphic/splines.h>
OpenBSpline and ClosedBSpline are Vertices subclasses that serve as abstract base classes for open and closed B-spline structured graphics. Predefined subclasses include S_OpenBSpline, F_OpenBSpline, and SF_OpenBSpline, which draw stroked, filled, and stroked-filled open B-splines, respectively; and S_ClosedBSpline, F_ClosedBSpline, and SF_ClosedBSpline, which draw stroked, filled, and stroked-filled closed B-splines, respectively. The SFH_OpenBSpline and SFH_ClosedBSpline subclasses are identical to their SF_-prefixed counterparts, except they can detect hits on their control points in addition to detecting hits on their visible parts. The stroked subclasses store a PSBrush, the filled subclasses store a PSPattern, and the stroked-filled subclasses store one of each.
