NAME¶
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
SYNOPSIS¶
#include <Unidraw/Graphic/splines.h>
DESCRIPTION¶
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.
OPENBSPLINE PROTECTED OPERATIONS¶
- OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- OpenBSpline's constructor is protected to prevent instantiation of the
abstract base class. The parameters are passed directly to the Vertices
constructor.
OPENBSPLINE SUBCLASS PUBLIC OPERATIONS¶
- S_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- F_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- SF_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- SFH_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- Constructors for the various predefined Rect subclasses.
CLOSEDBSPLINE PROTECTED OPERATIONS¶
- ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- ClosedBSpline's constructor is protected to prevent instantiation of the
abstract base class. The parameters are passed directly to the Vertices
constructor.
CLOSEDBSPLINE SUBCLASS PUBLIC OPERATIONS¶
- S_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- F_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
- SF_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* =
nil)
- SFH_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* =
nil)
- Constructors for the various predefined Rect subclasses.
