go_bezier_spline_destroy ()

void
go_bezier_spline_destroy (GOBezierSpline *sp);

Destroys the given structures after cleaning all allocated fields.

go_bezier_spline_init ()

GOBezierSpline *
go_bezier_spline_init (double const *x,
                       double const *y,
                       int n,
                       gboolean closed);

x and y values must be valid and finite. The returned structure contains the x and y coordinates of all control points, including the incoming data. the n and closed fields are just copies of the corresponding arguments.

go_bezier_spline_to_cairo ()

void
go_bezier_spline_to_cairo (GOBezierSpline *sp,
                           cairo_t *cr,
                           gboolean horiz_flip);

Renders the spline in \a cr

go_bezier_spline_to_path ()

GOPath *
go_bezier_spline_to_path (GOBezierSpline *sp);

Builds a GOPath using the control points evaluated in go_bezier_spline_init.

GOBezierSpline

typedef struct {
	double *x, *y;
	int n;
	gboolean closed;
} GOBezierSpline;
