CurveClosed

CurveClosed

is an option for JoinedCurve that specifies whether individual curve components should be closed curves.

Details

  • The setting JoinedCurve[{component1,component2,…},CurveClosed->{close1,close2,…}] specifies whether individual component curves should be closed.
  • JoinedCurve[{component1,…},CurveClosed->close] indicates the whether all component curves should be closed.

Examples

open all close all

Basic Examples  (1)

Curve with a single open Bézier curve segment:

Wolfram Language code: Graphics[JoinedCurve[BezierCurve[{{-1, 0}, {-1, 2}, {1, 2}, {1, 0}}]]]

Curve with a single closed Bézier curve segment:

Wolfram Language code: Graphics[JoinedCurve[BezierCurve[{{-1, 0}, {-1, 2}, {1, 2}, {1, 0}}], CurveClosed -> True]]

Scope  (1)

Specify whether each component is closed individually:

Wolfram Language code: Graphics[JoinedCurve[{{Line[{{-2, 0}, {-2, 2}, {0, 4}, {2, 2}, {2, 0}}]}, {BSplineCurve[{{-1, 1}, {-1, 2}, {0, 3}, {1, 2}, {1, 1}}]}}, CurveClosed -> {True, False}]]
Wolfram Language code: Graphics[JoinedCurve[{{Line[{{-2, 0}, {-2, 2}, {0, 4}, {2, 2}, {2, 0}}]}, {BSplineCurve[{{-1, 1}, {-1, 2}, {0, 3}, {1, 2}, {1, 1}}]}}, CurveClosed -> {False, True}]]

Properties & Relations  (1)

Components of filled curves are always closed:

Wolfram Language code: Graphics[{EdgeForm[Blue], Pink, FilledCurve[{{Line[{{-2, 0}, {-2, 2}, {0, 4}, {2, 2}, {2, 0}}]}, {BSplineCurve[{{-1, 1}, {-1, 2}, {0, 3}, {1, 2}, {1, 1}}]}}]}]
