CurveClosed

CurveClosed

是 JoinedCurve 的一个选项，指定单个曲线分量是否是闭合的曲线.

更多信息

  • 设置 JoinedCurve[{component1,component2,…},CurveClosed->{close1,close2,…}] 指定单个分量曲线是否应该是闭合的.
  • JoinedCurve[{component1,…},CurveClosed->close] 表示所有分量曲线是否都应该是闭合的.

范例

打开所有单元 关闭所有单元

基本范例  (1)

具有单个开放式 Bézier 曲线段的曲线：

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

具有单个闭合式 Bézier 曲线段的曲线：

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

范围  (1)

分别指定每个分量是否是闭合的：

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}]]

属性和关系  (1)

填充曲线的分量总是闭合的：

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}}]}}]}]
