jsxgraph - 多角形、円などのjsxgraph反射

Question

ポイントの反射のオプションがあります (リンク)。多角形、円、線、角度などの他の形状の反射のオプションはありますか。これを試しましたが、円では機能しませんが、点ではうまく機能します。

        var board = JXG.JSXGraph.initBoard('jxgbox', { boundingbox: [-5, 5, 5, -5], axis: true });
    linePt1 = board.create('point',[0,0],{name:''});
    linePt2 = board.create('point',[2,2],{name:''});

    p1 = board.create('point',[1,3],{name:''});
    p2 = board.create('point',[1,2],{name:''});
    c1 = board.create('circle', [p1, p2]);

    theLine = board.create('line',[linePt1,linePt2],{dash:1});


    i1 = board.create('point',[3,3],{name:''});
    i2 = board.create('point',[3,2],{name:''});
    c2 = board.create('circle', [i1, i2]);

    initialPt = board.create('point',[3,1],{name:'initial pt'});
    transform = board.create('transform',[theLine],{type:'reflect'});
    board.create('point',[initialPt,transform],{name:'reflection'});

    transform1 = board.create('transform',[theLine],{type:'reflect'});
    board.create('circle',[c2,transform1],{name:'reflection1'});
    board.update();

ありがとう
