Element Detail
Mirrorelement
A mirror element is determined by the reflection of a given point across another given point.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "mirrorelement".

Possible parent array combinations are:
{JXG.Point|JXG.Line|JXG.Curve|JXG.Ppolygon} p1
{JXG.Point} p2

The constructed element is the mirror image of p2 across p1.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
        // point of reflection
        var mirr = board.create('point', [-1,-1], {color: '#aaaaaa'});

        var p1 = board.create('point', [-3,-1], {name: "A"});
        var q1 = board.create('mirrorelement', [p1, mirr], {name: "A'"});

        var l1 = board.create('line', [1, -5, 1]);
        var l2 = board.create('mirrorelement', [l1, mirr]);

        var cu1 = board.create('curve', [[-3, -3, -2.5, -3, -3, -2.5], [-3, -2, -2, -2, -2.5, -2.5]], {strokeWidth:3});
        var cu2 = board.create('mirrorelement', [cu1, mirr], {strokeColor: 'red', strokeWidth:3});

        var pol1 = board.create('polygon', [[-6,-2], [-4,-4], [-5,-0.5]]);
        var pol2 = board.create('mirrorelement', [pol1, mirr]);

        var c1 = board.create('circle', [[-6,-6], [-6, -5]]);
        var c2 = board.create('mirrorelement', [c1, mirr]);

        var a1 = board.create('arc', [[1, 1], [0, 1], [1, 0]], {strokeColor: 'red'});
        var a2 = board.create('mirrorelement', [a1, mirr], {strokeColor: 'red'});

        var s1 = board.create('sector', [[-3.5,-3], [-3.5, -2], [-3.5,-4]], {
                          anglepoint: {visible:true}, center: {visible: true}, radiuspoint: {visible: true},
                          fillColor: 'yellow', strokeColor: 'black'});
        var s2 = board.create('mirrorelement', [s1, mirr], {fillColor: 'yellow', strokeColor: 'black', fillOpacity: 0.5});

        var an1 = board.create('angle', [[-4,3.9], [-3, 4], [-3, 3]]);
        var an2 = board.create('mirrorelement', [an1, mirr]);
