Class Detail
Mirrorelement(p1,p2)
A mirror element is determined by the reflection of a given point across another given point.
Parameters:
{JXG.Point|JXG.Line|JXG.Curve|JXG.Ppolygon_JXG.Point} p1,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 t = board.create('transform', [Math.PI, mirr], {type: 'rotate'});

        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', [[-1, -1, -0.5, -1, -1, -0.5], [-3, -2, -2, -2, -2.5, -2.5]]);
        var cu2 = board.create('mirrorelement', [cu1, mirr], {strokeColor: 'red'});

        var pol1 = board.create('polygon', [[-3,-2], [-1,-4], [-2,-0.5]]);
        var pol2 = board.create('mirrorelement', [pol1, mirr]);
