Element Detail
mirrorelement
A mirror element is determined by the reflection of a given point, line, circle, curve, polygon 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]);

Attribute Detail
{Point} center
Attributes of circle center, i.e. the center of the circle, if a circle is the mirror element and the transformation type is 'Euclidean'
Defined in: options.js.

{Point} point
Attributes of mirror point, i.e. the point along which the element is mirrored.
Defined in: options.js.

{String} type
Type of transformation. Possible values are 'Euclidean', 'projective'. If the value is 'Euclidean', the mirror element of a circle is again a circle, otherwise it is a conic section.
Defined in: options.js.

Default Value:
  'Euclidean'
