Element Detail
Reflection
A reflected element (point, line or curve) is given by a given object of the same type and a line of reflection. It is determined by the reflection of the given element across the given line.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "reflection".

Possible parent array combinations are:
{JXG.Point|JXG.Line|JXG.Curve|JXG.Polygon} p
{JXG.Line} l

The reflection element is the reflection of p across the line l.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
var p1 = board.create('point', [0.0, 4.0]);
var p2 = board.create('point', [6.0, 1.0]);
var l1 = board.create('line', [p1, p2]);
var p3 = board.create('point', [3.0, 3.0]);

var rp1 = board.create('reflection', [p3, l1]);

				
				
        // Reflection of more elements
        // reflection line
        var li = board.create('line', [1,1,1], {strokeColor: '#aaaaaa'});

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

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

        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('reflection', [cu1, li], {strokeColor: 'red', strokeWidth:3});

        var pol1 = board.create('polygon', [[-6,-3], [-4,-5], [-5,-1.5]]);
        var pol2 = board.create('reflection', [pol1, li]);

        var c1 = board.create('circle', [[-2,-2], [-2, -1]]);
        var c2 = board.create('reflection', [c1, li]);

        var a1 = board.create('arc', [[1, 1], [0, 1], [1, 0]], {strokeColor: 'red'});
        var a2 = board.create('reflection', [a1, li], {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('reflection', [s1, li], {fillColor: 'yellow', strokeColor: 'black', fillOpacity: 0.5});

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