Class Detail
Reflection(p,l)
A reflected point is given by a point and a line. It is determined by the reflection of the given point
against the given line.
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]);
- Parameters:
- {JXG.Point_JXG.Line} p,l
- The reflection point is the reflection of p against l.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
