Class Detail
Perpendicularpoint(p,l)
A perpendicular point is given by a point and a line. It is determined by projecting the given point orthogonal onto the given line. This used in GEONExTReader only. All other applications should use orthogonal projection.
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 pp1 = board.create('perpendicularpoint', [p3, l1]);

				
				
				
				
					
						
Parameters:
{JXG.Line_JXG.Point} p,l
The constructed point is the orthogonal projection of p onto l.
Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
