Class Detail
Tapemeasure(start,end,)
- Parameters:
- {Array_Array} start,end,
- The two arrays give the initial position where the tape measure is drawn on the board.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
// Create atape measure var p1 = board.create('point', [0,0]); var p2 = board.create('point', [1,1]); var p3 = board.create('point', [3,1]); var tape = board.create('tapemeasure', [[1, 2], [4, 2]], {name:'dist'});
