Polygon

Usage (signatures)

board.create('polygon', [vertices]);

Parameters

Name	Type	Description
`vertices`	Array	The polygon's vertices. If the first and the last vertex don't match the first one will be added to the array by the creator. Here, two points match if they have the same `id` attribute.

Examples

var p1 = board.create('point', [0.0, 2.0]);
var p2 = board.create('point', [2.0, 1.0]);
var p3 = board.create('point', [4.0, 6.0]);
var p4 = board.create('point', [1.0, 4.0]);

var pol = board.create('polygon', [p1, p2, p3, p4]);

var p = [[0.0, 2.0], [2.0, 1.0], [4.0, 6.0], [1.0, 3.0]];

var pol = board.create('polygon', p, {hasInnerPoints: true});

var f1 = () => [0.0, 2.0],
      f2 = () => [2.0, 1.0],
      f3 = () => [4.0, 6.0],
      f4 = () => [1.0, 4.0],
      cc1 = board.create('polygon', [f1, f2, f3, f4]);
      board.update();

board.create('polygon', [pol, t]);

Additionally, a polygon can be created by providing a polygon and a transformation (or an array of transformations). The result is a polygon which is the transformation of the supplied polygon.

Parameters

Name	Type	Description
`pol`	Polygon
`t`	Transformation

Example

var t = board.create('transform', [2, 1.5], {type: 'scale'});
var a = board.create('point', [-3,-2], {name: 'a'});
var b = board.create('point', [-1,-4], {name: 'b'});
var c = board.create('point', [-2,-0.5], {name: 'c'});
var pol1 = board.create('polygon', [a,b,c], {vertices: {withLabel: false}});
var pol2 = board.create('polygon', [pol1, t], {vertices: {withLabel: true}});

highlightByStrokeWidth

Description

By default, the strokewidths of the borders of a polygon are not changed during highlighting (only strokeColor and strokeOpacity are changed to highlightStrokeColor, and highlightStrokeOpacity). However, strokewidth is changed to highlightStrokewidth if an individual border gets the focus.
