Circle - Documentation

Usage (signatures)

board.create('circle', [center, radius]);

Parameters

Name	Type	Description
`center`	PointLike
`radius`	NumberLike	The absolute value of this number is taken as radius

Example

// Create a circle providing two points
var p1 = board.create('point', [2.0, 2.0]),
    c1 = board.create('circle', [p1, 3]);

// Create another circle using the above circle
var c2 = board.create('circle', [function() { return [p1.X(), p1.Y() + 1];}, function() { return c1.Radius(); }]);

board.create('circle', [center, point]);

Parameters

Name	Type	Description
`center`	PointLike
`point`	PointLike	Point on circle, defining the radius

Example

// Create a circle providing two points
var p1 = board.create('point', [2.0, 2.0]),
    p2 = board.create('point', [2.0, 0.0]),
    c1 = board.create('circle', [p1, p2]);

board.create('circle', [center, line]);

Parameters

Name	Type	Description
`center`	PointLike
`line`	Line	Line, the distance of its start and end point of the determines the radius

Example

// Create a line providing two points
var p1 = board.create('point', [2.0, 2.0]),
    p2 = board.create('point', [2.0, 0.0]),
    l1 = board.create('line', [p1, p2]);

// Create another circle using the above circle
var p3 = board.create('point', [3.0, 2.0]),
    c = board.create('circle', [p3, l1]);

board.create('circle', [center, circle]);

Parameters

Name	Type	Description
`center`	PointLike
`circle`	Circle	The circle radius is copied from the radius of that circle

Example

// Create a circle providing two points
var p1 = board.create('point', [2.0, 2.0]),
    p2 = board.create('point', [2.0, 0.0]),
    c1 = board.create('circle', [p1, p2]);

// Create another circle using the above circle
var p3 = board.create('point', [3.0, 2.0]),
    c2 = board.create('circle', [p3, c1]);

board.create('circle', [circle, t]);

Parameters

Name	Type	Description
`circle`	Circle
`t`	Transfomation

Examples

var t = board.create('transform', [2, 1.5], {type: 'scale'});
var c1 = board.create('circle', [[1.3, 1.3], [0, 1.3]], {strokeColor: 'black', center: {visible:true}});
var c2 = board.create('circle', [c1, t], {strokeColor: 'black'});

var li = board.create('line', [1,1,1], {strokeColor: '#aaaaaa'});
var reflect = board.create('transform', [li], {type: 'reflect'});

var c1 = board.create('circle', [[-2,-2], [-2, -1]], {center: {visible:true}});
var c2 = board.create('circle', [c1, reflect]);
