<readonly> area :number

The area of this Circle.

Source - geom/Circle.js, line 387

bottom :number

The sum of the y and radius properties. Changing the bottom property of a Circle object has no effect on the x and y properties, but does change the diameter. Gets or sets the bottom of the circle.

Source - geom/Circle.js, line 360

diameter :number

The largest distance between any two points on the circle. The same as the radius * 2. Gets or sets the diameter of the circle.

Source - geom/Circle.js, line 233

empty :boolean

Determines whether or not this Circle object is empty. Will return a value of true if the Circle objects diameter is less than or equal to 0; otherwise false. If set to true it will reset all of the Circle objects properties to 0. A Circle object is empty if its diameter is less than or equal to 0. Gets or sets the empty state of the circle.

Source - geom/Circle.js, line 410

left

The x coordinate of the leftmost point of the circle. Changing the left property of a Circle object has no effect on the x and y properties. However it does affect the diameter, whereas changing the x value does not affect the diameter property.

Source - geom/Circle.js, line 279

radius :number

The length of a line extending from the center of the circle to any point on the circle itself. The same as half the diameter. Gets or sets the radius of the circle.

Source - geom/Circle.js, line 256

right :number

The x coordinate of the rightmost point of the circle. Changing the right property of a Circle object has no effect on the x and y properties. However it does affect the diameter, whereas changing the x value does not affect the diameter property. Gets or sets the value of the rightmost point of the circle.

Source - geom/Circle.js, line 306

top :number

The sum of the y minus the radius property. Changing the top property of a Circle object has no effect on the x and y properties, but does change the diameter. Gets or sets the top of the circle.

Source - geom/Circle.js, line 333

<readonly> type :number

The const type of this object.

Source - geom/Circle.js, line 54

x :number

The x coordinate of the center of the circle.

Source - geom/Circle.js, line 26

y :number

The y coordinate of the center of the circle.
