# Circle The **\** component is used to draw a circle. > **NOTE** > > This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version. ## Child Components Not supported ## APIs Circle(options?: {width?: string | number, height?: string | number}) **Parameters** | Name| Type| Mandatory| Description| | -------- | -------- | -------- | -------- | | width | string \| number | No| Width of the circle.
Default value: **0**| | height | string \| number | No| Height of the circle.
Default value: **0**| ## Attributes In addition to the [universal attributes](ts-universal-attributes-size.md), the following attributes are supported. | Name| Type| Description| | -------- | -------- | -------- | | fill | [ResourceColor](ts-types.md) | Color of the fill area.
Default value: **Color.Black**| | fillOpacity | number \| string \| [Resource](ts-types.md#resource)| Opacity of the fill area.
Default value: **1**| | stroke | [ResourceColor](ts-types.md) | Stroke color. If this attribute is not set, the component does not have any stroke.| | strokeDashArray | Array<Length> | Stroke dashes.
Default value: **[]** | | strokeDashOffset | number \| string | Offset of the start point for drawing the stroke.
Default value: **0**| | strokeLineCap | [LineCapStyle](ts-appendix-enums.md#linecapstyle) | Cap style of the stroke.
Default value: **LineCapStyle.Butt**| | strokeLineJoin | [LineJoinStyle](ts-appendix-enums.md#linejoinstyle) | Join style of the stroke.
Default value: **LineJoinStyle.Miter**
**NOTE**
This attribute does not work for the **\** component, which does not have corners. | | strokeMiterLimit | number \| string | Limit on the ratio of the miter length to the value of **strokeWidth** used to draw a miter join.
Default value: **4**
**NOTE**
This attribute does not take effect for the **\** component, because it does not have a miter join.| | strokeOpacity | number \| string \| [Resource](ts-types.md#resource)| Stroke opacity.
Default value: **1**
**NOTE**
The value range is [0.0, 1.0]. If the set value is less than 0.0, **0.0** will be used. If the set value is greater than 1.0, **1.0** will be used.| | strokeWidth | Length | Stroke width.
Default value: **1**| | antiAlias | boolean | Whether anti-aliasing is enabled.
Default value: **true**| ## Example ```ts // xxx.ets @Entry @Component struct CircleExample { build() { Column({ space: 10 }) { // Draw a circle whose diameter is 150. Circle({ width: 150, height: 150 }) // Draw a circle whose diameter is 150 and stroke color is red. (If the width and height values are different, the smaller value will be used as the diameter.) Circle() .width(150) .height(200) .fillOpacity(0) .strokeWidth(3) .stroke(Color.Red) .strokeDashArray([1, 2]) }.width('100%') } } ``` ![en-us_image_0000001219744191](figures/en-us_image_0000001219744191.png)
