Attributes

In addition to the universal attributes, the following attributes are supported.

Name	Type	Default Value	Description
radiusWidth	string \| number	0	Width of the rounded corner. The width and height are the same when only the width is set.
radiusHeight	string \| number	0	Height of the rounded corner. The width and height are the same only when the height is set.
radius	string \| number \| Array<string \| number>	0	Radius of the rounded corner. You can set separate radiuses for four rounded corners.
fill	ResourceColor	Color.Black	Color of the fill area.

strokeLineCap	LineCapStyle	LineCapStyle.Butt	Cap style of the stroke.
strokeLineJoin	LineJoinStyle	LineJoinStyle.Miter	Join style of the stroke.
strokeMiterLimit	number \| string	4	Limit on the ratio of the miter length to the value of strokeWidth used to draw a miter join. The miter length indicates the distance from the outer tip to the inner corner of the miter. NOTE This attribute must be set to a value greater than or equal to 1 and takes effect when strokeLineJoin is set to LineJoinStyle.Miter.
strokeOpacity	number \| string \| Resource	1	Stroke opacity. 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.
