useSegment

Hook used to create segment of a circle.

Configuration

note

useSegment will draw a segment counter-clockwise, starting from the right centre position, as useArc.

If you wish to create a segment facing to other side, please use rotate.

(SegmentConfig | undefined) useSegment accepts following configurations:

Property	Type	Default	Description
radius	number	100	Radius of outer arc of the segment.
angle	number	60	Angle of the segment, in degrees.

extends Primitive Configuration

(PrimitiveConfig) Base configurations for all primitives.

Property	Type	Default	Description
scale	number | Vertex	1	Scaling factor of the primitive. If Vertex is provided, it will scale x and y dimension accordingly (optional).
rotate	number	0	Rotation of the primitive, in degrees, in clockwise manner (optional).
position	Vertex	{ x: 0, y: 0 }	Moving distance away from the primitive drawing centre. By default, primitive will start drawing in origin (0, 0) (optional).

info

scale, rotate and position can be considered as transformation of polygon after drawn, where position can be considered as transform: translate of css to the primitive.

The polygon will first be scaled, then rotated and lastly, translated.

Returns

(Primitive) All primitive return the following properties:

Property	Type	Description
vertices	Vertex[]	Vertices of the primitive.
edges	Edge[]	Edges of the primitive.
faces	Face[]	Faces of the primitive.
centroid	Vertex	Centroid (geometric centre) of primitive.
boundingBox	BoundingBox	Space constraint of the primitive, with properties x, y, width and height.
svgPath	string	SVG path representing the shape of the primitive.
drawToCanvas	(ctx: CanvasRenderingContext2D) => void	Callback that draws the primitive to a canvas context.
modifyConfig	(newConfig: Partial<SegmentConfig>) => void	Callback to update the configuration of the primitive.

Example

import { useSegment } from "react-use-polygon";

const segment = useSegment({ radius: 80, angle: 45, rotate: 30 });
