This is example.

import React from 'react'
import { useSvgDrawing } from '@svg-drawing/react'

const Drawing = () => {
  const [renderRef, draw] = useSvgDrawing()
  // Drawing area will be resized to fit the rendering area
  return <div style={{ width: 500, height: 500 }} ref={renderRef} />
}

useSvgDrawing options.

const [renderRef, draw] = useSvgDrawing({
  penWidth: 10, // pen width
  penColor: '#e00', // pen color
  close: true, // Use close command for path. Default is false.
  curve: false, // Use curve command for path. Default is true.
  delay: 60, // Set how many ms to draw points every.
  fill: '', // Set fill attribute for path. default is `none`
})

Drawing methods.

// svg-drawing hooks
const [renderRef, draw] = useSvgDrawing()

// Call the SvgDrawing. Access the current settings of penWidth, penColor etc
// Details are https://github.com/kmkzt/svg-drawing/tree/master/packages/core.
const logger = useCallback(() => {
  if (!draw.ref.current) return
  console.log(draw.ref.current.penColor) // #333
  console.log(draw.ref.current.penWidth) // 1
}, [])

// Erase all drawing.
return <button onClick={draw.clear}>clear</button>
// Undo drawing.
return <button onClick={draw.undo}>undo</button>

// Download image.
const handleDownload = useCallback(() => {
  draw.download() // default svg download
  draw.download({ extension: 'svg', filename: 'a.svg'})
  draw.download({ extension: 'png', filename: 'b.png'})
  draw.download({ extension: 'jpg', filename: 'c.jpg'})
}, [draw.download])

// Chage parameter
const handleChangeParameter = useCallback(() => {
  // Change pen config
  draw.changePenColor('#00b')
  // Change pen width
  draw.changePenWidth(10)
  // Change fill attribure of svg path element.
  draw.changFill('#00b')
  // Change throttle delay of  drawing
  draw.changeDelay(10)
  // Set whether to use curved comma for svg path element.
  draw.changCurve(false)
  // Set whether to use curved comma for svg path element.
  draw.changeClose(true)
}, [draw])

// get svgXML
// return SVGElement
const loggerXML = useCallback(() => {
  console.log(draw.getSvgXML()) // <svg width="502" height="502"><path stroke-width="3" stroke="#000" fill="none" stroke-linejoin="round" stroke-linecap="round" d="M 156.671875 284.7265625 C 156.671875 286.1465625 156.671875 287.89984375 156.671875 291.83984375 ...
