This is the interface for implementing custom rendering using canvas.

const onFillContent = (ctx, layer) => {
  const img = document.createElement('img')
  img.src = imgSrc

  const { _pxBounds } = layer
  const minX = _pxBounds.min.x
  const minY = _pxBounds.min.y
  const maxX = _pxBounds.max.x
  const maxY = _pxBounds.max.y

  const width = maxX - minX
  const height = maxY - minY

  img.onload = () => {
    ctx.drawImage(img, minX, minY, width, height)
  }
}

For example.

import L from 'leaflet'
import '@silen/leaflet-canvas'

const renderGroup = new L.FeatureGroup()
map.addLayer(renderGroup)

const geoJson = L.geoJson(
  {
    type: 'FeatureCollection',
    features,
  },
  {
    onFillContent,
    onEachFeature: (feature, layer) => {
      renderGroup.addLayer(layer)
