export default MyEditor

Props

Accessing the resulting image

The resulting image will have the same resolution as the original image, for that you can use getImage, regardless of the editor's size. If you want the image sized in the dimensions of the canvas you can use getImageScaledToCanvas.

import React, { useRef } from 'react'
import AvatarEditor from 'react-avatar-editor'

const MyEditor = () => {
  const editor = useRef(null);

  render() {
    return (
      <div>
        <AvatarEditor
          ref={editor}
          image="http://example.com/initialimage.jpg"
          width={250}
          height={250}
          border={50}
          scale={1.2}
        />
        <button onClick={() => {
          if (this.editor) {
            // This returns a HTMLCanvasElement, it can be made into a data URL or a blob,
            // drawn on another canvas, or added to the DOM.
            const canvas = editor.current.getImage()

            // If you want the image resized to the canvas size (also a HTMLCanvasElement)
            const canvasScaled = editor.current.getImageScaledToCanvas()
          }
        }}>Save</button>
      </div>
    )
  }
}

export default MyEditor

Adding drag and drop

We recommend using react-dropzone. It allows you to add drag and drop support to anything really easy. Here is an example how to use it with react-avatar-editor:

import React, { useState } from 'react'
import AvatarEditor from 'react-avatar-editor'
import Dropzone from 'react-dropzone'

const MyEditor = () => {
  const [image, setImage] = useState('http://example.com/initialimage.jpg')

  return (
    <Dropzone
      onDrop={(dropped) => setImage(dropped[0])}
      noClick
      noKeyboard
      style={{ width: '250px', height: '250px' }}
    >
      {({ getRootProps, getInputProps }) => (
        <div {...getRootProps()}>
          <AvatarEditor width={250} height={250} image={image} />
          <input {...getInputProps()} />
        </div>
      )}
    </Dropzone>
  )
}

Accessing the cropping rectangle

Sometimes you will need to get the cropping rectangle (the coordinates of the area of the image to keep), for example in case you intend to perform the actual cropping server-side.

getCroppingRect() returns an object with four properties: x, y, width and height; all relative to the image size (that is, comprised between 0 and 1). It is a method of AvatarEditor elements, like getImage().

Note that: getImage() returns a canvas element and if you want to use it in src attribute of img, convert it into a blob url.

const getImageUrl = async () => {
  const dataUrl = editor.current.getImage().toDataURL()
  const res = await fetch(dataUrl)
  const blob = await res.blob()

  return window.URL.createObjectURL(blob)
}

// Usage
const imageURL = await getImageUrl()

<img src={imageURL} ... />
