Try this: in father component, add a ref

<ReactPaint {...props} ref="paint" />

presume the father component have a button to saveImage:

<button onClick={this.saveImage}>Upload</button>

and the handler function

saveImage(){
    const dataUrl = this.refs.paint.canvas.toDataURL('image/png') // or .toBlob(callback)
    // then post the dataUrl
}
