how to get canvas data as base64?

[jessicaanhdao]

So what I did was
have images : [] in state
then called a function that gets binary from canvas tag. If you check from Inspect, there are 4 canvases, one of them is our drawing, one is the white canvas, one is the brush and one is something else. The second canvas is where our drawing is.

let canvas = document.getElementsByTagName('canvas');
    let localImages = []
    for(let c of canvas) {
      localImages.push(c.toDataURL())
    }
    this.setState({
      images : localImages
    })

then in render()

<img src={this.state.images[1]}/>
