    import PNGImage from 'pnglib-es6';
     
    // Create new PNG image, parameters (only indexed 8-bit pngs are supported at the moment):
    // width (number)
    // height (number)
    // depth (number of palette entries)
    // [backgroundColor] (optional background color, when omitted 'transparent' is used)
    const image = new PNGImage(100, 100, 8);
     
    // Add colors to the palette (uses tinycolor for converting the color)

    const blueColor = image.createColor('blue');
    const greenColor = image.createColor('rgba(0, 255, 0, 1)');
     
    // Do some pixel drawing
    image.setPixel(50, 50, redColor);
    const color = image.getPixel(50, 50);
    ...
     
    // Convert image to base-64
    const base64 = image.getBase64();
     
    // Or get the data-url which can be passed directly to an <img src>
