For the basic usage, all you need to do is create an instance of Brusher and provide an image

import Brusher from 'brusher';

const brusher = new Brusher({
  image: 'abstract.png'
});

brusher.init();

Available Options

Here is the list of options that you may use

const brusher = new Brusher({
  image: 'abstract.png', // Path of the image to be used as a brush
  keepCleared: true,        // Put the blur back after user has cleared it
  stroke: 80,            // Stroke size for the brush
  lineStyle: 'round',    // Brush style (round, square, butt)
  autoBlur: false,       // Brusher will use the provided image for the blurry background
  autoBlurValue: 15,     // Blur strength in pixels
});

brusher.init();

A note on blurry background: although brusher is capable of generating blurry background by itself. It is recommended that you blur the image yourself and apply it to the body for improved performance. Brusher relies on CSS blur if you don't provide the blurry image. And rendering performance for the pre-provided blurred image would be of-cource much less than that applied using CSS. Here is the sample CSS that you may use for the background

body {
  background-size: cover;
  background-position: 0 0;
  background-attachment: fixed;
  background-image: url(path/to/blurred/image.jpg);
}
