photo-to-scan

A simple JavaScript class which converts a document photo to a scan-like image.

Far from perfect. Made for demo purposes.

API

PhotoScan(imageSource[, options]) - constructor

• imageSource: string: Source of the photo
• options: { luminanceThreshold: number; grayscale: number; brightness: number } (optional): Set of options for tuning the output scan
  • Default options: luminanceThreshold: 200, grayscale: 1, brightness: 1.5

PhotoScan.getCanvas() - returns HTMLCanvasElement of the scan

How it works?

const scan = new PhotoToScan('./image.jpg');
const canvas = scan.getCanvas(); // Result canvas

// e.g. Append it as a child
element.appendChild(canvas);
