Function distanceFromHash

plugins/plugin-hash/src/index.ts:80–85

* Calculates the hamming distance of the current image and a hash based on their perceptual hash * @param compareHash hash to compare to * @returns a number ranging from 0 to 1, 0 means they are believed to be identical * @example * ```ts * import { Jimp } from "jimp"; * * cons

(image: I, compareHash: string)

   * ```
