diffImage

import { diffImage } from 'diffine-react/image';

const result = diffImage(before, after, { align: 'shift' });

(before: DiffPixels, after: DiffPixels, options?: DiffImageOptions) => DiffImageResult

final DiffImageResult result = diffImage(

DiffImageResult diffImage(DiffPixels before, DiffPixels after, [DiffImageOptions? options])

Compares two pictures pixel by pixel. Neither side has to be the same size as the other: what only one of them covers comes back as added or removed rather than as an error.

DiffImageOptions is how the two are compared, and DiffImageResult is what comes back.
