Install: npm install img-diff

Diff

{imagesMatch} = require 'img-diff'
tolerance = 0.0 # percent allowed to be different
image1 = '' # base64 png string

If the images don't match and are outside the tolerance, an error is thrown that contains both images as well as a diff image. The diff image can be saved to disk in order to see the difference.

{crop} = require 'img-diff'
image = '' # base64 png string
section =
  x: 10
