v10.0.0

What's new

• In this release, we got rid of sharp. Now "looks-same" package has no compiled dependencies, so there should be no errors trying to install looks-same version on old/new version of node.js.
• Increased performance when comparing images with lots of different pixels (up to 3x)
• Improved result difference images compression
• Reduced total "node_modules" size (41M -> 660K)

💣 Breaking changes

• formats, other than png, are not supported

out of bounds with createDiffImage: true

v8.2.2

🐛 Bug fixes

fix typings for looksSame with createDiffImage: true

v8.2.0

🚀 Improvements:

Add an ability to calculate image difference and image equality simultaneously

If you need both co compare images and create diff image, you can pass option createDiffImage: true,
it would work faster than two separate function calls:

const {
    equal,
    diffImage,
    differentPixels,
    totalPixels,
    diffBounds,
    diffClusters
} = await looksSame('image1.png', 'image2.png', {createDiffImage: true});

if (!equal) {
    await diffImage.save('diffImage.png');
}

v8.1.0

🚀 Improvements:

• looks-same now supports the following image formats: heic, heif, avif, jpeg, jpg, png, raw, tiff, tif, webp, gif, jp2, jpx, j2k, j2c

• If you want to build diff image as jpeg buffer, you can do:

  await looksSame.createDiff({
      reference: '/path/to/reference/image.png',
      current: '/path/to/current/image.png',
      extension: 'jpeg',
  });

v8.0.0

💣 Breaking changes

• drop support of node versions less than 12
• drop old node-style callback interface support

How it used before:

looksSame('image1.png', 'image2.png', function(error, {equal}) {
    // ...
});

How it use now:

const {equal} = await looksSame('image1.png', 'image2.png');

v4.0.0

• Update nodejs to 6 version
• Add ability to make ignore antialiasing less strict
