Getting Started

Simply import the transform function from the Legofy module, and then invoke it by passing in your img element.

import {transform} from 'legofy';
 
// ...
 
const imgElement = document.querySelector('img');
transform(imgElement);

Options

Brick Size

You can adjust the size of the bricks by using the second argument of the transform function — by default the factor is 0.05.

// ...
 
// Make the bricks twice the size of the default.
transform(imgElement, { factor: 0.1 });
 
// ...Or make them twice as small!
transform(imgElement, { factor: 0.025 });

As the brick isn't currently SVG — see ticket — larger bricks will look blurry.

Blend Mode

You can also change the mix-blend-mode value using the second argument — the default is overlay however screen, darken, color-burn, hard-light, soft-light all look good as blend modes.

// ...
 
// Change bricks to a more pastel colour.
transform(imgElement, { blendMode: 'screen' });

Re-rendering

By default when the window is resized no re-rendering will occur — it's entirely up to the developer to invoke transform again – and thankfully the transform function is idempotent.

import {throttle} from 'lodash';
import {transform} from 'legofy';
 
// ...
 
const imgElement = document.querySelector('img');
transform(imgElement);
 
//  ...
addEventListener('resize', throttle(() => transform(imgElement), 250));
