Magnifier widget

Magnifier is a widget that allows displaying images in 100% scaled size in a separate dedicated layer. In Magento it is used by the gallery widget for zooming the product images on product pages. It must be enabled in your local theme view.xml configuration file.

The Magnifier widget source is located in lib/web/magnifier/magnify.js.
