Put the default magnify preview over the top of the thumbnail in magento2. Some fixes were required to make this work with touch screens and the full screen view.

Installation

composer require thousandmonkeys/m2-overlaymagnify-module
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy

Usage

It should just work.

Note this overrides the following settings from view.xml:

<var name="magnifier">
	<var name="top">100</var> <!-- Top position of magnifier -->
	<var name="left">45</var> <!-- Left position of magnifier -->
	<var name="width">7700</var> <!-- Width of magnifier block -->
	<var name="height">7700</var> <!-- Height of magnifier block -->
</var>
