        <var name="magnifier">

            <var name="fullscreenzoom">20</var>  <!-- Zoom for fullscreen (integer)-->

            <var name="top"></var> <!-- Top position of magnifier -->

            <var name="left"></var> <!-- Left position of magnifier -->

            <var name="width">400</var> <!-- Width of magnifier block -->

            <var name="height">400</var> <!-- Height of magnifier block -->

            <var name="eventType">hover</var> <!-- Action that atcivates zoom (hover/click) -->

            <var name="enabled">true</var> <!-- Turn on/off magnifier (true/false) -->

            <var name="mode">outside</var> <!-- Zoom type (outside/inside) -->

        </var>

Its not working .

        </var>

  </view>

Try this,

To create and theme and override a view.xml

app/design/frontend/{Vendor}/{theme-name}/registration.php

<?php                

MagentoFrameworkComponentComponentRegistrar::register(

MagentoFrameworkComponentComponentRegistrar::THEME,

'frontend/{Vendor}/{theme-name}',

__DIR__);

then create theme.xml

app/design/frontend/{Vendor}/{theme-name}/theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">

<title>Theme Title</title>

<parent>Magento/blank</parent></theme>

Check whether the theme is installed by the following query via mysql

select * from theme;

then add

app/design/frontend/{Vendor}/{theme-name}/etc/view.xml

and add composer.json in

app/design/frontend/{vendor}/{theme-name}/composer.json

then add the below code in it

{

"name": "{vendor}/{theme-name}",

"description": "N/A",

"require": {

    "php": "~5.5.0|~5.6.0|~7.0.0",

    "magento/theme-frontend-blank": "100.0.*",

    "magento/framework": "100.0.*"

},

"type": "magento2-theme",

"version": "100.0.1",

"license": [

    "OSL-3.0",

    "AFL-3.0"

],

"autoload": {

    "files": [

        "registration.php"

    ]

}}

You must configure your theme to see the changes on frontend.

To configure new theme for your store, just follow the below steps :

Go to-> content-> configuration-> select your store-> then change the new theme by clicking drop down and save configuration.

NOTE : After creating theme setup:upgrade and once after configured theme cache:flush.

Hope this helps :)

according documentation custom theme files must be under following path:

/app/design/frontend/<Vendor>/<Theme>

So your view.xml should be there:

/app/design/frontend/<Vendor>/<Theme>/etc
