javascript - Changing Clickable Area of an Image without Resizing Image -


i working on php/javascript project action occurs when image clicked. image small, expand clickable area further around image without enlarging image itself. possible? below general idea of structure of i'm working on. 

<g id="pictures">  <image id="marker_image" cx="145" cy="460" r="1" preserveaspectratio="none"  x="136" y="451" width="18" height="18"   xmlns:xlink="http://www.w3.org/1999/xlink"   xlink:href="//link.thislink.com/image_assets/markers/pool.png"   style="opacity: 1" fill="#000000" fill-opacity="1" stroke="#000000"   stroke-opacity="1" stroke-width="2" stroke-linecap="round" stroke-  linejoin="round"></image> </g>

i'm new working svgs, i've read, think can use <g> add padding?

wrap image in div, make div big want using padding, , bind action on div instead of img
