# Map Icon
<flow-map-icon>
The Map Icon component registers an icon to use on a map.
Map icons are used to render point data on symbol
-type map layers. SVG and PNG icons are supported.
To maximize image quality on high-resolution ('retina') displays, icon images should be provided at twice the final display size. For example, for a target size of 20x20px, the icon image should be 40x40px and pixel-density
should be set to 2 (the default value).
When used as a child element of a Map component, the icon is registered for use on that map only and the icon's name
attribute must be unique for that map. When used outside of a Map component, the icon is registered globally for use on all maps and its name
attribute must be globally unique.
