<plastic-map-marker-svg>

Custom SVG map marker icons for google-map

See the live demo site for samples and code.

What is it?

The elements in this package allow you to create a collection of SVG icons that can be used with google-map-marker, or with the Google Maps Javascript API, in the same way you would use iron-iconset-svg to create a collection of icons for iron-icon.

The marker icon sets you create can be used in two ways, depending on your need:

• Retrieve the icon in code and asssign it to properties as needed.
• Use plastic-map-marker-svg instead of google-map-marker

Versions

There is a version for Polymer 3.0 projects and a version for Polymer 2.x projects.

Install for Polymer 3.0

npm i --save plastic-map-marker-svg

Install for Polymer 2.0

bower install --save plastic-map-marker-svg#^0.0.3

Creating a Marker Icon Set

To create a marker icon set you create a custom element with plastic-map-marker-set and include your SVG icon designs in that element (just like iron-iconset-svg):

Polymer 3.0

// file: sample-markers.js
import 'plastic-map-marker-set/plastic-map-marker-set.js';
const $_documentContainer = document.createElement('template');
$_documentContainer.setAttribute('style', 'display: none;');
$_documentContainer.innerHTML = `<plastic-map-marker-set name="sample-markers">

Design Considerations

It is important that each definition have:

• an id which is unique, and that no other g elements have an id
• a viewBox attribute - it defines the basis of the points in the SVG markup and allows the browser to scale the image as requested.

Not Really Data Binding, but ...

While it's not actual data binding, marker definitions can have substitution points (see example markers above), marked with [[some.data.path]] that will be substituted in when you request the marker.

Using Your Icons

In Code

You can get a google.map.icon object for your marker icon by calling the static method getMarkerSetIcon of the PlasticMapMarkerSet which returns a Promise for a google.map.icon object:

<google-map id="gm" style="width:100%;height:100%;" latitude="37.779" longitude="-122.3892" min-zoom="9" max-zoom="11" language="en" api-key="[[apiKey]]" on-google-map-ready="mapReady">
    <template is="dom-repeat" items="[[points]]">
        <google-map-marker slot="markers" latitude="[[item.lat]]" longitude="[[item.lng]]" icon="[[icon]]">
            <p>Yo</p>
        </google-map-marker>
    </template>
</google-map>

PlasticMapMarkerSet.getMarkerSetIcon('sample-markers', 'tdpin', 64, 96, myDataObject)
    .then((icon) => {
        this.icon = icon;
        this.points = [{
            lat: 37.779,
            lng: -122.3892
        }];
    });

With plastic-map-marker-svg

plastic-map-marker-svg extends google-map-marker (i.e. class PlasticMapMarkerSvg extends customElements.get('google-map-marker')) adding just the icon functions.

This is particularly useful if you are assigning different icons to different markers.

You use it in place of google-map-marker:

<plastic-aspect-ratio style="width:100%;" aspect-width="4" aspect-height="3">
    <google-map id="gm" style="width:100%;height:100%;" latitude="37.779" longitude="-122.3892" min-zoom="9" max-zoom="11" language="en" api-key="[[apiKey]]">
        <template is="dom-repeat" items="[[points]]">
            <plastic-map-marker-svg slot="markers" latitude="[[item.lat]]" longitude="[[item.lng]]" icon-name="[[item.markerStyle.iconName]]"
            icon-height="[[item.markerStyle.height]]" icon-width="[[item.markerStyle.width]]" icon-data="[[item.markerStyle.iconData]]">
            <p>Yo! Some infowindow stuff!</p>
            </plastic-map-marker-svg>
        </template>
    </google-map>
</plastic-aspect-ratio>

Note that the `icon-name' property is in the form set:icon e.g. "sample-set:flag".
