WordPress Geo Mashup Mapstraction Custom Markers

/ Published in: JavaScript

Some common custom javascript for customizing geo mashup map markers for any map provider. The marker images used are 24 x 24 pixels, anchored at the bottom center, with no shadow. You'd put images in `wp_content/plugins/geo-mashup-custom/images` to use your own images with this snippet. The example images are the old small markers and are still in the distributed plugin, you can use them by replacing `custom_url_path` with just `url_path`.

(function() {
	
	GeoMashup.addAction( 'colorIcon', function( properties, icon, color_name ) {
		// For single category icons use the Geo Mashup color icon names, 
		// but the 24x24 ones in the custom image directory
		icon.image = properties.custom_url_path + '/images/mm_20_' + color_name + '.png';
		icon.iconShadow = '';
		icon.iconSize = [ 24, 24 ];
		icon.iconAnchor = [ 12, 24 ];
		icon.iconInfoWindowAnchor = [ 12, 1 ];
	} );

GeoMashup.addAction( 'objectIcon', function( properties, obj ) {

if ( obj.terms.category.length == 0 ) {

	    glow_options.iconAnchor = [ 11, 27 ];
	} );
