title: Change marker size in Google maps V3
body: <p>I am using <a href="https://stackoverflow.com/questions/7095574/google-maps-api-3-custom-marker-color-for-default-dot-marker/7686977#7686977">this explanation</a> of how to color a google maps marker by setting the icon using a <a href="http://code.google.com/apis/maps/documentation/javascript/reference.html#MarkerImage" rel="noreferrer">MarkerImage</a>, and the coloring works well.  But I can't make the scaledSize argument change the size of the marker.</p>
  
  <pre><code>    var pinColor = 'FFFF00';
      var pinIcon = new google.maps.MarkerImage(
          "http://chart.apis.google.com/chart?chst=d_map_pin_letter&amp;chld=%E2%80%A2|" + pinColor,
          new google.maps.Size(21, 34),
          new google.maps.Point(0,0),
          new google.maps.Point(10, 34),
          new google.maps.Size(2, 4));
      marker.setIcon(pinIcon);
  </code></pre>
  
  <p>What is the correct use of the scaledSize argument to change the marker size?  For example, how can I double the marker size?</p>
