I\'m trying to display some bus routes using Google Data Layer, and then add some custom icon markers. Works great in Chrome and Firefox, but in IE

OK! I done this in my web,I used it in my angularJS project, I share it use Jquery. I try two ways to create the custom google map marker, this run code use canvg.js is the best compatibility for browser.the Commented-Out Code is not support IE11 urrently("scaledSize" and "optimized: false" together seems did the tricky).

var marker;
var CustomShapeCoords = [16, 1.14, 21, 2.1, 25, 4.2, 28, 7.4, 30, 11.3, 30.6, 15.74, 25.85, 26.49, 21.02, 31.89, 15.92, 43.86, 10.92, 31.89, 5.9, 26.26, 1.4, 15.74, 2.1, 11.3, 4, 7.4, 7.1, 4.2, 11, 2.1, 16, 1.14];

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 13,
    center: {
      lat: 59.325,
      lng: 18.070
    }
  });
  var markerOption = {
    latitude: 59.327,
    longitude: 18.067,
    color: "#" + "000",
    text: "ha"
  };
  marker = createMarker(markerOption);
  marker.setMap(map);
  marker.addListener('click', changeColorAndText);
};

function changeColorAndText() {
  var iconTmpObj = createSvgIcon( "#c00", "ok" );
  marker.setOptions( {
                icon: iconTmpObj
            } );
};

function createMarker(options) {
  //IE MarkerShape has problem
  var markerObj = new google.maps.Marker({
    icon: createSvgIcon(options.color, options.text),
    position: {
      lat: parseFloat(options.latitude),
      lng: parseFloat(options.longitude)
    },
    draggable: false,
    visible: true,
    zIndex: 10,
    shape: {
      coords: CustomShapeCoords,
      type: 'poly'
    }
  });

  return markerObj;
};

function createSvgIcon(color, text) {
  var div = $("<div></div>");

  var svg = $(
    '<svg width="32px" height="43px"  viewBox="0 0 32 43" xmlns="http://www.w3.org/2000/svg">' +

  var svgHtml = div[0].innerHTML;

  canvg(dd[0], svgHtml);

  var imgSrc = dd[0].toDataURL("image/png");

  var iconObj = {

This reference in MDN (Mozilla Developer Network) states that "Internet Explorer 8 and above only supports data URIs for images in CSS, , and ". I guess this just isn't supported in IE. What else is new?

I had a similar problem, and eventually found that you can get SVG and data URI SVG images working, but some parameters that aren't required for other image types are required for SVG. Specifically, once I size and scaledSize parameters on the definition for the icon (along with uri, origin and anchor values), the error went away and the marker rendered. My sample marker is as follows (with svg having already been defined to be the SVG I want as the marker):

var bubbleImage = {
              url: 'data:image/svg+xml;base64,' + Base64.encode(svg),
              size: new google.maps.Size(192, 21),
              scaledSize: new google.maps.Size(192,21),
              origin: new google.maps.Point(0, 0),
              anchor: new google.maps.Point(88, 53)
          };
          var bubbleMarker = new google.maps.Marker({
              position: feature.position,
              icon: bubbleImage,
              map: window.map,
              optimized: false,
              zIndex: 1
          });
