Google maps API: Marker image positioning

阅读更多关于 Google maps API: Marker image positioning

问题 I have changed the image that I use for a marker on Google maps. The new image is much wider than the old one and I have noticed that the marker is aligned with the lat and lng so that the marker rests with it's horizontal midpoint over the lat and lng . This is not what I want, I want to have the lat and lng aligned with the markers left hand side - I want to offset the marker from the default position by about 80px to the right. 回答1: Try this on for size. var markerImage = new google.maps
