Question

I’m switching icon types of google maps markers between a default one and another one (made by google chart api). To switch back to standard icon I use:

marker.setIcon('http://maps.google.com/mapfiles/marker.png');

For another icon I use:

marker.setIcon('http://maps.google.com/mapfiles/marker_yellow.png');

The question is:

1. is the URL I use really the “standard” (canonical)? Is it assured that google will not change it?

2. it would be better to use some constant like G_DEFAULT_ICON in gmaps api v2. Is there anything similar in api v3?

3. if not, where one can find the list of canonical icon/shadow URLs that are assured to work during all the google api v3 life?

The same question for shadows – when I set the icon, how to get the standard shadow instead of using ugly m.setShadow(new google.maps.MarkerImage('http://maps.gstatic.com/mapfiles/shadow50.png', null, null, new google.maps.Point(10, 34)))? (Note that getShadow() will not tell you anything as it returns null on the default icon with defaultshadow).

PS: there are some dynamic icons APIs but they all are now deprecated, and no remedy has been found.

Answer 1

marker.setIcon(null) will place the default icon with standard shadow…

However, I still miss some “official” list of icons and their URLs, or some constants like G_DEFAULT_ICON to accomplish this.
