Finding the lat-long of the corners in a Google Ma

Question

Using the Google Maps API, how can I get the latitude and longitude of the corners of the map display area?

That is, if my map is 300px wide and 400px tall, how can I find the lat-long of the points at (0,0) and (300,400)?

Answer 1

Use getBounds(). From the doc:

Returns the the visible rectangular region of the map view in geographical coordinates.

That function returns exactly what you want: the southwest and northeast corners of your map. The first pair of coordinates are the lower left (southwest) coordinates and the second pair is the upper right (northeast) coordinates.
