What you are asking for is client side image sampling for image displayed in a browser. It's not a maps question, so you might find something if you search in more general terms ... but I think the answer is "no".
If the images are being "created" e.g. drawing a line of a certain colour then you could access the data used to do the creating (such as parsing it out of KML) If you want some kind of interactivity with a bar chart image or whatever that you are creating server-side, you might use traditional HTML methods and also create an image map server-side that the client can use to select areas. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
