问题 I am looking for C or C++ code to identify whether the point (a co-ordinate) lies inside a KML polygon or not. I have searched but all I got is javascript (google maps apis) which can achieve the same. I cannot even port it directly because I have a slight modified requirement: Identify whether given co-ordinate lies within polygon of KML (the code should exclude holes in the polygon too!).

I can only get the last map marker to bounce when i click on it in the list view when its set to marker. I know i

问题 I'm trying to create a page using an custom map type image map as a background. I needed to restrict the panning on the image, so that it's not possible to pan past the image, but when panning the map left / right (along the x / longitude axis), the map disappears and I'm getting a "maximum stack size exceeded" (Chrome) or "too much recursion" (Firefox) error.

Or, I create a polyline by generating
