In my Winforms application, I am painting 2D shapes.
Where i click, I want to fill the surrounding shape (or region in case of intersection of shapes). How can I get the region surrounding a point?
Thanks in advance.

You can compose a region from a set of 'shapes', lines, points or rectangles. – leppie Dec 07 '12 at 06:29

Check this for intersection with polygons: http://stackoverflow.com/questions/217578/point-in-polygon-aka-hit-test. For finding shapes around the point, you can simply find all shapes which points or origin are within a specific distance from your point – rro Dec 07 '12 at 07:12
