SV: find spot within polygon

Hi Chris,
There are a method DrawUtil.inside_polygon that does this.
(com.bbn.openmap.proj.
<file:///D:/openmap/openmap-4.4.2/doc/api/com/bbn/openmap/proj/DrawUtil.html
> DrawUtil ):
I could not really get it to work correctly (dont know why).
 
So I used java.awt.Polygon.
<http://java.sun.com/j2se/1.3/docs/api/java/awt/Polygon.html#contains(int,
int)> contains(int x, int y)

Ämne: find spot within polygon

Hello,

I am looking for an algorithm to check if a certain point is within a
closed polygon or not. I have searched the Openmap classes, but have not
found anything that looks like that. Have I missed it?

It does not seem easy to me, as the polygon can be any shape (basically
following esri´s rules). Does anyone have a hint for me?

Thanks,
Chris van Lith
