hi list!
I have a map in which i dont know how will I able to identify the region when
I click a hot spot on it. I have attached here in how my map looks. I don't
want to use an ordinary image map method because it would be tedious to
manually do it. I understand that if i click a point in the image i could get
a point in pixels,my problem is how will I know if that point lies inside a
particular province,in my case,considering all I know about the provinces are
their extents in georeference,is there some way of knowing the pixel boundary
of a certain region in the image without using imagemap. Another thing that I
would like to know is that how will I be able to generate a tooltip on
mouseover when the mouse goes on top of a paricular province,is there a way
without using javascript but purely mapscript? all responses will be
appreciated much..thx
