It seems to me like the box handler returns a set of pixels describing<BR>
the box, and that the code added gets the coordinates for this.<BR>
<BR>
I guess a simlpe approach is the use the coordinates and construct a<BR>
polygon geometry and then add this as a feature to a vector layer on the<BR>
map, and then apply a style to make it look like the box.<BR>
