[mapserver-users] Rectangle on a map

[Stephen Lime]

It's easy to do. You have to use "inline" features to do this. There are
a couple of steps:

1) create a layer (for example myrect) that holds the symbolization for
the rectangle you want to draw. Notice there is no DATA element.

LAYER
  NAME 'myrect'
  TYPE POLYLINE
  STATUS OFF
  CLASS
    COLOR 255 0 0
  END
END

2) add CGI variables to create a new feature in myrect, add to it and turn
that layer on:

...&map_myrect_feature=new
   &map_myrect_feature_points=x1+y1+x2+y1+x2+y2+x1+y2+x1+y1
   &layer=myrect

That's it.

I'd like to be able to pass a request to a mapserver along with 
four bounding coordinates and have it display a map with a rectangle
on it.  I see this concept applied in the inset map example in some
of the mapserver applications where it makes a .gif file with this
on it. In fact the http://130.11.52.184/global.html does this but
I'm not sure how to translate it to a GET response.

What kind of arguments to the mapserv program would work, or does a
special handler program need to be written?

Doug.
