[mapguide-users] Partial polygons closed at map viewer edges

[Maksim Sestic]

That's something I also noticed long time ago :-) The solution would be to
render a map 1 px wider, and to cut it for that 1 extra pixel via JavaScript
while displaying in browser. Yes, it represents unaccurate map rendering -
people are always thinking that there's a polygon border where it, actually,
isn't.

Another funny thing is how dynamic labels behave near map edges - they get
shrunk. Although this may seem handy, it's also inacurrate in cartographic
sense. Dynamic labels near edges should be displayed as any other dynamic
label (should get cut if exceed the display limits).

Subject: [mapguide-users] Partial polygons closed at map viewer edges


Hello 

When viewing a polygon in MGOS, if one is zoomed in so that some of the
polygon is off-screen, MGOS clips the border along the edges of the viewer.
To see what I mean, see:

http://maps.northumberlandnationalpark.org.uk:443/
http://maps.northumberlandnationalpark.org.uk:443/ 

Zoom in within the navy line which is our boundary, and see its behaviour
once some of the line is off-screen: it runs along the edge of the map,
despite the fact that the true border is not there, but off-screen.

Is there any reason for this behaviour? To me, it represents inaccurate
rendering of data.

Thanks

Tom
