Lining up tiles and styling

[Ed Dowding]

I'm tiling mapserver tile requests to form a map. On those tiles are lines
styled with a thickness. The lines also have rounded ends.

Which means that when a line goes off the edge of a tile, they're
"rounding-off" making it impossible to tile from separate requests.

Quite difficult to explain, so here's a picture..

One approach would be to get mapserver to draw the line beyond the extent of
its tile... but this is, I think, hypothetical, since I cant see that it's
possible from the docs.


Does anyone have any experience of this?

Thanks in advance,

Ed
