[ka-Map-users] kaXmlOverlay performance problem

[Tamas Szekeres]

Hi list,

The current implementation of rendering linestrings and polygons use
the drawgeom.php (AFAIK).
The size of the generated overlay image highly depends on the current
scale of the map. When zooming in the image size may be extremely
large that increases the download time and the memory usage of the
browser.

I think this type of the overlay rendering should be reconsidered so
as drawgeom should render only a smaller visible segment of the image
and a new drawing request should be submitted when the user recenters
the map outside of that image area.

Any comments would be appreciated.

Best Regards,
