I'm trying to add the OverviewMap control to a map built with KaMap layers.
I'm using OL version 2.4. The example - examples\overviewmap.html - works perfectly. Mine doesn't work at all. When the OverviewMap control requests tiles from KaMap, the tiles are generated correctly - or at least they seem to. The directory structure looks fine, and the generated GIF files look fine. But the tiles that are actually being requested don't correspond to any of the tiles that were generated. The URL of the tile that was requested: http://localhost:8080/servicearealookup/tile.php?map=mississippi&g=all&i =gif&t=-768&l=-1536&s=19686393 Top is -768, left is -1536, scale is 19686393. In the KaMap cache, there is a directory for scale 19686393, and in that a subdirectory for group "all", and for layer "def". And in that, there is a subdirectory t-1200l-2400. In that, there are 36 GIF files, all of them blank except one, t-600l-1600.gif, which contains the image that should be being drawn in the overview map at this scale. (Zoomed out all the way.) Now I seem to remember having had a similar problem with KaMap on the main map, because the default tile size in OpenLayers was 256x256 and in KaMap was 200x200. Which I fixed by setting the tilesize option to the OpenLayers.Map constructor. So I passed a tilesize option to the OverviewMap constructor, and it made no difference. Has anyone had any experience with the OverviewMap on KaMap layers? _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
