[OpenLayers-Users] tile images and leading zeros

[Xin]

Thank you for the quick reply Chris. It helped a lot.

I am new to this and wasn't sure how to use tiles. So I searched for tiles
on the example page, and TileCache came up. That's how I got to use it!

Using http://trac.openlayers.org/wiki/UsingCustomTiles, OL is accessing
tiles in the right format now. But the exact file name does not match with
what I produced from a certain bounding box and zoom range. I fear it's
projection issues.

My updated JS:
http://pastie.caboo.se/158268

As you can see, I have set the options for Google-like tiles.

My generate_tiles.py configs:
    minZoom = 10
    maxZoom = 16
    bbox = (16.981109375,-22.6169453125,17.156890625,-22.5290546875)
    render_tiles(bbox, mapfile, tile_dir, minZoom, maxZoom)

The lat/lng from JS and bbox from generate_tiles are of the same place.

At default zoom (14), some of the tiles OL's looking for are:
http://localhost:3000/tiles/14/8193/8188.png
http://localhost:3000/tiles/14/8192/8188.png
http://localhost:3000/tiles/14/8191/8188.png
http://localhost:3000/tiles/14/8190/8188.png
http://localhost:3000/tiles/14/8189/8188.png

listing directory 14:
8964  8965  8966  8967  8968  8969  8970  8971  8972

It's so close! but not quite it. Can anyone offer any advice?

Any help is much appreciated.

Xin
