nope. at least i am not aware of any modified tile.php. life and need
put me to do this hack on setTile. the big challange was (for me) to
put azScales to match kaMap.<br>
<br>
kaMap display engine is fast and simple. nothing fancy, but very
functional. this is why i will use it as a starting point for
displaying tiles in my projects. so, if i can hack into the js code of
kaMap, why use tile.php? ... or openlayers ...<br>
<br>
this could become a layer such as wmslayer ... maybe sometime when i
have time or maybe someone else could do this ;)<br>

<pre wrap="">very cool. has anyone modified tile.php so it can accept x/y/z parameters instead of the top/left/scale parameters? then tile.php could be used instead of TileCache which is written in Python instead of PHP.

kaMap - setTile function - uses
openstreetmap servers.
File that replaces init.php. Paste the code below in a file
on your
server and load it at run time instead of init.php.

Replace setTile with the function below.
_layer.prototype.setTile = function(img) {
var tforce = _settings.alwaysForceDraw;
if (arguments.length == 2)
tforce = true;
var mercExtents = new
Array('-20037508.34', '20037508.34');
var zIdx = (this._map.currentScale + 2);
// osm zooms are from 0 to
18. azScales contains only calculated scales from 2 to 18
...
var res = this._map.resolutions[zIdx];
var km = this._map.kaMap;
var left = km.cellSize *
(safeParseInt(img.style.left) + km.xOrigin);
var top = -1 * km.cellSize *
(safeParseInt(img.style.top) + km.yOrigin);
var right = left + km.cellSize *
km.tileWidth;
var bottom = top - km.cellSize *
km.tileHeight;
if (left < mercExtents[0] || left >
mercExtents[2] || top <
mercExtents[0] || top > mercExtents[1]) return false;
var limit = Math.pow(2, zIdx);
var x = Math.round((left -
mercExtents[0]) / (res * km.tileWidth));
var y = Math.round((mercExtents[1] - top)
/ (res * km.tileHeight));
if (y < 0 || y >= limit) return
false;
x = ((x % limit) + limit) % limit;
if (tforce) {
var src = this._map.kaMap.tileURL +
zIdx + '/' + x + '/' + y + '.png';
} else {
var src = this._map.kaMap.cacheURL +
zIdx + '/' + x + '/' + y +
'.png';
}
if (img.src != src) {
img.style.visibility =
'hidden';
img.src = src;
}
};
Have fun!
