*

* To create a a new KaMapCache layer, you must indicate also the "i" parameter
|
||||
* (that will be used to calculate the file extension), and another special
|
||||
* parameter, object names "metaTileSize", with "h" (height) and "w" (width)
|
||||
* properties.

||||
*
|
||||
* // Create a new kaMapCache layer.
|

* var kamap_base = new OpenLayers.Layer.KaMapCache(
|

* "Satellite",

|
||||
* {g: "satellite", map: "world", i: 'png24', metaTileSize: {w: 5, h: 5} }

|

|

* var/cache/World/50000/Group_Name/def/t-440320/l20480
|
||||
*
|
||||
* This means that the cache generated via tile.php will *not* work with
|
||||
* this class, and should instead use the KaMap layer.
