OpenLayers tile url function to load tile seeded with TileCache URL scheme

ol-tilecache's Issues

Using ol-tilecache with EPSG:4326 Tiles

The library is really helpful.
I have used custom tilegrids also. It is displaying the map but not the correct tiles. In Zoom 0 it shows only partial map and the tiles seems to be distorted. I am using OL5.
The code snippet is below, Please suggest resolution-
var projection = ol.proj.get('EPSG:4326');
var map_extent=projection.getExtent();
var origin = ol.extent.getTopLeft(projection.getExtent());
var resolution_map= [0.703125, 0.3515625, 0.17578125, 0.087890625,
0.0439453125, 0.02197265625, 0.010986328125,
0.0054931640625, 0.00274658203125, 0.001373291015625, 0.0006866455078125, 0.00034332275390625, 0.000171661376953125,
0.0000858306884765625, 0.00004291534423828125, 0.000021457672119140625,0.000010728836059570,0.000005364418029785];
var tileGrid = new ol.tilegrid.TileGrid({ resolutions: resolution_map,
tileSize: 256,
origin: origin });
var maplayer = new ol.layer.Tile({
source: new ol.source.XYZ({
tileUrlFunction: createTileUrlFunction('https://URL_To_Tilecache/{0z}/{x1}/{x2}/{x3}/{-y1}/{-y2}/{-y3}.jpeg',tileGrid,map_extent)
})
});

Use ol-tilecache with Geoserver

Hi. How to use ol-tilecache with geoserver data?

Upgrade to ol v5

Does it works with custom extent?

HI,

I'm trying to use this plugin to display tiles from Tilecache with ol3 but I the URL generated are not Okay.

The projection of my map is EPSG3943 (http://epsg.io/3943-1753.js)

The resolutions associated to this projection are :
[35.2777777778, 17.6388888889, 8.81944444444, 3.52777777778, 1.76388888889, 0.881944444444, 0.705555555556, 0.352777777778, 0.176388888889, 0.0881944444444]

The extent associated is : 
        extent.xmax=1343422.962875;
        extent.xmin=1335234.08035;
        extent.ymax=2267712.102675;
        extent.ymin=2259212.04695;

and when I try to display my map at [1339328.5216125,2263462.0748125] and zoom level 0, i got
http://myTilecacheServer/myTileset/12/000/002/185/000/002/279.png
instead of
http://myTilecacheServer/myTileset/00/000/000/000/000/000/000.png

I don't see in the code of this plugin any relation with the map extent but in the tilecache.js of OL2 there are in the getUrl :

        var bbox = this.maxExtent;
        ...
        var tileX = Math.round((bounds.left - bbox.left) / (res * size.w));
        var tileY = Math.round((bounds.bottom - bbox.bottom) / (res * size.h));

Does this plugin works only with WorldWide tileset? Or did id do a mistake in my code ?

My code :

       layer=new ol.layer.Tile({
                  source: new ol.source.XYZ({
                      tileUrlFunction: 
                      ol.TileCacheUrlFunction.createTileUrlFunction('http://myTilecacheServer/myTileset/{0z}/{x1}/{x2}/{x3}/{-y1}/{-y2}/{-y3}.png'),
                      projection: 'EPSG:3943'
                  })
              });
        maptest = new ol.Map({
          target: 'map',
          view: new ol.View({
              projection: 'EPSG:3943',
              center: [1339328.5216125,2263462.0748125],
              zoom: 0,
              maxExtent:maxExtent,
              resolutions:resolutions
          }),
          layers: [layer]
      });

Thanks

Rename package

Rename repo and package name to "ol-tilecache" to avoid confusion with a supported version of OpenLayers

Not geting right tiles

Hi,
I tried using this with the v3.9.0 openlayers lib, but the tiles I get are not correct (compared to what I get in ol2).

Ex ol2 gives me http://localhost/tiles/landmass/06/000/000/622/000/000/267.png
but this extn with ol3 gives me tiles like http://localhost/tiles/landmass/06/000/000/044/000/000/035.png

Map center is same in both cases 72.8,18.8 and zoom level 6.

AM I doing something wrong?
