Methods
-
getMaxZoom(){number} experimental
src/ol/tilegrid/tilegrid.js, line 190 -
Get the maximum zoom level for the grid.
Returns:
Max zoom.
-
getMinZoom(){number} experimental
src/ol/tilegrid/tilegrid.js, line 200 -
Get the minimum zoom level for the grid.
Returns:
Min zoom.
-
getOrigin(z){ol.Coordinate}
src/ol/tilegrid/tilegrid.js, line 211 -
Get the origin for the grid at the given zoom level.
Name Type Description z
number Z.
Returns:
Origin.
-
getResolution(z){number}
src/ol/tilegrid/tilegrid.js, line 231 -
Get the resolution for the given zoom level.
Name Type Description z
number Z.
Returns:
Resolution.
-
getResolutions(){Array.<number>}
src/ol/tilegrid/tilegrid.js, line 244 -
Get the list of resolutions for the tile grid.
Returns:
Resolutions.
-
getTileCoordExtent(tileCoord, opt_extent){ol.Extent} experimental
src/ol/tilegrid/tilegrid.js, line 339 -
Get the extent of a tile coordinate.
Name Type Description tileCoord
ol.TileCoord Tile coordinate.
extent
ol.Extent Temporary extent object.
Returns:
Extent.
-
getTileCoordForCoordAndResolution(coordinate, resolution, opt_tileCoord){ol.TileCoord} experimental
src/ol/tilegrid/tilegrid.js, line 362 -
Get the tile coordinate for the given map coordinate and resolution. This method considers that coordinates that intersect tile boundaries should be assigned the higher tile coordinate.
Name Type Description coordinate
ol.Coordinate Coordinate.
resolution
number Resolution.
tileCoord
ol.TileCoord Destination ol.TileCoord object.
Returns:
Tile coordinate.
-
getTileCoordForCoordAndZ(coordinate, z, opt_tileCoord){ol.TileCoord} experimental
src/ol/tilegrid/tilegrid.js, line 413 -
Get a tile coordinate given a map coordinate and zoom level.
Name Type Description coordinate
ol.Coordinate Coordinate.
z
number Zoom level.
tileCoord
ol.TileCoord Destination ol.TileCoord object.
Returns:
Tile coordinate.
-
getTileSize(z){number|ol.Size}
src/ol/tilegrid/tilegrid.js, line 441 -
Get the tile size for a zoom level. The type of the return value matches the
tileSize
ortileSizes
that the tile grid was configured with. To always get anol.Size
, run the result throughol.size.toSize()
.Name Type Description z
number Z.
Returns:
Tile size.
