Minimum zoom.
The tile grid origin, i.e. where the x
and y
axes meet ([z, 0, 0]
). Tile coordinates increase left to right and downwards. If not
specified, extent
or origins
must be provided.
Tile grid origins, i.e. where
the x
and y
axes meet ([z, 0, 0]
), for each zoom level. If given, the array length
should match the length of the resolutions
array, i.e. each resolution can have a different
origin. Tile coordinates increase left to right and downwards. If not specified, extent
or
origin
must be provided.
Resolutions. The array index of each resolution needs
to match the zoom level. This means that even if a minZoom
is configured, the resolutions
array will have a length of maxZoom + 1
.
Number of tile rows and columns
of the grid for each zoom level. If specified the values
define each zoom level's extent together with the origin
or origins
.
A grid extent
can be configured in addition, and will further limit the extent
for which tile requests are made by sources. If the bottom-left corner of
an extent is used as origin
or origins
, then the y
value must be
negative because OpenLayers tile coordinates use the top left as the origin.
Tile size.
Default is [256, 256]
.
Tile sizes. If given, the array length
should match the length of the resolutions
array, i.e. each resolution can have a different
tile size.
Generated using TypeDoc
Extent for the tile grid. No tiles outside this extent will be requested by module:ol/source/Tile sources. When no
origin
ororigins
are configured, theorigin
will be set to the top-left corner of the extent.
