Class: TileDebug

ol/source/TileDebug~TileDebug


import TileDebug from 'ol/source/TileDebug';

A pseudo tile source, which does not fetch tiles from a server, but renders a grid outline for the tile grid/projection along with the coordinates for each tile. See examples/canvas-tiles for an example.

new TileDebug(opt_options)

Name Type Description
options

Debug tile options.

Name Type Description
projection module:ol/proj~ProjectionLike (defaults to 'EPSG:3857')

Optional projection.

tileGrid module:ol/tilegrid/TileGrid~TileGrid

Tile grid.

wrapX boolean (defaults to true)

Whether to wrap the world horizontally.

zDirection number | module:ol/array~NearestDirectionFunction (defaults to 0)

Set to 1 when debugging VectorTile sources with a default configuration. Choose whether to use tiles with a higher or lower zoom level when between integer zoom levels. See module:ol/tilegrid/TileGrid~TileGrid#getZForResolution.

template string (defaults to 'z:{z} x:{x} y:{y}')

Template for labeling the tiles. Should include {x}, {y} or {-y}, and {z} placeholders.

Fires:

Extends

Methods

Increases the revision counter and dispatches a 'change' event.

Remove all cached tiles from the source. The next render cycle will fetch new tiles.

dispatchEvent(event){boolean|undefined} inherited

Dispatches an event and calls all listeners listening for events of this type. The event parameter can either be a string or an Object with a type property.

key string

Key name.

Returns:
Value.

Get the attribution function for the source.

Returns:
Attribution function.

getAttributionsCollapsible(){boolean} inherited

Returns:
Attributions are collapsible.

getKeys(){Array.<string>} inherited

Get a list of object property names.

Returns:
List of property names.

Get the projection of the source.

Returns:
Projection.

getProperties(){Object.<string, *>} inherited

Get an object of all property names and values.

Returns:
Object.

getRevision(){number} inherited

Get the version number for this object. Each time the object is modified, its version number will be incremented.

Returns:
Revision.

Get the state of the source, see module:ol/source/State~State for possible states.

Returns:
State.

Return the tile grid of the tile source.

Returns:
Tile grid.

Return the tile load function of the source.

Returns:
TileLoadFunction

Return the tile URL function of the source.

Returns:

Returns:
URLs.

Listen for a certain type of event.

Name Type Description
type string | Array.<string>

The event type or array of event types.

listener function

The listener function.

Listen once for a certain type of event.

Name Type Description
type string | Array.<string>

The event type or array of event types.

listener function

The listener function.

Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.

Refreshes the source. The source will be cleared, and data from the server will be reloaded.

set(key, value, opt_silent) inherited

Sets a value.

Name Type Description
key string

Key name.

value *

Value.

silent boolean

Update without triggering an event.

setAttributions(attributions) inherited

Set the attributions of the source.

setTileGridForProjection(projection, tilegrid) inherited

Sets the tile grid to use when reprojecting the tiles to the given projection instead of the default tile grid for the projection.

This can be useful when the default tile grid cannot be created (e.g. projection has no extent defined) or for optimization reasons (custom tile size, resolutions, ...).

Name Type Description
projection module:ol/proj~ProjectionLike

Projection.

tilegrid module:ol/tilegrid/TileGrid~TileGrid
