Class RasterImageLayer

Applies the visitor to this layer.

Returns the layer with the given ID if that layer is this node or one of its children. Note that the layer's ID does not correspond with the layer's label.

Returns the layer group with the given ID if that layer is this node or one of its children.

Returns the layer tree node with the given ID if that layer is this node or one of its children. This may be a layer-group or a layer.

Returns the area of the map that is currently visible, expressed in model coordinates.

Indicates whether the specified paint representation is supported for this layer. Not every LayerTreeNode may support all paint representations. E.g. raster layers may not b have a PaintRepresentation.LABEL paint representation.

Indicates whether the specified paint representation is visible.

Indicates whether the specified paint representation is visible on the map. This method will only return true if this paint representation is visible for this layer and every parent layer up to the layer tree.

Called when the map has detected a single click on an object that is contained by this layer. This method can be overridden to take action when the click is detected. The default implementation of this method simply returns false.

Called when the map is going to display a context menu for an object that is contained by this layer. This method can be overridden to populate the given context menu with additional items.

Sets the visibility of a specific paint representation. This allows for example to only show the PaintRepresentation.BODY of a layer and not the PaintRepresentation.LABEL:

  var layer = ...;
  layer.setPaintRepresentationVisible( PaintRepresentation.BODY, true );
  layer.setPaintRepresentationVisible( PaintRepresentation.LABEL, false );
Copy

Sets the visibility of a specific paint representation in a layer tree. If it set to true, this will ensure that the paint representation of every parent LayerTreeNode up to the roof of the tree is configured to be visible as well.

Accepts the given visitor on the children of this.

Wait until this layer or layer group is finished with all possible work related to any change that happened before this call.
At that moment, the screen is up-to-date with all changes.

Examples:

  map.mapNavigator.fit({ bounds: somewhere });
  map.layerTree.whenReady().then(makeScreenshot);
Copy

or

    layer.painter.invalidateAll();
    layer.whenReady().then(alert);
Copy

or

    layer.model.add(newFeature);
    layer.whenReady().then(alert);
Copy

This call can be used to have a reliable, programmatic way to wait for all work leading up to the call to be reflected on the screen.
The returned promise will always resolve once, when the layer is ready. The promise is rejected when the layer does not become ready in 5 minutes.

Examples (not exhaustive) of aspects this promise will wait for:

• While loading image data when it displayed for the first time, or after navigating the view
• While loading image data after changing raster model properties such as WMS style
• While loading feature data when it displayed for the first time, enters its scale range, or after navigating the view
• While loading feature data after invalidating the layer query provider
• While processing features after invalidating the layer feature painter or shape provider, or changing the layer filter
• While processing features after they were added, updated or removed to/in/from a model or workingSet

NOTE: The promise gets resolved also when an error (QueryStatus.QUERY_ERROR) occurs while handling underlying query or when the node is invisible.

A LayerTree will wait until all its children are ready.

Registers a callback function for a given event type.

Event fired when the editability of the layer changes.
