Layer Editor panel - hslayers/hslayers-ng GitHub Wiki

Layer editor is a component in HsLayerManagerModule and is nested under LayerMangerComponent. It lets you edit the currently selected layer from the list provided by layer manager:

• Rename layer
• Set layers dimensions used in WMS, WMTS, XYZ requests through dimension widget.
• Display layers legend using legend widget
• Zoom to layers extent
• Delete layer from map

Several widgets (sub-components) exist to manage/display info about layer and the widget list can be extended using hsLayerEditorWidgetContainerService.

The widgets provided by hslayers-ng are:

• HsTypeWidgetComponent - Displays layer type and service URL if possible
• HsMetadataWidgetComponent - Displays link to metadata and abstract (description) of layer
• HsLegendWidgetComponent - Legend graphics provided by WMS service, hardcoded URL or generated from OL styles in case of vector layer. Uses HsLegendComponent under the hood.
• HsLayerEditorDimensionsComponent - Specify dimensions in the form of dropdowns for lists or datetime pickers for time dimension.
• HsOpacityWidgetComponent - Slider to control opacity of the layer

New widgets can be created by extending HsLayerEditorWidgetBaseComponent class or implementing HsPanelComponent interface and providing your own html template. The widget can be added to the DOM by:

import {HsLayerEditorWidgetContainerService} from 'hslayers-ng/components/layer-manager';
...
this.hsLayerEditorWidgetContainerService.create(
    HsYourWidgetComponent,
    {}
);
