Constructors
LabelGenerator(AuthenticationManager, JsModuleManager, IAppValidator, IJSRuntime) Constructor
Constructor for use by Dependency Injection. Use AddGeoBlazorPro(this IServiceCollection, IConfiguration) in your startup code.
public LabelGenerator(dymaptic.GeoBlazor.Core.Model.AuthenticationManager authenticationManager, dymaptic.GeoBlazor.Core.JsModuleManager jsModuleManager, dymaptic.GeoBlazor.Core.IAppValidator appValidator, Microsoft.JSInterop.IJSRuntime jsRuntime);
Parameters
authenticationManager dymaptic.GeoBlazor.Core.Model.AuthenticationManager
jsModuleManager dymaptic.GeoBlazor.Core.JsModuleManager
appValidator dymaptic.GeoBlazor.Core.IAppValidator
jsRuntime Microsoft.JSInterop.IJSRuntime
Methods
LabelGenerator.GetBinLabelSchemes(Layer, string, Renderer) Method
The renderer to set on the input layer when clustering is enabled. Specify this parameter if the layer’s renderer does not match the renderer that will be used when clustering is enabled. This cannot be a HeatmapRenderer.
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Pro.Model.LabelSchemes> GetBinLabelSchemes(dymaptic.GeoBlazor.Core.Components.Layers.Layer layer, string? field=null, dymaptic.GeoBlazor.Core.Components.Renderers.Renderer? renderer=null);
Parameters
layer dymaptic.GeoBlazor.Core.Components.Layers.Layer
The view where the input layer will be rendered.
field System.String
The name of the AggregateField to use in the primary label scheme. If not specified, then the label will be based on the aggregate count field.
renderer dymaptic.GeoBlazor.Core.Components.Renderers.Renderer
The renderer to set on layer.featureReduction.renderer when binning is enabled.
Returns
System.Threading.Tasks.Task<LabelSchemes>
LabelGenerator.GetClusterLabelSchemes(Layer, Guid, string, Renderer) Method
Generates default labelingInfo schemes to be set on a FeatureLayer’s featureReduction configuration. Returns one or more suggested LabelClasses for a given layer based on its renderer. It also returns a suggested clusterMinSize to ensure labels fit inside clusters.
If a renderer has a non-scale dependent SizeVariable, then the average value of the field or expression used to determine the cluster size will be suggested as the default label value. In all other scenarios, the suggested label will display the cluster count in the center of the label.
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Pro.Model.LabelSchemes> GetClusterLabelSchemes(dymaptic.GeoBlazor.Core.Components.Layers.Layer layer, System.Guid viewId, string? field=null, dymaptic.GeoBlazor.Core.Components.Renderers.Renderer? renderer=null);
Parameters
layer dymaptic.GeoBlazor.Core.Components.Layers.Layer
The point layer that has or will have clustering enabled.
viewId System.Guid
The Id for the view where the input layer will be rendered.
field System.String
The name of the AggregateField to use in the primary label scheme. If not specified, then the label will be based on the data used to vary cluster size.
renderer dymaptic.GeoBlazor.Core.Components.Renderers.Renderer
The renderer to set on the input layer when clustering is enabled. Specify this parameter if the layer’s renderer does not match the renderer that will be used when clustering is enabled. This cannot be a HeatmapRenderer.
