IBasicOverposterLayerProperties3 Interface

Provides access to members that control the placement of labels relative to features using conflict detection.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Manages settings that control the placement of dynamic labels and feature-linked annotation relative to features. This interface manages generic settings that apply to all feature geometry types (point, line, and polygon). This interface also manages, or provides access to other objects that manage, placement properties that are used only when labeling or annotating a specific feature geometry type.

Members

	FeatureType	Feature type.
	FeatureWeight	Barrier weighting for features in the layer.
	GenerateUnplacedLabels	Indicates if unplaced labels are generated.
	LabelWeight	Barrier weighting for labels in the layer.
	LineLabelPlacementPriorities	Line label placement position priority options.
	LineLabelPosition	Line label placement position options.
	LineOffset	Offset in map units at which labels will be placed away from line features.
	MaxDistanceFromTarget	Maximum distance in map units the label is allowed to be away from the feature.
	NumLabelsOption	Feature labeling option for the layer.
	PerpendicularToAngle	Indicates whether the label should be drawn perpendicular to the angle.
	PointPlacementAngles	Point label placement angle(s).
	PointPlacementMethod	Point label placement method.
	PointPlacementOnTop	Indicates if point labels are placed on top of features.
	PointPlacementPriorities	Point label placement position priority options.
	RotationField	The attribute field that contains the label angle.
	RotationType	Defines the format is the rotation field in.

The following example is a code excerpt that shows how to get a reference to a layer's IBasicOverposterLayerProperties3 in an ArcMap VBA session.
  Dim pMxDoc As IMxDocument
  Set pMxDoc = ThisDocument
  Dim pFL As IFeatureLayer
  Set pFL = pMxDoc.ActiveView.FocusMap.Layer(0)
    
  'get AnnotateLayerPropertiesCollection from GeoFeatureLayer
  Dim pGeoFL As IGeoFeatureLayer
  Set pGeoFL = pFL
  Dim pAnnoLayerPropsColl As IAnnotateLayerPropertiesCollection
  Set pAnnoLayerPropsColl = pGeoFL.AnnotationProperties
    
  'get the (first) AnnotateLayerProperties property set in the collection
  Dim pAnnoLayerProps As IAnnotateLayerProperties
  pAnnoLayerPropsColl.QueryItem 0, pAnnoLayerProps, Nothing, Nothing
    
  'get the LabelEngineLayerProperties
  Dim pLabelEngineLayerProps As ILabelEngineLayerProperties
  Set pLabelEngineLayerProps = pAnnoLayerProps
        
  'get the BasicOverposterLayerProperties
  Dim pBasicOverposterLayerProps3 As IBasicOverposterLayerProperties3
  Set pBasicOverposterLayerProps3 = pLabelEngineLayerProps.BasicOverposterLayerProperties
    
  MsgBox pBasicOverposterLayerProps3.BufferRatio
