ILayer2 Interface

Provides access to additional members that work with all layers.

Product Availability

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

Description

ILayer2 is a generic interface for all layer objects. This interface has a method to draw the layer and provides access to generic layer properties. This interface adds to what is supported by ILayer by adding a property that indicates whether or not the scale range properties are read only and a property that lets you set the layer's area of interest.

Members

Name Description
Write-only property AreaOfInterest The default area of interest for the layer.
Read-only property AreaOfInterest The default area of interest for the layer.
Read/write property Cached Indicates if the layer needs its own display cache.
Method Draw Draws the layer to the specified display for the given draw phase.
Read/write property MaximumScale Maximum scale (representative fraction) at which the layer will display.
Read/write property MinimumScale Minimum scale (representative fraction) at which the layer will display.
Read/write property Name Layer name.
Read-only property ScaleRangeReadOnly Indicates if the minimum and maximum scale range values are read-only.
Read/write property ShowTips Indicates if the layer shows map tips.
Write-only property SpatialReference Spatial reference for the layer.
Read-only property SupportedDrawPhases Supported draw phases.
Read-only property TipText Map tip text at the specified location.
Read-only property Valid Indicates if the layer is currently valid.
Read/write property Visible Indicates if the layer is currently visible.
