ILayer Interface

Provides access to members that work with all layers. Note: the ILayer interface has been superseded by ILayer2. Please consider using the more recent version.

Product Availability

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

Description

ILayer is a generic interface for all layer objects. This interface has a method to draw the layer and provides access to generic layer properties.

Members

Description
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/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.

Remarks

This interface has a method to draw the layer and properties to define the minimum and maximum display scales, the spatial reference, the name, layer visibility, whether or not the layer is cached, and whether or not the layer shows map tips.

There are also properties that indicate whether the layer is valid, its supported draw phases, area of interest, and the map tip text for a given coordinate.
