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

CoClasses that implement ILayer

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.
