public interface IGeoImageDescription
extends Serializable

Provides access to members that control an image description.

Description

This interface is new at ArcGIS 9.3.

Remarks

IGeoImageDescription provides the access to define the properties of an image you would like to retrieve from an image server. The pixel data will be processed on-the-fly to fit your description and returned. The properties you can specify include extent, spatial reference, compression, interpolation, band selection, etc.
