com.ibm.workplace.wcm.api
Interface ImageComponent

All Superinterfaces:

ContentComponent, DigitalAsset, RenditionCapability, Resource, WCMApiObject

public interface ImageComponent
extends ContentComponent, DigitalAsset, Resource, RenditionCapability

Represents an Image component.

A ImageComponent is a ContentComponent and cannot be stored as a separate entity in the repository.

A ImageComponent can contain one image. The contents of the image file are dealt with as raw byte content. This interface provides methods to manipulate the image file and the attributes to use when displaying the image.

note: since v6.0.0, a ImageComponent is referred to as an "Image Element" in the Authoring UI.
