Class ImageTypeManager

java.lang.Object
  org.apache.myfaces.trinidadinternal.image.ImageTypeManager

public class ImageTypeManager
extends java.lang.Object

ImageTypeManager maintains a set of ImageType objects, each of which defines a type of image component (eg. button, tab bar, etc...) which can be generated (and cached). Each ImageType is identified by a name and namespace. ImageType instances provide the type-specific information needed to generate (and cache) images through a set of properties which can be accessed via the ImageType inteface.

Clients can use the default ImageTypeManager, which can be obtained via the getDefaultImageTypeManager(), or create their own.
