Class RenderingHintsPreviewImage

  • public class RenderingHintsPreviewImage
extends Object
    Contains hints for rendering a preview image, e.g. in a webpage as HTML.
    These are related to an ImageFileResource but there may exist more than one rendering hints container, each per individual use case.
    This makes it possible to use/embed an image in several projects and locations, each time rendered individually.
    The rendering hints therefore are kept separate in an own rendering hints object and have to be stored in conjunction with each specific use case.

    Example:
    A person object has a portrait photo as preview image. On the detail page of this person (= use case) specific caption and link are defined.
    So at the person storage an ImageFileResource is defined as preview image and individual filled rendering hints are stored beside at the person object (and not "centrally" at the reusable ImageFileResource).

    This makes it possible to reuse an image in different use cases but with individual alt-text, caption, (mouseover) title and link.
