Presentation State

Presentation State (PS) objects serve the following purposes:

Consistent display of images on various devices and media
Storage of specific settings for display (contrast transformations, geometric transformations)
Storage of annotations
Special display of multiframe images

Presentation State objects do not include actual images, but a reference to one or more images.

Presentation State objects, in addition to LUTs, display parameters, and annotations, contain other tags, such as Patient/Study/Series info, Referenced Image UIDs, etc. ImageGear loads all tags from Presentation State object into a metadata tree, which is available to the application.

This section provides information about the following:
