RegionOfInterest

Purpose

This module defines a typed event for broadcasting changes to a Region of Interest (ROI) within the application. It leverages the Prism event aggregation system to enable loosely-coupled communication between components when ROI configuration changes, allowing subscribers to react to new ROI definitions without direct coupling to the publisher.

Public Interface

RegionOfInterestChangedEvent

• Signature: public class RegionOfInterestChangedEvent : PubSubEvent<IRegionOfInterest>
• Description: A Prism PubSubEvent that carries an IRegionOfInterest payload. Publishers invoke this event with a new ROI instance; subscribers receive the IRegionOfInterest object when the event is published.

Invariants

• The event payload must implement IRegionOfInterest (defined in DTS.Common.Interface.RegionOfInterest).
• As a PubSubEvent<T>, the event follows Prism's thread-safe publication/subscription semantics.

Dependencies

• Depends on: Prism.Events (for PubSubEvent<T> base class), DTS.Common.Interface.RegionOfInterest (for IRegionOfInterest interface).
• Depended on by: Not determinable from source alone; consumers would subscribe to or publish this event via Prism's IEventAggregator.

Gotchas

None identified from source alone.
