Interface ImageUpdateObserver

All Known Implementing Classes:

SearchImageComparisonModule, SearchImageComparisonModule2

public interface ImageUpdateObserver

Interface declaring methods of a comparison method (module) which can process image updates. For example, the histogram method always needs to process the whole screen even when the tiniest bit of the image changes. The search methods may however limit the search task just to the updated area and its surroundings (depending on the template image size). This makes the algorithms faster and more efficient in situations where they repeatedly search the screen until a particular component appears on or disappears from the screen, for example when employed by the WaitFor command.
