Chapter 7. Background Tasks

The Background Tasks View displays running background tasks.

ML Background Tasks is a framework for executing long-computing tasks in worker threads. The basic framework is independent of the ML; however, convenience classes add access to ML images. For more information on background tasks, see the ToolBox Reference, chapter “Background Tasks”.

Background tasks are implemented for some modules, for example, GVRVolumeSave, GVRImageToVolume and ImageSave. For other modules, check whether their panels provide features such as “Save in Background”.
