java.lang.Object
- org.scijava.AbstractContextual
- - org.scijava.module.process.AbstractPreprocessorPlugin
  - - net.imagej.display.process.SingleInputPreprocessor<Overlay>
    - - net.imagej.display.process.ActiveOverlayPreprocessor

All Implemented Interfaces:

Cancelable, Contextual, ModulePreprocessor, ModuleProcessor, PreprocessorPlugin, SciJavaPlugin
```
public class ActiveOverlayPreprocessor
extends SingleInputPreprocessor<Overlay>
```
Assigns the Overlay of the active ImageDisplay when there is one single unresolved Overlay parameter. Hence, rather than a dialog prompting the user to choose an ImageDisplay, the Overlay of the active ImageDisplay is used automatically.
In the case of more than one Overlay parameter, the active Overlay is not used and instead the user must select. This behavior is consistent with ImageJ v1.x.
