# Abstract class of python scripted segment editor label effects
#
# Label effects are a subtype of general effects that edit the currently selected
# segment (i.e. for things like paint or draw, but not for things like threshold)

class AbstractScriptedSegmentEditorLabelEffect(AbstractScriptedSegmentEditorEffect):
  """ Abstract scripted segment editor label effects for effects implemented in python

      USAGE:
      1. Instantiation and registration
        Instantiate segment editor label effect adaptor class from
        module (e.g. from setup function), and set python source:
        > import qSlicerSegmentationsEditorEffectsPythonQt as effects
        > scriptedEffect = effects.qSlicerSegmentEditorScriptedLabelEffect(None)
        > scriptedEffect.setPythonSource(MyLabelEffect.filePath)
        Registration is automatic

      2. Call host C++ implementation using
        > self.scriptedEffect.functionName()

      2.a. Most frequently used such methods are:
        Parameter get/set: parameter, integerParameter, doubleParameter, setParameter
        Add options widget: addOptionsWidget
        Coordinate transforms: rasToXy, xyzToRas, xyToRas, xyzToIjk, xyToIjk
        Convenience getters: renderWindow, renderer, viewNode
        Geometry getters: imageToWorldMatrix (for volume node and for oriented image data with segmentation)

      2.b. Always call API functions (the ones that are defined in the adaptor
        class qSlicerSegmentEditorScriptedLabelEffect) using the adaptor accessor:
        > self.scriptedEffect.updateGUIFromMRML()

      An example for a generic effect is the DrawEffect
