15  """ Abstract scripted segment editor label effects for effects implemented in python
16 
17  USAGE:
18  1. Instantiation and registration
19  Instantiate segment editor label effect adaptor class from
20  module (e.g. from setup function), and set python source:
21  > import qSlicerSegmentationsEditorEffectsPythonQt as effects
22  > scriptedEffect = effects.qSlicerSegmentEditorScriptedLabelEffect(None)
23  > scriptedEffect.setPythonSource(MyLabelEffect.filePath)
24  Registration is automatic
25 
26  2. Call host C++ implementation using
27  > self.scriptedEffect.functionName()
28 
29  2.a. Most frequently used such methods are:
30  Parameter get/set: parameter, integerParameter, doubleParameter, setParameter
31  Add options widget: addOptionsWidget
32  Coordinate transforms: rasToXy, xyzToRas, xyToRas, xyzToIjk, xyToIjk
33  Convenience getters: renderWindow, renderer, viewNode
34  Geometry getters: imageToWorldMatrix (for volume node and for oriented image data with segmentation)
35 
36  2.b. Always call API functions (the ones that are defined in the adaptor
37  class qSlicerSegmentEditorScriptedLabelEffect) using the adaptor accessor:
38  > self.scriptedEffect.updateGUIFromMRML()
39 
40  An example for a generic effect is the DrawEffect
