Summary	0004332: vtkMRMLAnnotationROINode collapses the Radius to zero when hardening the transform
Description	When Hardening the transform, the radius of vtkMRMLAnnotationROINode collapses to 0. Attached is the code to reproduce the error.
Steps To Reproduce	import slicer ROINode = slicer.vtkMRMLAnnotationROINode() ROINode.SetName('ROINode') ROINode.SetXYZ((20,20,20)) ROINode.SetRadiusXYZ((10,10,10)) slicer.mrmlScene.AddNode(ROINode) ROINode.UpdateScene(slicer.mrmlScene) ROITransformNode = slicer.vtkMRMLTransformNode() ROITransformNode.SetName('ROITransformNode') transform = vtk.vtkTransform() transform.Translate((10,20,30)) ROITransformNode.SetAndObserveTransformToParent(transform) slicer.mrmlScene.AddNode(ROITransformNode) center1 = [0]3 ROINode.GetXYZ(center1) radius1 = [0]3 ROINode.GetRadiusXYZ(radius1) ROINode.SetAndObserveTransformNodeID(ROITransformNode.GetID()) logic = slicer.vtkSlicerTransformLogic() logic.hardenTransform(ROINode) center2 = [0]3 ROINode.GetXYZ(center2) radius2 = [0]3 ROINode.GetRadiusXYZ(radius2) print( center1, center2 ) print( radius1, radius2 )
