vtkMRMLAnnotationROINode

Support

I’m looking at this link because my Python scripted module will have 2 or 3 vtkMRMLAnnotationROINode objects open at the same time and I would like them to be distinguishable from each other by line color and/or text label that is visible in the slicer window.
https://apidocs.slicer.org/master/classvtkMRMLAnnotationROINode.html#afaa9522ed4bc6fa5f3234f3787e1c517

What is the correct form of the input for SetLineColor? I tried
r=slicer.vtkMRMLAnnotationROINode()
r.SetLineColor([255,0,0]) and my module just crashed.

Which function of vtkMRMLAnnotationROINode object would allow me to add a label for the ROI that can be seen in the slicer window, and what should its input look like?
SetLabelText didn’t appear to do anything.

Thanks,
Rohan

Review this other forum post - Is possible to change the color of the ROI bounding box from white to something else.

Setting ROI color isn’t a supported thing and fixes to annotation ROI won’t be fixed, but instead ROI objects will be moved into the new Markups module framework.
