Hi,

I’d like to create a button in my extension that merges all the segmentations in the image.

I found this: [Slicer: vtkSegmentation Class Reference](https://apidocs.slicer.org/master/classvtkSegmentation.html#a9498f59bcdf034585209f4bf79b76357)

Where I see that I can use GenerateMergedLabelmap() and GenerateMergedLabelmapForAllSegments(), but I’m unsure how to use it. Can anyone help?
