I’m would like to display unique text in the slice view for each slice.

I’m currently trying to use the python script to display text in slice view:

```
view=slicer.app.layoutManager().threeDWidget(0).threeDView()
# Set text to "Something"
view.cornerAnnotation().SetText(vtk.vtkCornerAnnotation.UpperRight,"Something")
# Set color to red
view.cornerAnnotation().GetTextProperty().SetColor(1,0,0)
# Update the view
view.forceRender()

```

However nothing shows up, do I have to enable something?

Another question I have is would this script display the same text for all the slices? So if I scroll through the slices it would be the same text? How can I display unique text for each slice?

The code above works well for me - displays text in 3D view as expected.

To display text in slice views, replace the first line by this line:

```
view = slicer.app.layoutManager().sliceWidget("Red").sliceView()

```

You may consider hiding slice view annotations, to prevent them from overwriting the text you place there. See [example](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Hide_slice_view_annotations_.28DataProbe.29).

Yes, sure, see how the text is scaled by DataProbe:
