[Paraview-developers] Can the size of SliceAnnotations in the Orthographic Slice View be changed?

[Cory Quammen]

Hi Anton,

You would have to modify the source files
ParaViewCore/ClientServerCore/Rendering/vtkPVOrthographicSliceView.{h,cxx}
to add a public member function that sets the font size. You would have to
forward this to the internal SliceAnnotations list with something like

for (int cc = 0; cc < 3; ++cc)
{

this->SliceAnnotations[cc]->GetTextActor()->SetFontSize(this->AnnotationFontSize);
}

where this->AnnotationFontSize is a new member variable in
vtkPVOrthographicSliceView. After that, you would need to modify

ParaViewCore/ServerManager/SMApplication/Resources/views_and_representations.xml

to expose the new AnnotationFontSize property in the
OrthographicSliceViewProxy entry. This would be a new IntVectorProperty.

Would you be interested in submitting a patch that does this? Instructions
are at

Thanks,
Cory
