[vtkusers] Why the vtkTextProperty.SetFontSize() does not take effect?

[Liu_tj]

Hi, David,


There is no member method GetTextProperty() for vtkCaptionActor2D. No matter how much the font size is, the display is the same. And I found a similar post http://public.kitware.com/pipermail/vtkusers/2004-June/024902.html which is not answered.

Hi,

I use vtkCaptionWidget to display text annotation on 3D model. My issue is the font size of the text. Below is my C# code:

vtkCaptionRepresentation rep = vtkCaptionRepresentation.New();
rep.GetCaptionActor2D().ThreeDimensionalLeaderOff();
rep.GetCaptionActor2D().GetTextActor().GetTextProperty().SetFontSize(100);
rep.GetCaptionActor2D().GetTextActor().GetTextProperty().SetFontFamily(4);
rep.GetCaptionActor2D().GetTextActor().GetTextProperty().SetFontFile("simsunb.ttf");
rep.GetCaptionActor2D().GetCaptionTextProperty().SetColor(0.0, 1.0, 0.0);


Try setting it on rep.GetCaptionActor2D().GetTextProperty() instead of rep.GetCaptionActor2D().GetTextActor().GetTextProperty().
