<div>Hi, VTK guys,<br><br>When I display a vtkCaptionWidget, I want to set the position of the text. So I call the vtkActor2D:;SetPostion() and SetPosition2(), but when the widget is displayed, the text is alway at the left bottom corner, why? Below is my C# code:<br><br>vtkCaptionRepresentation rep = vtkCaptionRepresentation.New();<br>rep.GetCaptionActor2D().ThreeDimensionalLeaderOff();<br>            <br>rep.GetCaptionActor2D().GetTextActor().SetTextScaleModeToNone();<br>rep.GetCaptionActor2D().GetCaptionTextProperty().SetColor(0.0, 1.0, 0.0);<br>rep.GetCaptionActor2D().SetCaption(text);<br>rep.GetCaptionActor2D().GetProperty().SetColor(0.0, 1.0, 0.0);<br>rep.SetAnchorPosition(pointer);<br>rep.GetCaptionActor2D().GetTextActor().SetPosition(textPos1[0], textPos1[1]);<br>rep.GetCaptionActor2D().GetTextActor().SetPosition2(textPos2[0], textPos2[1]);<br>captionWidget.SetRepresentation(rep);<br>m_renderWin.Render();<br><br>Thanks<br>Liu Peng<br></div>
