<br><div dir="ltr">My mistake -- the method is vtkCaptionActor2D::GetCaptionTextProperty. It also looks like the caption text actor is initialized to TEXT_SCALE_TO_PROP (see vtkTextActor's TextScaleMode documentation). This will always resize the text to fit inside a specified bounding box, instead of using the font size. Try:<div><br></div><div>captionActor->GetTextActor()->SetTextScaleModeToNone();</div><div>captionActor->GetCaptionTextProperty()->SetFontSize(fontSize);</div><div><br></div><div>HTH,</div><div>Dave</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 20, 2016 at 10:15 AM, Liu_tj <span dir="ltr"><<a href="mailto:tjlp@netease.com" target="_blank">tjlp@netease.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; padding-left: 1ex; border-left-color: rgb(204, 204, 204); border-left-width: 1px; border-left-style: solid;"><div>Hi, David,</div><div><br></div><div>There is no member method GetTextProperty() for vtkCaptionActor2D.
