<p>Hi,<br>

<br>

I use the following lines of code to save the screen to a .png file.<br>

<br>

</p>

<div>    // set up screenshot  <br>

    vtkSmartPointer<vtkWindowToImageFilter> windowToImageFilter =<br>

    vtkSmartPointer<vtkWindowToImageFilter>::New();<br>

    windowToImageFilter->SetInput(renderer->GetRenderWindow());<br>

    //set the resolution of the output image <br>

    windowToImageFilter->SetMagnification(Quality);<br>

    //also record the alpha (transparency) channel<br>

    windowToImageFilter->SetInputBufferTypeToRGBA();<br>

    // read from the back buffer<br>

    windowToImageFilter->ReadFrontBufferOff();<br>

    windowToImageFilter->Update();<br>

    // write image<br>

    vtkSmartPointer<vtkPNGWriter> writer =<br>

    vtkSmartPointer<vtkPNGWriter>::New();<br>

    QString full_path = Path + "/Screenshot_" + QTime::currentTime().toString().remove(":") + ".png";<br>

    writer->SetFileName(full_path.toStdString().c_str());<br>

    writer->SetInputConnection(windowToImageFilter->GetOutputPort());<br>

    writer->Write();</div>

<br>

Everything works great but the <span>vtkBillboardTextActor3D</span> actors are not part of the resulting image.<br>

(Of course I added them to the renderer and I can see the text on the screen!)<br>

<br>

What could be the problem?<br>

<br>

Thank you!<br>

<br>
