<p>Hi guys,</p>
<p><br>
</p>
<p>I want to save screenshot as png image following the example. Unfortunately, the code went into
<span style="font-family:Calibri,Arial,Helvetica,sans-serif,'Apple Color Emoji','Segoe UI Emoji',NotoColorEmoji,'Segoe UI Symbol','Android Emoji',EmojiSymbols; font-size:16px">
windowToImageFilter->Update()</span> method and never came back. Below is the snippet:</p>
<p><br>
</p>
<p></p>
<div>// Screenshot </div>
<div> vtkSmartPointer<vtkWindowToImageFilter> windowToImageFilter =</div>
<div> vtkSmartPointer<vtkWindowToImageFilter>::New();</div>
<div> windowToImageFilter->SetInput(renderWindow);</div>
<div> //windowToImageFilter->SetMagnification(3); //set the resolution of the output image (3 times the current resolution of vtk render window)</div>
<div> //windowToImageFilter->SetInputBufferTypeToRGBA(); //also record the alpha (transparency) channel</div>
<div> //windowToImageFilter->ReadFrontBufferOff(); // read from the back buffer</div>
<div> windowToImageFilter->Update();</div>
<div><br>
</div>
<div> vtkSmartPointer<vtkPNGWriter> writer =</div>
<div> vtkSmartPointer<vtkPNGWriter>::New();</div>
<div> writer->SetFileName("e:/screenshot2.png");</div>
<div> writer->SetInputConnection(windowToImageFilter->GetOutputPort());</div>
<div> writer->Write();</div>
<div><br>
</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>renderWindow->Render();</div>
<div> timerLog->MarkEvent("finish rendering");</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>renderWindowInteractor->Start();</div>
<br>
<p></p>
<p>I am using win10, vtk6.3 on vc2013. </p>
<p><br>
</p>
<p>Any tips would be appreciated.</p>
<p><br>

<p>Cheers,</p>
