<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi all,
<br>
<br>
<span>Code like </span><br>
<br>
<span>void DlgResVis2D::saveTmpPicture(QString &filename) </span><br>
<span>{ </span><br>
<span> vtkNew<vtkWindowToImageFilter> windowToImageFilter; </span><br>
<span> vtkWindow* pRenderWindow = (vtkWindow *) m_pView->GetRenderWindow();
</span><br>
<br>
<span> windowToImageFilter->SetInput(pRenderWindow); </span><br>
<span> windowToImageFilter->SetMagnification(1); </span><br>
<span> windowToImageFilter->SetInputBufferTypeToRGBA(); </span><br>
<span> windowToImageFilter->Update(); </span><br>
<br>
<span> vtkSmartPointer <vtkPNGWriter> writer = vtkSmartPointer <vtkPNGWriter>::New();
</span><br>
<span> writer->SetFileName(filename.<span class="bold highlight search-highlight">toAscii</span>());
</span><br>
<span> writer->SetInputConnection(windowToImageFilter->GetOutputPort()); </span>
<br>
<span> writer->Write(); </span><br>
<span>} </span><br>
<br>
<span><span class="bold highlight search-highlight">exports</span> a picture in <span class="bold highlight search-highlight">
PNG</span> on 5 computers. On the sixth computer produce only a 2KB empty <span class="bold highlight search-highlight">
PNG</span> file (no error is prompted), while on each other 5 computers produce 35KB
<span class="bold highlight search-highlight">PNG</span> file with the same <span class="bold highlight search-highlight">
image</span>. </span><br>
<span>Does anybody encounter the same behavior? </span><br>
<br>
<span>Thx in advance, </span><br>
