[vtkusers] screen shot get clippet

[Gilad Arnon]

Hi all,

I'm trying to get a png file out of my polydata.
(I take several pictures from different angles.)
but sometimes the outcome is clipped.

this is my code

vtkSmartPointer<vtkSTLReader> reader = vtkSmartPointer<vtkSTLReader>::New();

reader->SetFileName(name);

reader->Update();

inputPolyData = reader->GetOutput();

vtkSmartPointer<vtkPolyDataMapper> inputPolyMapper =
vtkSmartPointer<vtkPolyDataMapper>::New();

inputPolyMapper->SetInputData(inputPolyData);

vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();

actor->SetMapper(inputPolyMapper);

vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();

vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();

vtkSmartPointer<vtkRenderWindowInteractor> interactor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();

interactor->SetRenderWindow(renderWindow);

vtkSmartPointer<vtkAxesActor> axes =

vtkSmartPointer<vtkAxesActor>::New();

vtkSmartPointer<vtkOrientationMarkerWidget> axisWidget =
vtkSmartPointer<vtkOrientationMarkerWidget>::New();

axisWidget->SetOutlineColor(0.9300, 0.5700, 0.1300);

axisWidget->SetOrientationMarker(axes);

axisWidget->SetInteractor(interactor);

renderWindow->AddRenderer(renderer);

axisWidget->SetEnabled(1);

axisWidget->InteractiveOff();

renderWindow->SetOffScreenRendering(1);

renderer->AddActor(actor);

vtkSmartPointer<vtkLightKit> lightKit = vtkSmartPointer<vtkLightKit>::New();

lightKit->AddLightsToRenderer(renderer);

renderer->ResetCamera();

renderWindow->Render();

vtkSmartPointer<vtkWindowToImageFilter> windowToImageFilter =

vtkSmartPointer<vtkWindowToImageFilter>::New();

windowToImageFilter->SetInput(renderWindow);

windowToImageFilter->SetMagnification(3);

windowToImageFilter->SetInputBufferTypeToRGBA();

windowToImageFilter->Update();


for example I receive this picture for a rectangle:


[image: Inline image 1]


Can someone assist?


Thanks,

Gilad.
