Steps To Reproduce

#include <vtkActor.h>
#include <vtkProperty.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>

        vtkSphereSource *sphere = vtkSphereSource::New();
        sphere->SetCenter(1.333, 0, 0);
        sphere->SetRadius(0.5);

        vtkPolyDataMapper *mapper = vtkPolyDataMapper::New();
        mapper->SetInput(sphere->GetOutput());

        vtkActor *actor= vtkActor::New();
        actor->SetMapper(mapper);
        actor->GetProperty()->SetColor(0, 1, 0);

        vtkRenderer *ren = vtkRenderer::New();
        ren->AddActor(actor);

        vtkRenderWindow *renWin = vtkRenderWindow::New();
        renWin->AddRenderer(ren);
        renWin->SetOffScreenRendering(1);
        renWin->Render();

        vtkWindowToImageFilter *win2img = vtkWindowToImageFilter::New();
        win2img->SetInput(renWin);

        vtkPNGWriter *writer = vtkPNGWriter::New();
        writer->SetInput(win2img->GetOutput());
        writer->SetFileName("sphere.png");
        writer->Write();
