[vtkusers] vtkImageViewer and vtkLine

[Stefano Sclaverano]

Hi all,

Finally I drew the line in this way, but it's not very correct :

. . .

// The line definition
seeds = vtkLineSource::New();
seeds->SetPoint1(0.0,0.0,0.0);
seeds->SetPoint2(0.0,0.1,0.0);
seeds->SetResolution(20);

// The Line Mapper
seedsMapper = vtkPolyDataMapper::New();
seedsMapper->SetInputConnection(seeds->GetOutputPort());

// The line Actor
seedsActor = vtkActor::New();
seedsActor->SetMapper(seedsMapper);
seedsActor->GetProperty()->SetColor(1.0,1.0,1.0);
seedsActor->GetProperty()->SetRepresentationToPoints();
seedsActor->GetProperty()->SetOpacity(0.95);

// The line Render
seedsRen = vtkRenderer::New();
seedsRen->AddActor(seedsActor);
seedsRen->SetViewport(0.499,0.0,0.501,1.0);

// The ImageViewer Render
ren = vtkRenderer::New();

// The general RenderWindow
renWindow = vtkRenderWindow::New();
renWindow->AddRenderer(ren);
renWindow->AddRenderer(seedsRen);

// The Actor2D of ImageViewer
ren->AddActor2D(viewer->GetActor2D());

// Render the entire world
this->GetInteractor()->Render();

. . .

All better ideas are welcome!
Thanks
