[vtkusers] Zooming Image

[ajay.arya at wipro.com]

Hi All,       
   
                Please let me know how to zoom the Image without using
vtkRenderWindowInteractor.
                I tried one code this is not working .This is the code
in which i am reading a BMP image.

                char* fname = "D:\\study1\\study.image1.bmp";       
                vtkBMPReader* reader=vtkBMPReader::New();
                reader->SetFileName(fname);

                 vtkImageData *data=vtkImageData::New();
                data = reader->GetOutput();
               
                vtkImageActor *actor=vtkImageActor::New();
                actor->SetInput(reader->GetOutput());

                vtkCamera *cam=vtkCamera::New();
                cam->Zoom(0.0);

              
                vtkRenderer *renderer=vtkRenderer::New();
                renderer->AddActor(actor);
                renderer->SetBackground(0.1,0.2,0.4);


                vtkRenderWindow *renwin=vtkRenderWindow::New();
                renwin->AddRenderer(renderer);
                renwin->SetSize(300,300);

                               
                 and vtkImage Magnify also i tried like that

                vtkImageMagnify *mag=vtkImageMagnify::New();
                mag->SetMagnificationFactors(a);

Thanks in advance
Ajay.
