[vtkusers] How can I extract an image plane from image reslice object?

[jose manjon]

Hi there,

How can I extract an image plane from image reslice object?

I use this:

reslice=vtkImageReslice::New();
reslice->SetInput(data);
reslice->SetResliceTransform(transform);
reslice->InterpolateOn();
reslice->SetOutputSpacing(pDoc->resx,pDoc->resy,pDoc->resz);
reslice->SetBackgroundLevel(0);
reslice->GetInput()->SetUpdateExtentToWholeExtent(); // to speed up
reslice->GetInput()->Update();

now I want to get an arbitrary image plane on a  vtkImageData object:

 vtkImageData * ima=reslice->GetOutput();

but it is very slow!!!!

there is any other way to access image data without using image viewer output?

I need the images to show them on a MFC CView derived class...

thanks in advance

jose
