[vtkusers] CopyAndCastFrom()

[Talita Perciano]

Hi,

I want to get a slice (35 as in the example bellow) from a DICOM volume
using CopyAndCastFrom(). In this example the extent of the original volume
is (0,511,0,511,0,81). What am I doing wrong here?

image_slice->SetSpacing(reader->GetOutput()->GetSpacing());
image_slice->SetOrigin(reader->GetOutput()->GetOrigin());
image_slice->SetDimensions(512,512,1);
image_slice->SetScalarTypeToShort();
image_slice->SetNumberOfScalarComponents(reader->GetNumberOfComponents());
image_slice->SetWholeExtent(reader->GetOutput()->GetWholeExtent());
image_slice->AllocateScalars();
image_slice->CopyAndCastFrom(reader->GetOutput(), 0,511,0,511,35,35);


Thank you in advance,

Talita
