[vtkusers] vtkImageData with different spacing

[Vincent LEFORT]

It's not possible to have vtkImageData with different spacing.

You can use the vtkRectilinearGrid to do same thing, but vtkImageAlgorithm will not work on it. After you can maybe convert this rectilinear grid to an vtkImageData ...

Hi Darshan,

Thanks! Reading the class documentation says: "vtkImageChangeInformation<http://www.vtk.org/doc/nightly/html/classvtkImageChangeInformation.html> modify the spacing, origin, or extent of the data without changing the data itself. The data is not resampled by this filter, only the information accompanying the data is modified."

Is it possible a vtkImageData have varied spacing?

Regards,
Paulo Amorim

I think you need to use the vtkImageChangeInformation to do this.

Hi all!

I need generate a vtkImageData from two vtkImageData with different pixel spacing in the z axis. Is there any alternative to do this in the VTK?

Regards,
Paulo
