[vtkusers] about minimizing memory usage

[Lic. José M. Rodriguez Bacallao]

hi folks, I am writing a simple dicom viewer with vtk and gdcm. I am
using vtkGDCMImageReader to load my files in conjunction with
IPPSorter. For minimizing memory usage I need to have in memory just
three images from for example, 200, when the user need to see the
slice 3 + 1, then load the next slice and unload the old first loaded
slice from the old 3 slices and so on. Is something like a dynamically
moving update extent. How do I achieve that in vtk?.
