[vtkusers] vtkVolume16Reader, How to read raw files f rom 002.dcm.raw to 123.dcm.raw?

[Peter Spring]

tcl code is below

vtkVolume16Reader reader
reader SetDataByteOrderToLittleEndian;
reader SetFilePrefix "d:\\rawdata\\"
reader SetFilePattern "%s%d.dcm.raw"
reader SetImageRange 2 123
[reader GetOutput] ReleaseDataFlagOn
reader SetDataSpacing ChangeToUrOwnValue
reader SetDataDimensions ChangeToUrOwnValue
reader Update
