Hi, i'm trying to saving a DICOM file into another DICOM file with some transformation like IntensityWindowingImageFilterType adapted from the <a href="http://www.itk.org/Wiki/ITK/Examples/DICOM/ResampleDICOM">http://www.itk.org/Wiki/ITK/Examples/DICOM/ResampleDICOM</a> example. The only problem that occurs it the "brightness" doesn't change on the new DICOM file created during the process but the "contrast" changes is ok. This snippet of code corresponds the moment that occurs the passage of parameters to the transformation of the IntensityWindowingImageFilterType and the moment that is written a new DICOM file.<br clear="all">
