[Insight-users] image casting

[Luis Ibanez]

Hi Zein,

You have several options depending on the pixel
types you are converting.

1) use the itkCastImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1CastImageFilter.html

This will apply only C-style casting.
so trunction and information loss is at
your own risk.

If you are casting from float to char,
for example you better use one of the
following:

2) itkRescaleIntensityImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1RescaleIntensityImage=
Filter.html

3) itkShiftScaleImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ShiftScaleImageFilter=
=2Ehtml

These two filters apply a linear transformation to
the intensities of the images.

Examples for all the three filters can be found in

     Insight/Examples/Filtering

in the file:

      CastingImageFilters.cxx


Please let us know if you have further questions

Thanks

Luis
