[Insight-users] Reading DICOM series: ByteSwapping

[Luis Ibanez]

Hi Jolinda,

Thanks for making your MRIConverter program available.
It is working great !.

About the addition of byte swapping for supporting
multiple platforms; there is helper class in ITK that
you may want to use for performing this task.

It is in the directory:   "Insight/Code/Common"

         itkByteSwapper.h
         itkByteSwapper.txx

http://www.itk.org/Insight/Doxygen/html/classitk_1_1ByteSwapper.html

This is not rocket science, but it is certainly painful
code that you may not want to write and debug if you don't
have to.

The itk::ByteSwapper is currently used by all the ITK ImageIO
objects, so it is fairly well tested in the range of platforms
that you can see in the Dashboard.

In case MRIConverter is not using ITK internally, you
may simply copy-paste code from this class into your
application. The class is now deriving from itk::Object,
but there is not fundamental reason why it should do so.

You couuld remove the code related to smart pointers
and then eliminate the itk::Object as base class.

---

You may find interesting also to look at the implementation
of the DICOM parser in ITK (as far as the byte swapping goes).
It is located in Insight/Utilities/DICOMParser.


Regards,



   Luis
