[Insight-users] Big endian/little endian

[Radhika Sivaramakrishna]

Hi Luis,
I did try this but it is still writing this out as little endian. Is there a
way to force it to write in big endian format or force byte swapping?
Thanks
Radhika

Hi Radhika,

Yes, you can specify the desired Endian-ness
when writing the image.

You simple need to create the ImageIO object
on your own (not let the ImageIO factory do it
for you) and invoke on it any of the following
methods:


       SetByteOrder (ByteOrder _arg)
       SetByteOrderToBigEndian ()
       SetByteOrderToLittleEndian ()


These methods are defined in ImageIOBase
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ImageIOBase.html


The code will look like

typedef itk::MetaImageIO   ImageIOType;

ImageIOType::Pointer metaIO = ImageIOType::New();

  metaIO->SetByteOrderToBigEndian();

  // XOR

  metaIO->SetByteOrderToLittleEndian();


typedef itk::ImageFileWriter< ImageType > WriterType;


WriterType::Pointer writer = WriterType::New();

writer->SetImageIO( imageIO );
writer->SetFileName("myfilename.mhd");

writer->SetInput( filter->GetOutput() );

writer->Update();




Regards,


    Luis
