[Insight-developers] Reorganized IO directory

[Lydia Ng]

Hi,

One of my existing Examples was using itkRawImageWriter
which has now been removed in the IO directory reorg.

I was going to switch over to using=20
itkRawImageIO/itkImageFileWriter but I have been unsuccessful.

The first problem is that I can't instantiate a itkRawImageIO
object because abstract function ImageIO::ReadImageInformation
have not been implemented in itkRawImageIO.

The second problem is that ImageFileWriter::Write()
doesn't do anything.
And the doing bit of ImageFileWriter::Write( ioRegion )
has been hashed defined out.

Could we possibly have RawImageWriter back in the
interim?=20
I would like to see my MultiResMIRegistration Example
work for the alpha and also it's nice to be
able to dump out raw images when I am debugging my
algorithms.

-Lydia
