[Insight-users] Streamable image reading?

[Luis Ibanez]

Hi Luke,


0) The ImageIO classes that support streaming should provide the
    method


        GenerateStreamableReadRegionFromRequestedRegion()


1) At this point the ImageIO class that best supports Streaming are
    MetaImageIO and Nifti.

2) I think (subject to verification) that Nifti is providing support
    for Streaming when reading, but not when writing.




An example on how to implement Streaming (reading) ImageIO classes
is available at:

    http://svn.na-mic.org/NAMICSandBox/trunk/ImageIOStreaming/

In particular, look at the directory

http://svn.na-mic.org/NAMICSandBox/trunk/ImageIOStreaming/Source/


and the YAFF format (YAFF stands for "Yet Another File Format"),
which is a toy (but functional) example of streaming.


Details are available in the technical report that you find at:
http://svn.na-mic.org/NAMICSandBox/trunk/ImageIOStreaming/Documents/TechnicalReport/




   Regards,


      Luis
