[Insight-users] Are there readers capable of streaming?

[Luis Ibanez]

Hi Eugen,

The following ITK Readers are capable of Streaming:

          1) MetaImage
          2) Nifti

One way to know what readers can provide streaming
is to go to the Insight/Code/IO directory and to
grep for the files that implement the following
method:


   GenerateStreamableReadRegionFromRequestedRegion()



   Regards,


       Luis
