[Insight-developers] Re: ImageIO Streaming

[Luis Ibanez]

Hi Doug,

Yes, the largest possible region is defined in ReadImageInformation().

So its value is available by the time the ImageFileReader calls
CanStreamRead() and DetermingStreamableRegionFromRequestedRegion().

I'll remove CanStreamRead() from the API in the Sandbox.


   Thanks


      Luis
