[Insight-users] Streaming and ImageIO

[Jordi Inglada]

Hi all,

I am interested in reading very large images (i.e. 24000 x 24000 pixels) 
in an optimized way. I have read in section 13.3 of the Software Guide 
that streaming is implemented in the pipeline. My question is:

Do the ImageIO or the ImageFileReader classes use the streaming for file 
access? Or are the images completely loaded into memory and streaming is 
only used in ProcessObjects?

In the case where the latter is true, which would be the best way to 
implement streaming for the file access (we have our own ImageIO classes 
for our exotic image formats)?

Thanks for your help.

Jordi
