[Insight-users] Buffered Regions

[Vikash Gupta]

Hello Everyone, 
I am trying to iterate over a smaller region of an image, and Probably I am doing something wrong which I do not understand. 
So, here is what i am doing 


1. define the size of the region. 
2. define the index at which the region should start 
3. define the region using the above two values 


Now when I define the iterator, How should I feed the region, should it be the function GetRequestedRegion() or GetBufferedRegion() 


FineScalarIteratorType itScalartemp ( tempScalar , tempScalar -> GetBufferedRegion ()); 
In the above line, tempScalar is the image object over which I am trying to iterate. 
Please suggest Thanks Vikash
