[Insight-users] Restrict filter execution to certain region

[Karthik Krishnan]

Hi Jens,

It is possible.

If you have a chain of filters or let's say a filter2 which takes input from filter2 and you only want to process a region region2 from the output that filter1 generates,

//
//Define region2....which is a subset of filter1->GetLargestPossibleRegion
//

filter2->SetInput(filter1->GetOutput());
filter2->GetOutput()->SetRequestedRegion(region2);

Please also take a look at "How to write a filter" chapter of the SW Guide.

Thanks
regards
karthik
