[Insight-users] Stitching the image region back after RegionOfInterestImageFilter

[Karthik Krishnan]

Hi Quan,

One way is of achieving arbitrary padding use the ResampleImageFilter. 
See any of the examples in Examples/Filtering/Resample*.cxx. You can set 
your output size, start index, output origin, and background pixel value 
etc..

Thanks
regards
karthik
