[Insight-users] Running filter on images with different LargestPossibleRegion sizes

[Mackie, Prescott M]

Dr. Mailinglist,

I created a filter in which I am forming an output image based on information from four input images.
However, the fourth input image has a larger region size from the other three (first three have same size).
I am getting an error that reads:

terminate called after throwing an instance of 'itk::InvalidRequestedRegionError'
what(): ......./Insight/Code/Common/itkDataObject.cxx:397:
Requested region is (at least partially) outside the largest possible region.


I think my problem lies in the ThreadedGenerateData() function of the .txx code.  Is there someway to run the
'while' loop for only a Region Size of the smaller image?

The .txx and .h files are attached.  Ignore most of the comments in the code. I templated each code off
of the checkerboard image filters in the library.
Let me know if I need to explain some functions or my problem a little bit more clearly.
Thanks.

Scott
