[Insight-users] Error using ShrinkImageFilter

[Miller, James V (Research)]

If the input images is changing size, then you need to call
UpdateLargestPossibleRegion() instead of calling Update().

The pipeline caches information about previous requests.  If the image
size changes, then the this error will occur whenever the new input image
cannot satisfy the size of the request from the previous update.

Subject: [Insight-users] Error using ShrinkImageFilter


Hi all,

I want to reduce the resolution of one image in real time aplication, for
that, 
I am using "ShrinkImageFilter", in the first execution there aren?t errors,
but 
after, I have: 

ExceptionObject caught !
D:\InsightToolkit-1.6.0\Code\Common\itkDataObject.cxx:376:
Requested region is (at least partially) outside the largest possible
region.

I am looking for this problem in the guide, but I dont understand the use
and 
how to use? of the "GenerateInputRequestedRegion()" 
and "GenerateOutputInformation()"
this error is for that? or not?
Could somebody help me?

Regards Dani,
Thanks.

Excuse my english...
