<div dir="ltr">Thanks all for getting back to me. I put in a call to update the importFilter and upon debugging found that the image variable is getting the correct size settings and number of elements (or at least it is the same as the importFilter finds). I tried casting the imageSize to unsigned int and got the same numbers throughout, and still had the exception at castImage->Update().
