[Insight-users] physical coordinates vs image coordinates

[smythek at u.washington.edu]

Hi ITK,

I was wondering if anyone knows of a way I can "snap" physical coordinates (double) to image coordinates (int).  This is why:  I have registered two rather large images and would like to output the composite image.  PasteImageFilter cuts off the double index values since it takes only integer values, and I cannot use an iterator since I can't tell the iterator where to start in the composite image.
