Hi there,<br><br>I am confusing about using GetLargestPossibleRegion() and GetRequestedRegion(). What are the differences?<br><br>GetLargestPossibleRegion() is getting all the pixels in the image.<br><br>And GetRequestedRegion() is getting all the none-zero pixels. Is that right?<br>
<br><br>Cheers,<br>Aaron <br>
