Hi,<div><br></div><div>Can we iterate safely using this raw buffer pointer?</div><div><br></div><div>Maybe there is some padding to ensure some byte alignment property?</div><div><br></div><div>Also if there is a GetBufferPointer notice that there is no SetBufferPointer. So I don't think you can just set some buffer pointer as is the case with some C++ STL containers. With that API, you will at least need to make a copy of the contents, and even then we must make sure that there is enough allocated memory.</div>
<div><br></div><div>After all, what would be the usefulness of the "ImportImageFilter" if we could simply and safely set a raw buffer pointer?</div><div><br></div><div>And finally what precisely the "ImportImageFilter" does under the hood? Apprently it does _NOT_ make a copy of your buffer pointer. So maybe that is fast. But I am not sure of what I am saying.</div>

The common approach is to use the iterator of the ITK image and assign the c++ array.<br>
Any other fast way?<br>Best<br>df<br><br>
