<div class="gmail_extra">Hi Sheena,</div><div class="gmail_extra"><br></div><div class="gmail_extra">I think if I get your question right, you'd probably have to use vtkImageReslice (<a href="http://www.vtk.org/doc/nightly/html/classvtkImageReslice.html">http://www.vtk.org/doc/nightly/html/classvtkImageReslice.html</a>). You can set the reslice axes from a matrix, and set the output origin, extent and spacing. It's a bit of a Swiss-army chainsaw, but it gets the job done.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">Setting the transform on the volume, for example (as Dženan says) would work for cases where you're translating, scaling or rotating. If you're shearing, for example, it probably won't work. And this will not affect the image; it'll only change the visualization. So if you want to use the transformed data for something else, you'll need to use reslice.</div>

Thanks for your reply. It is a 3D image. Well Strictly speaking I am not<br>
going to transform the image. I want to make the image distorted.<br>
<br>
Thank you,<br>
