<div dir="ltr">In my case the image center is [218.0732421875, 218.0732421875, 158.75], which I got from ImageData.GetCenter()<br><br>So you mean to say, first I translate the image,do the rotation and translate back.<br><br>
Is that right?<br><br>Thanks<br><br>Jothy<br><br><div class="gmail_quote">On Mon, Mar 15, 2010 at 2:26 PM, Darshan Pai <span dir="ltr"><<a href="mailto:darshanpai@gmail.com">darshanpai@gmail.com</a>></span> wrote:<br>

But how to rotate around the Image centre. I get the Image centre from vtkImagedata.GetCenter() method. But when I view the image it seems to be shifted.Here is the code<br>
<br>xform=vtk.vtkTransform()<br>xform.PostMultiply()<br>#xform.RotateWXYZ(10,218.0732421875, 218.0732421875, 158.75)<br>x,y,z=Image.GetCenter<br>xform.RotateWXYZ(50,x,y,z)# rotate 50 degs <br>res=vtk.vtkImageReslice()<br>
res.SetInput(Image.GetOutput())<br>res.SetInformationInput(Image.GetOutput())<br>res.SetResliceTransform(xform)<br>res.SetInterpolationModeToLinear()<br>res.Update()<br><br>Whats wrong??<br><br>Thanks<br><br>Jothy<br></div>
