<span>Hello!</span><div><br></div><div>I have been trying to figure out if it is possible to rotate data directly from a imagedata xml file. Can anyone lend me a hand on how to do that?</div><div><br>
</div><div>I am currently exporting data from matlab to a .vti imagedata xml file and importing it to paraview (that is I am writing the file without using vtk classes) but I</div><div>do not know how to rotate the data. According to the <a href="http://www.vtk.org/VTK/img/file-formats.pdf" style="color:rgb(17,85,204)" target="_blank">www.vtk.org/VTK/img/file-formats.pdf</a> file there is a Coordinate tag</div>
<div>but it does not appear to have an effect when importing, but on the other hand its barely documented and I am really just guessing on how to use it.</div><div><br></div><div>Currently I am testing with this data (but my actual data is much larger):</div>
