[vtkusers] Rotating ImageData from vti file

[Christoffer Green]

Hello!

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?

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
do not know how to rotate the data. According to the
www.vtk.org/VTK/img/file-formats.pdf file there is a Coordinate tag
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.

Currently I am testing with this data (but my actual data is much larger):

<?xml version="1.0"?>
<VTKFile type="ImageData" version="0.1" byte_order="LittleEndian">
<ImageData WholeExtent="0 1 0 1 0 0" Origin="0.0 0.0 0.0" Spacing="0.4 0.4
0.4">
<Piece Extent="0 1 0 1 0 0">
<Coordinates>
<DataArray type="Float32" Name="x_coordinate" format="ascii">0.0 0.3
0.0</DataArray>
<DataArray type="Float32" Name="y_coordinate" format="ascii">0.5 0.2
0.0</DataArray>
<DataArray type="Float32" Name="z_coordinate" format="ascii">1.0 0.0
0.0</DataArray>
</Coordinates>
<PointData>
<DataArray type="Float32" Name="MagnitudeArray" format="ascii">0.1  0.3
 0.5  0.8</DataArray>
</PointData>
</Piece>
</ImageData>
</VTKFile>

Thanks
