[Paraview] Transforming an image

[Aviv Hurvitz]

Hi all,

I'm trying to use Paraview to visually verify the registration between
two 3D images. I calculated the registration with an external
application and have obtained a 3x3 matrix that I'd like to apply to the
moving image within Paraview. I've managed to read the images into
Paraview (they're in MetaImage format), but unfortunately I can't apply
a Transform filter on the moving image's object (of class
vtkMetaImageReader). The filter is grayed out.

Is there some way I'm missing to apply a spatial transformation to the
image? I'm willing to enter the tranformation manually through the user
interface or, better yet, to enter it directly into the session file
(*.pvs). I will break the transformation matrix into a translation *
rotation * scaling if need be.

By the way, I noticed the MetaImage header has  a TransformMatrix field
but it doesn't seem to have any effect in Paraview.

Thanks,

- Aviv
