[vtkusers] create a vtkImageData from scratch

[P B]

Hi everyone,
 
   I am trying to create a VTK imageData from scratch. I currently have a volume in an inhouse format. I have all the information to create a new volume (voxel intensities, dimensions, spacing, origin, model matrix) but do not know what to use to transform it to vtk. The volume went through a series of transformation and the model matrix is important. How can I create a vtk volume with the same orientation, intensities, etc..? I've searched in the archives of the vtk mailing list and found nothing that could help. If someone has an example that would be very helpfull,
 
Thanks in advance!
Pascale
