[vtkusers] converting java array to vtkimage data

[nikhil singhania]

Sir,
Thank you for your reply.The code is working for all other vtk
functions just giving error for  vtkimagedata .Does vtkimagedata
require any additional file to be loaded. Environmental variable  path
is also set.
Thank You.

Best regards,
Nikhil
