[vtkusers] converting java array to vtkimage data

[Sebastien Jourdain]

Hi Nikhil,

"Exception in thread "main"
java.lang.UnsatisfiedLinkError:vtk.vtkImageData.VTKInit()J

Means their is an issue with the link to the native layer.

So make sure those library have well been loaded before. Because depending
on your code and system,
those library might not be loaded when you use vtkImageData and might be
loaded when used with other VTK functions. Try to write  "new vtkPanel();"
prior the "vtkImageData image = new vtkImageData();".
(vtkPanel embed this native library loading lines...)

Seb
