[Insight-developers] still some VectorImage problems

[Gaetan Lehmann]

Hi Karthik,

I thought everything was working with VectorImage, but I was wrong.
While trying to build java wrappers, I get the following error:

It seems that with java, the return type of an overloded method must be  
exactly the same than the one of the superclass, which is not the case  
here.
Do you know how to fix that problem ?
