[IGSTK-Users] Problem while linking ObjectRepresentations withmouse events

[Vincent Gratsac]

//Hi all,

I tried to add a method to ImageObjectRepresentation class in order to 
be able to change its slice number by giving a physical point. This 
method is called /RequestResliceToPhysicalPoint(PointType point)./

Would you be interested in committing it into IGSTK ? Or do you think 
this is not a right way to do ?
