[JAVA2D] Shape question

[Ted Hill]

Hello,   If I have a closed Polygon or GeneralPath, is there some way to 'grow' it or 'shrink' it?   For example, if my GeneralPath were circular, is there some way to get both a big circle and little circle from it, where they all share the same center point?   What if the Polygon or GeneralPath have an 'irregular' shape, how would I grow and shrink them?   Thank you,   Ted Hill
