[vtkusers] paint an image area

[dirce]

Hi all

 I need help, i’m trying to paint an área in a imagedataset. I have a black
backround with some white points. 

I want to close the  area that is defined by the points, and then set all
the interior to white, so I can obtain an image to use later in a mask.

Thank´s all, any help will be much appreciated.
