[Insight-users] Drawing a circle

[Julien Jomier]

Hi Ilaria,

You can also use a combination of itkEllipseSpatialObject and 
SpatialObjectToImageFilter.

Just create a circle with the itkEllipseSpatialObject<2> by specifying a
radius. Then pass the ellipse to the SpatialObjectToImageFilter to get a 
binary image.

Hope that helps,

Julien
