  XImage_Support help page


  GENERAL DESCRIPTION

  The XImage_Support widget modifies the support of the input
  image by either applying a circular mask centered on the
  image maximum or extracting the principal connected component,
  i.e. the set of pixels above a pre-fixed intensity threshold
  and connected by a path to the maximum intensity pixel.
