    • contains

      public boolean contains(int x, int y)
      Description copied from class: Roi
      Returns whether the center of pixel (x,y) is contained in the Roi. The position of a pixel center determines whether a pixel is selected. Points exactly at the left (right) border are considered outside (inside); points exactly on horizontal borders are considered outside (inside) at the border with the lower (higher) y. This convention is opposite to that of the java.awt.Shape class.
      Overrides:
      contains in class Line
