Field Detail

• state

  protected net.imglib2.algorithm.region.localneighborhood.EllipseCursor.CursorState state

  The state of the cursor.

• nextState

  protected net.imglib2.algorithm.region.localneighborhood.EllipseCursor.CursorState nextState

  The state of the cursor.

• rx

  protected int rx

  When drawing a line, the line length.

• rxs

  protected int[] rxs

  Store X line bounds for all Y

• position

  protected long[] position

  Store current relative position with respect to the ellipse center.

• allDone

  protected boolean allDone

• hasNext

  protected boolean hasNext

Constructor Detail

• EllipseCursor

  public EllipseCursor(AbstractNeighborhood<T> ellipse)

  Construct a EllipseCursor on an image

  Parameters:

  ellipse - the neighborhood of this cursor

Method Detail

• getDistanceSquared

  public double getDistanceSquared()

• getPhi

  public double getPhi()

  Return the azimuth of the spherical coordinates of this cursor, with respect to its center. Will be in the range ]-π, π].

  In spherical coordinates, the azimuth is the angle measured in the plane XY between the X axis and the line OH where O is the sphere center and H is the orthogonal projection of the point M on the XY plane.

• reset

  public void reset()

• fwd

  public void fwd()

• hasNext

  public boolean hasNext()

• copyCursor

  public Cursor<T> copyCursor()

• copy

  public Sampler<T> copy()

  Returns:

  - A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)
