Methods

controlPoints

  • controlPoints(): Position[]

  • Get an array of control point model positions for a {@code curve-style: bezier) or {@code curve-style: unbundled-bezier} edge.

    While the control points may be specified relatively in the CSS, this function returns the absolute model positions of the control points. The points are specified in the order of source-to-target direction. This function works for bundled beziers, but it is not applicable to the middle, straight-line edge in the bundle.

    Returns Position[]

midpoint

  • midpoint(): Position

  • Get the model position of the midpoint of the edge.

    The midpoint is, by default, where the edge’s label is centred. It is also the position towards which mid arrows point. For curve-style: unbundled-bezier edges, the midpoint is the middle extremum if the number of control points is odd. For an even number of control points, the midpoint is where the two middle-most control points meet. This is the middle inflection point for bilaterally symmetric or skew symmetric edges, for example. For curve-style: segments edges, the midpoint is the middle segment point if the number of segment points is odd. For an even number of segment points, the overall midpoint is the midpoint of the middle-most line segment (i.e. the mean of the middle two segment points).

    Returns Position

segmentPoints

  • segmentPoints(): Position[]

  • Get an array of segment point model positions (i.e. bend points) for a {@code curve-style: segments} edge.

    While the segment points may be specified relatively in the stylesheet, this function returns the absolute model positions of the segment points. The points are specified in the order of source-to-target direction.

    Returns Position[]
