Type Alias DucPointBinding

Type declaration

• elementId: DucBindableElement["id"]

• fixedPoint: FixedPoint | null

  Represents a fixed point inside the bound element, defined as a normalized coordinate. This value is an array [x, y], where:

  • x (0.0 - 1.0) → The horizontal position inside the element (0 = left, 1 = right).

  • y (0.0 - 1.0) → The vertical position inside the element (0 = top, 1 = bottom). Unlike focus, fixedPoint ensures that the arrow stays pinned to a precise location inside the element, regardless of resizing or movement.

  • If fixedPoint is null, focus is used instead, meaning the arrow will attach dynamically to the edge.

  • If fixedPoint is set, it overrides focus, keeping the arrow attached to the exact specified point inside the element.

• focus: number

  Determines where along the edge of the bound element the arrow endpoint should attach. This value ranges from -1 to 1:

  • -1 → Attaches to the far left (for horizontal edges) or top (for vertical edges).
  • 0 → Attaches to the exact center of the edge.
  • 1 → Attaches to the far right (for horizontal edges) or bottom (for vertical edges).

  Focus ensures that the arrow dynamically adjusts as the bound element moves, resizes, or rotates.

• gap: PrecisionValue

  The gap distance between the bound element and the binding element.

• head: DucHead | null

  The head of the line Reference: https://www.figma.com/design/5rYcUlscflBabQ9di2iFJ5/duc-Architecture?node-id=313-43&t=gNEFgevk9KZ3oAun-1

• point: { index: number; offset: number } | null

  Represents a point within a DucLinearElement.

  The offset ranges from -1 to 1:

  • 0 corresponds to the actual point.
  • -1 and 1 represent the percentage of the distance between the point at index and the previous or next point in the points array, respectively.
