Get Label Position on Edge

Description

Calculates the position for an edge label (matches qgraph-style curves). For curved edges, the label is offset perpendicular to the edge to avoid overlapping with the edge line.

Usage

get_edge_label_position(
  x1,
  y1,
  x2,
  y2,
  position = 0.5,
  curve = 0,
  curvePivot = 0.5,
  label_offset = 0
)

Arguments

x1, y1	Start point.
x2, y2	End point.
position	Position along edge (0-1).
curve	Curvature amount.
curvePivot	Curve pivot position.
label_offset	Additional perpendicular offset for the label (in user coords). Positive values offset in the same direction as the curve bulge. Default 0 keeps the label on the computed edge position.

Value

List with x, y coordinates.
