Package-Level Type Names (only one)

/* sort by: alphabet | popularity */

type NodeMarginCalculator (struct) NodeMarginCalculator is a direct port of ELK v0.8.1's calculator. Its switches intentionally mutate the receiver, mirroring the Java fluent API.

Package-Level Functions (total 4)

func CalculateLabelAndNodeSizes(model *graph.Model, parent graph.NodeID, filter func(graph.NodeID) bool) CalculateLabelAndNodeSizes processes every direct child of parent. This is the NodeDimensionCalculation entry point used by layered import.

func CalculateNodeMargins(model *graph.Model, parent graph.NodeID, excludeEdgeHeadTailLabels bool)

func NewNodeMarginCalculator() *NodeMarginCalculator

func ProcessNodeSize(model *graph.Model, parent, nodeID graph.NodeID, apply bool, _ bool) geometry.Point ProcessNodeSize applies ELK's fixed/minimum-size path and fixed-position port placement. Those are the paths exercised by D2's ELK graphs. The function deliberately exposes the same apply/ignore switches as the Java entry point so the remaining cell-system constraints can be added without changing callers.
