Function: calculatePathLength()

calculatePathLength(path, steps?): number

Defined in: attributes/shape/path/length.ts:21

Estimates the total length of an SVG path by walking its commands and summing each segment's length. Straight segments (L/H/V/Z) are measured exactly; curves (C/S/Q/T) are flattened into steps line segments and summed.

Arcs (A/a) are approximated as a straight chord — see the note in the A/a case. For exact arc lengths, convert arcs to cubic Béziers before calling this.

Parameters

path

PathCommand[]

Path commands to measure (absolute or relative).

steps?

number = 20

Flattening resolution for curved segments. Higher is more accurate.

Returns

number
