Roughen a polyline (multiple connected segments)

Converts a multi-vertex polyline into n_passes roughened stroke paths. Each path is a matrix with columns x and y (inch coordinates). Uses a seeded local RNG so the user's .Random.seed is never mutated (T-CORE-06).

Usage

roughen_polyline(x, y, roughness = 1, bowing = 1, n_passes = 2L, seed = NULL)

Arguments

x, y

Numeric vectors of polyline vertices in inch space. Must have the same length ≥ 2.

roughness

Non-negative roughness radius (inches at scale). Default 1.

bowing

Non-negative bowing multiplier. Default 1.

n_passes

Positive integer number of stroke passes (default 2).

seed

Integer seed for reproducibility (ADR-0004).

Value

A list of n_passes matrices (columns x, y), one per pass.
