Create a sketchy polygon grob with optional hachure fill

Usage

sketch_polygon_grob(
  x,
  y,
  id = NULL,
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  fill_gp = gpar(),
  outline_gp = gpar(),
  fill_style = "hachure",
  hachure_angle = 45,
  hachure_gap = NULL,
  fill_weight = 0.5,
  fill_roughness = NULL,
  fill_seed = NULL,
  name = NULL,
  vp = NULL
)

Arguments

x, y

Numeric npc [0,1] coordinates.

id

Group IDs (same semantics as grid::polygonGrob).

roughness, bowing, n_passes, seed

Sketch parameters for the outline.

fill_gp

gpar() for fill lines (col sets fill-line colour).

outline_gp

gpar() for the rough outline stroke.

fill_style, hachure_angle, hachure_gap, fill_weight

Fill parameters (hachure_gap in device inches; NULL picks 15% of the shape's smaller drawn extent, clamped to [0.04, 0.4] inches).

fill_roughness

Roughness of the fill strokes. NULL (default) ties it to the outline as roughness * 0.5; set a number to control the fill texture independently of the outline.

fill_seed

Seed for the fill strokes. NULL (default) derives it from seed; set an integer to vary the fill pattern without moving the outline.

name, vp

Passed to grid::grob().

Value

A SketchPolygonGrob grob subclass.
