Create a sketchy ellipse / circle grob

Source: R/grob-sketch.R
sketch_ellipse_grob.Rd

Draws one or more roughened ellipses whose centres are in npc [0,1] and whose radii are npc fractions of the viewport (converted to device inches in makeContent(), so a "circle" in data units may appear elliptical on a non-square panel — matching ggplot2's coordinate semantics).

Usage

sketch_ellipse_grob(
  x,
  y,
  rx,
  ry,
  roughness = 1,
  n_passes = 2L,
  seed = NULL,
  fill_style = NULL,
  hachure_angle = 45,
  hachure_gap = 0.07,
  fill_weight = 0.5,
  fill_gp = gpar(),
  outline_gp = gpar(),
  name = NULL,
  vp = NULL
)

Arguments

x, y

Numeric npc centre coordinates (vectors).

rx, ry

Numeric npc radii (vectors, recycled to x).

roughness, n_passes, seed

Sketch parameters.

fill_style, hachure_angle, hachure_gap, fill_weight

Fill parameters; set fill_style = NULL or "solid" for outline only.

fill_gp

gpar() for the fill lines.

outline_gp

gpar() for the rough outline stroke.

name, vp

Passed to grid::gTree().

Value

A SketchEllipseGrob grob subclass.
