Sketchy legend keys

draw_key_* functions used by the sketch geoms so their legends render with the same hand-drawn character. Not called directly; passed as the draw_key field of a geom (see ggplot2::draw_key).

Usage

draw_key_sketch_path(data, params, size)

draw_key_sketch_point(data, params, size)

draw_key_sketch_polygon(data, params, size)

Arguments

data

A single-row data frame of the key's aesthetics.

params

The layer's parameter list (roughness, seed, fill_style, ...).

size

Key size in mm (unused; kept for the draw_key contract).

Value

A grid grob.
