canvas_strokes: Draw Strokes

In aRtsy: Generative Art with 'ggplot2'

Draw Strokes

Description

This function creates an artwork that resembles paints strokes. The algorithm is based on the simple idea that each next point on the grid has a chance to take over the color of an adjacent colored point but also has a change of generating a new color.

Usage

canvas_strokes(
  colors,
  neighbors = 1,
  p = 0.01,
  iterations = 1,
  resolution = 500,
  side = FALSE
)

Arguments

colors	a string or character vector specifying the color(s) used for the artwork.
neighbors	a positive integer specifying the number of neighbors a block considers when taking over a color. More neighbors fades the artwork.
p	a value specifying the probability of selecting a new color at each block. A higher probability adds more noise to the artwork.
iterations	a positive integer specifying the number of iterations of the algorithm. More iterations generally apply more fade to the artwork.
resolution	resolution of the artwork in pixels per row/column. Increasing the resolution increases the quality of the artwork but also increases the computation time exponentially.
side	logical. Whether to put the artwork on its side.

Value

A ggplot object containing the artwork.
