ggplot_to_magiceye: Convert a ggplot2 object to a 3D autostereogram

In ryantimpe/MagicEye: Generate autostereogram 3D images

Description

Convert a 2ggplot2 object to a 3D autostereogram. Set dot colors used in final image.

Usage

ggplot_to_magiceye(
  ggobj,
  colors = c("#00436b", "#ffed89"),
  height = 6,
  width = 6
)

Arguments

ggobj	A ggplot object.
colors	Array of at least 2 color hex codes. Colors should be visually distinct and avoid using too many.
height	Height of output matrix. Larger values take longer to render, but will have more detail.
width	Width of output matrix. Larger values take longer to render, but will have more detail.

Value

A raster matrix for plot().

Examples

df <- data.frame(
group = c("Dog", "Cat", "Mouse"),
value = c(25, 30, 50)
)

library(ggplot2)
ggplot(df, aes(x="", y=value, fill=group))+
  geom_bar(width = 1, stat = "identity") +
  coord_polar(theta="y") -> pp

pp %>% ggplot_to_magiceye() %>% plot()
