hypo_recolor_grob_table: Creates a table svg color variants

In k-hench/hypoimg: Provides Hypoplectrus image annotations

Creates a table svg color variants

Description

hypo_recolor_grob_table turns a svg obect into a table of color variants.

Usage

hypo_recolor_grob_table(
  svg,
  layer = 1,
  levels,
  colormap,
  x = rep(0.5, length(levels)),
  y = rep(0.5, length(levels)),
  angle = rep(0, length(levels)),
  width = 1,
  height = 1
)

Arguments

svg	svg object (manatory), the svg object
layer	integer skalar (manatory, default = 1), the layer to recolor
levels	vector (manatory), the levels of the intended facets
colormap	string vector (manatory), the new colors
x	numeric vector (optional), x-center of the annotation (length = length(leveles))
y	numeric vector (optional), y-center of the annotation (length = length(leveles))
angle	numeric scalar (optional), angle of the annotation
width	numeric scalar (optional), width of the annotation
height	numeric scalar (optional), height of the annotation

Details

This function creates a tibble of colorvariants from a 'raw' svg. This table can then be fed into geom_hypo_grob() to annotate factes of a ggplot with individual color variants of the svg image.

Examples

svg_file <- system.file("extdata", "logo.c.svg", package = "hypoimg")
svg <- hypo_read_svg(svg_file)
svg_tab <- hypo_recolor_grob_table(svg,LETTERS[1:3], c('red', 'green', 'blue'), layer = 1)
ggplot() +
 geom_hypo_grob(data = svg_tab,
  aes(x =x, y = y, grob = grob)) +
  facet_wrap(grp ~ .)
