Details

This function reads the logo path from the stored brand configuration and creates a ggplot2 annotation layer. The brand configuration must be loaded first using brand_set_ggplot().

The function supports PNG images and requires the 'png' and 'grid' packages.

Examples

if (FALSE) { # \dontrun{
# First set the brand theme to load configuration
brand_set_ggplot()

# Create a plot and add logo
library(ggplot2)
ggplot(mtcars, aes(x = mpg, y = wt)) +
  geom_point() +
  labs(title = "Example Plot") +
  brand_add_logo()

# Customize logo position and size
ggplot(mtcars, aes(x = mpg, y = wt)) +
  geom_point() +
  labs(title = "Example Plot") +
  brand_add_logo(x = 0.1, y = 0.9, size = 0.08)
