Overview

This report presents a reproducible workflow for generating QR codes in R.

You can also use the qr_code() function from the rutils package to automate the process.

For more details about the implementation, see the README in the code repository.

If you find this project useful, please consider giving it a star!

Set the Environment

Load Packages

library(here)
library(magick)
library(qrcode)
library(rsvg)

Set Initial Variables

link <- "https://github.com/danielvartan"

logo <- here("images", "github-icon.svg")

frame <- here("images", "qr-code-frame.svg")

Generate the QR Code

qr_code <- link |> qr_code(ecl = "H")

qr_code |>
  generate_svg(
    filename = here("images", "qr-code.svg"),
    size = 530,
    show = FALSE
  )

Add a Logo

qr_code |>
  add_logo(logo = logo, ecl = "L") |>
  generate_svg(
    filename = here("images", "qr-code-with-logo.svg"),
    size = 530,
    show = FALSE
  )

Add a Frame

qr_code <-
  here("images", "qr-code-with-logo.svg") |>
  image_read() |>
  image_trim() |>
  image_resize("450x450!")

image_info(qr_code)

frame <-
  frame |>
  image_read_svg(width = 550, height = 650)

image_info(frame)

composite <- image_composite(
  image = frame,
  composite_image = qr_code,
  offset = "+50 +50"
)

image_info(composite)

composite |>
  image_write(
    path = here("images", "qr-code-composite.png"),
    format = "png",
    quality = 100
  )
