browser_print {xfun}R Documentation

Print a web page to PDF/PNG/JPEG

Description

Print a web page to PDF or take a screenshot to PNG/JPEG via a headless browser such as Chromium or Google Chrome.

Usage

browser_print(
  input,
  output = ".pdf",
  args = "default",
  window_size = c(1280, 1024),
  browser = env_option("xfun.browser", find_browser())
)

Arguments

input

Path or URL to the HTML page to be printed.

output

An output filename. If only an extension is provided, the filename will be inferred from url via url_filename(). Only .pdf, .png, and .jpeg are supported.

args

Command-line arguments to be passed to the headless browser. The default arguments can be found in xfun:::browser_args(). You may pass additional arguments on top of these via, e.g., c('default', '--no-pdf-header-footer'), or completely override the default arguments by providing a vector of other arguments.

window_size

The browser window size when taking a PNG/JPEG screenshot. Ignored when printing to PDF.

browser

Path to the web browser. By default, the browser is found via xfun:::find_browser(). If it cannot be found, you may set the global option options(xfun.browser = ) or environment variable R_XFUN_BROWSER to the path of the browser, or simply pass the path to the browser argument.

Value

The output path if the web page is successfully printed.
