Convert SVG to PDF using headless Chrome — svg_to_pdf

Renders an SVG to PDF using headless Chrome via the chromote package. This method produces vector PDFs with perfect font rendering.

Usage

svg_to_pdf_chrome(
  svg_input,
  output_path,
  background = "transparent",
  print_background = TRUE,
  load_wait = 0,
  timeout = 10
)

Arguments

svg_input: SVG string or path to an SVG file.
output_path: Output path for the PDF file.
background: Background color for the HTML page (default "transparent").
print_background: Whether to include CSS backgrounds in PDF (default TRUE).
load_wait: Extra seconds to wait after the page reports ready (default 0). Readiness (fonts loaded, layout painted) is detected automatically; this is only a safety margin for edge cases.
timeout: Maximum seconds to wait for page readiness (default 10).

Value

Path to the generated PDF file.

Details

The Chrome session is kept alive and reused across calls (with an automatic health check). The PDF is only generated after document.fonts.ready resolves, ensuring web fonts are fully rendered.

Examples

if (FALSE) { # \dontrun{
svg <- svg_card("FAR", list(), list())
if (chrome_available()) {
  pdf_path <- svg_to_pdf_chrome(svg, tempfile(fileext = ".pdf"))
}
} # }
