Batch convert SVGs to PNG base64 using headless Chrome — batch_svg_to_base64

Converts multiple SVGs to base64-encoded PNG strings using a single Chrome session. Much faster than calling svg_to_png_chrome() repeatedly.

Usage

batch_svg_to_base64_chrome(
  svg_list,
  dpi = 300,
  background = "transparent",
  load_wait = 0.5,
  restart_every = 50,
  retry_attempts = 3,
  progress = TRUE
)

Arguments

svg_list: List of SVG strings or file paths.
dpi: Resolution (default 300).
background: Background color (default "transparent").
load_wait: Seconds to wait for each page to load (default 0.5). Increase if conversions are failing.
restart_every: Restart Chrome session every N conversions (default 50). Helps prevent memory issues and stale connections.
retry_attempts: Number of retry attempts on failure (default 3).
progress: Show progress bar (default TRUE).

Value

Character vector of base64-encoded PNGs (data URI format). Returns NA for failed conversions.
