Save a ggplot Directly to a Raster Device — .save.ggplot.fast • AutoSpectral

Saves a ggplot object by opening the target device directly and printing the plot, rather than going through ggplot2::ggsave()'s own device- resolution and dimension-guessing logic. Produces the same output as ggsave(filename, plot, device = device, width = width, height = height, dpi = dpi, ...) with units = "in".

Usage

.save.ggplot.fast(
  plot,
  filename,
  width,
  height,
  dpi = 300,
  device = ragg::agg_jpeg,
  ...
)

Arguments

plot: A ggplot object.
filename: File path to save to.
width: Numeric, plot width in inches.
height: Numeric, plot height in inches.
dpi: Numeric, resolution in dots per inch. Default 300, matching ggplot2::ggsave()'s default.
device: A ragg device-opening function, e.g. ragg::agg_jpeg or ragg::agg_png. Default ragg::agg_jpeg.
...: Additional arguments passed to device(), e.g. method = "fast" or quality = for ragg::agg_jpeg().

Value

Invisibly, filename. Called for its side effect of writing the plot to disk.
