string_metrics_dev: Get string metrics as measured by the current device

In systemfonts: System Native Font Finding

Get string metrics as measured by the current device

Description

This function is much like string_widths_dev() but also returns the ascent and descent of the string making it possible to construct a tight bounding box around the string.

Usage

string_metrics_dev(
  strings,
  family = "",
  face = 1,
  size = 12,
  cex = 1,
  unit = "cm"
)

Arguments

strings	A character vector of strings to measure
family	The font families to use. Will get recycled
face	The font faces to use. Will get recycled
size	The font size to use. Will get recycled
cex	The cex multiplier to use. Will get recycled
unit	The unit to return the width in. Either "cm", "inches", "device", or "relative"

Value

A data.frame with width, ascent, and descent columns giving the metrics in the requested unit.
