string_width

Calculate the width of a string, ignoring new-lines

Description

This is a very simple alternative to shape_string() that simply calculates the width of strings without taking any newline into account. As such it is suitable to calculate the width of words or lines that has already been splitted by \n. Input is recycled to the length of strings.

Usage

string_width(
  strings,
  family = "",
  italic = FALSE,
  bold = FALSE,
  size = 12,
  res = 72,
  include_bearing = TRUE,
  path = NULL,
  index = 0
)

Arguments

`strings`	A character vector of strings
`family`	The name of the font family
`italic`	logicals indicating the font style
`bold`	logicals indicating the font style
`size`	The pointsize of the font to use for size related measures
`res`	The ppi of the size related mesures
`include_bearing`	Logical, should left and right bearing be included in the string width?
`path`	path an index of a font file to circumvent lookup based on family and style
`index`	path an index of a font file to circumvent lookup based on family and style

Value

A numeric vector giving the width of the strings in pixels. Use the provided res value to convert it into absolute values.

Examples

strings <- c('A short string', 'A very very looong string')
string_width(strings)
