Query glyph-specific information from fonts

Description

This function allows you to extract information about the individual glyphs in a font, based on a specified size. All size related measures are in pixel-units. The function is vectorised to the length of the glyphs vector.

Usage

glyph_info(
  glyphs,
  family = "",
  italic = FALSE,
  bold = FALSE,
  size = 12,
  res = 72,
  path = NULL,
  index = 0
)

Arguments

`glyphs`	A vector of glyphs. Strings will be split into separate glyphs automatically
`family`	The name of the font families to match
`italic`	logical indicating the font slant
`bold`	logical indicating whether the font weight
`size`	The pointsize of the font to use for size related measures
`res`	The ppi of the size related mesures
`path`, `index`	path an index of a font file to circumvent lookup based on family and style

Value

A data.frame with information about each glyph, containing the following columns:

glyph: The glyph as a character
index: The index of the glyph in the font file
width: The width of the glyph
height: The height of the glyph
x_bearing: The horizontal distance from the origin to the leftmost part of the glyph
y_bearing: The vertical distance from the origin to the top part of the glyph
x_advance: The horizontal distance to move the cursor after adding the glyph
y_advance: The vertical distance to move the cursor after adding the glyph
bbox: The tight bounding box surrounding the glyph
