glyph_info: 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
)

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

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
