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,
  weight = "normal",
  width = "undefined",
  size = 12,
  res = 72,
  path = NULL,
  index = 0,
  variation = font_variation(),
  bold = deprecated()
)

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
weight: The weight to query for, either in numbers (0, 100, 200, 300, 400, 500, 600, 700, 800, or 900) or strings ("undefined", "thin", "ultralight", "light", "normal", "medium", "semibold", "bold", "ultrabold", or "heavy"). NA will be interpreted as "undefined"/0
width: The width to query for either in numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) or strings ("undefined", "ultracondensed", "extracondensed", "condensed", "semicondensed", "normal", "semiexpanded", "expanded", "extraexpanded", or "ultraexpanded"). NA will be interpreted as "undefined"/0
size: The pointsize of the font to use for size related measures
res: The ppi of the size related measures
path, index: path an index of a font file to circumvent lookup based on family and style
variation: A font_variation object or a list of them to control variable fonts
bold: Use weight = "bold" instead
