Fonts

Fonts#

EG-Overlay uses FreeType2 to render font glyphs on screen. This means that any font that FreeType2 supports can be used, however, module authors are encouraged to use the default fonts detailed below.

Fonts can be accessed using the getfont() function in the eg-overlay-ui module.

Default Fonts#

EG-Overlay comes with 3 default fonts:

Each of the above fonts are initialized with default values and can be accessed in a fonts table on the eg-overlay-ui module as regular, monospace, and icon.

Example#
local ui = require 'eg-overlay-ui'

local regfont = ui.fonts.regular
local monofont = ui.fonts.monospace
local iconfont = ui.fonts.icon

Functions#

eg-overlay-ui.getfont(path, size[, vars])#

Get a font.

If the font hasn’t been loaded yet, it will be initialized first.

Parameters:

  • path (string) – The path to the font file.

  • size (integer) – The font height in pixels.

  • vars (table) – (Optional) A table of font variable values, such as wght.

Return type:

uifont

Example#
local ui = require 'eg-overlay-ui'

local bold = ui.getfont('path/to/font.tff', 14, {wght = 900})

Note

Variables supported will differ for each font. Some fonts will not support variables at all.

Unspecified, unsupported font variables or invalid values will be ignored and be given default values.

Inter, the regular default font supports the following variables:

  • slnt: slant

  • wght: weight

CascadeCode, the monospace default font supports the following variables:

  • wght: weight

Google Material Design Icons, the icon default font supports the following variables:

  • FILL: 0 for outlined or 1 for filled icons
