Types

• GlyphData: A GlyphData represents a drawable symbol of a font Rasterizer.

  • love.GlyphData.getAdvance() -> advance: number: Gets glyph advance.
  • love.GlyphData.getBearing() -> bx: number, by: number: Gets glyph bearing.
  • love.GlyphData.getBoundingBox() -> x: number, y: number, width: number, height: number: Gets glyph bounding box.
  • love.GlyphData.getDimensions() -> width: number, height: number: Gets glyph dimensions.
  • love.GlyphData.getFormat() -> format: PixelFormat: Gets glyph pixel format.
  • love.GlyphData.getGlyph() -> glyph: number: Gets glyph number.
  • love.GlyphData.getGlyphString() -> glyph: string: Gets glyph string.
  • love.GlyphData.getHeight() -> height: number: Gets glyph height.
  • love.GlyphData.getWidth() -> width: number: Gets glyph width.

• Rasterizer: A Rasterizer handles font rendering, containing the font data (image or TrueType font) and drawable glyphs.

  • love.Rasterizer.getAdvance() -> advance: number: Gets font advance.
  • love.Rasterizer.getAscent() -> height: number: Gets ascent height.
  • love.Rasterizer.getDescent() -> height: number: Gets descent height.
  • love.Rasterizer.getGlyphCount() -> count: number: Gets number of glyphs in font.
  • love.Rasterizer.getGlyphData(glyph: string) -> glyphData: GlyphData: Gets glyph data of a specified glyph.
  • love.Rasterizer.getHeight() -> height: number: Gets font height.
  • love.Rasterizer.getLineHeight() -> height: number: Gets line height of a font.
  • love.Rasterizer.hasGlyphs(glyph1: string or number, ...: string or number) -> hasGlyphs: boolean: Checks if font contains specified glyphs.

Enums

• HintingMode: True Type hinting mode.
  • normal: Default hinting. Should be preferred for typical antialiased fonts.
  • light: Results in fuzzier text but can sometimes preserve the original glyph shapes of the text better than normal hinting.
  • mono: Results in aliased / unsmoothed text with either full opacity or completely transparent pixels. Should be used when antialiasing is not desired for the font.
  • none: Disables hinting for the font. Results in fuzzier text.

Examples

Loading and using fonts

-- Load a font file
local font = love.graphics.newFont("arial.ttf", 24)

-- Set as default font
love.graphics.setFont(font)

-- Draw text
love.graphics.print("Hello World!", 100, 100)

Text formatting

-- Create fonts with different styles
local titleFont = love.graphics.newFont(36)
local bodyFont = love.graphics.newFont(18)
local boldFont = love.graphics.newFont("bold.ttf", 20)

function love.draw()
  love.graphics.setFont(titleFont)
  love.graphics.print("Game Title", 100, 50)

  love.graphics.setFont(bodyFont)
  love.graphics.printf("This is a paragraph of text that will be wrapped to fit within the specified width.", 100, 150, 400, "left")

  love.graphics.setFont(boldFont)
  love.graphics.print("Important Message!", 100, 300)
end

Best practices

• Load fonts during initialization to avoid runtime delays
• Use appropriate font sizes for different screen resolutions
• Consider memory usage when loading multiple fonts
• Handle font loading errors gracefully
• Test text rendering on target platforms

Platform compatibility

• Desktop (Windows, macOS, Linux): Full font support
• Mobile (iOS, Android): Full support with some font limitations
• Web: Good support but some fonts may not be available
