Holds font source data and prerendered glyph cache, imported from a dynamic or a bitmap font.

FontFile contains a set of glyphs to represent Unicode characters imported from a font file, as well as a cache of rasterized glyphs, and a set of fallback Fonts to use.

Use FontVariation to access specific OpenType variation of the font, create simulated bold / slanted version, and draw lines of text.

For more complex text processing, use FontVariation in conjunction with TextLine or TextParagraph.

Supported font formats:

  • Dynamic font importer: TrueType (.ttf), TrueType collection (.ttc), OpenType (.otf), OpenType collection (.otc), WOFF (.woff), WOFF2 (.woff2), Type 1 (.pfb, .pfm).

  • Bitmap font importer: AngelCode BMFont (.fnt, .font), text and binary (version 3) format variants.

  • Monospace image font importer: All supported image formats.

var f = load("res://BarlowCondensed-Bold.ttf") $Label.add_theme_font_override("font", f) $Label.add_theme_font_size_override("font_size", 64)
bool allow_system_fallback<>():bool

If set to true, system fonts can be automatically used as fallbacks.

 FontAntialiasing antialiasing<>():FontAntialiasing

Font anti-aliasing mode.

 PackedByteArray data<>():PackedByteArray

Contents of the dynamic font source file.

 int fixed_size<>():int

Font size, used only for the bitmap fonts.

 FixedSizeScaleMode fixed_size_scale_mode<>():FixedSizeScaleMode

Scaling mode, used only for the bitmap fonts with fixed_size greater than zero.

 String font_name<>():String

Font family name.

 int font_stretch<>():int

Font stretch amount, compared to a normal width. A percentage value between 50% and 200%.

 BitField FontStyle<>():BitField

Font style flags, see FontStyle.

 int font_weight<>():int

Weight (boldness) of the font. A value in the 100...999 range, normal font weight is 400, bold font weight is 700.

 bool force_autohinter<>():bool

If set to true, auto-hinting is supported and preferred over font built-in hinting. Used by dynamic fonts only (MSDF fonts don't support hinting).

 bool generate_mipmaps<>():bool

If set to true, generate mipmaps for the font textures.

 Hinting hinting<>():Hinting

Font hinting mode. Used by dynamic fonts only.

 int msdf_pixel_range<>():int

The width of the range around the shape between the minimum and maximum representable signed distance. If using font outlines, msdf_pixel_range must be set to at least twice the size of the largest font outline. The default msdf_pixel_range value of 16 allows outline sizes up to 8 to look correct.

 int msdf_size<>():int

Source font size used to generate MSDF textures. Higher values allow for more precision, but are slower to render and require more memory. Only increase this value if you notice a visible lack of precision in glyph rendering.

 bool multichannel_signed_distance_field<>():bool

If set to true, glyphs of all sizes are rendered using single multichannel signed distance field (MSDF) generated from the dynamic font vector data. Since this approach does not rely on rasterizing the font every time its size changes, this allows for resizing the font in real-time without any performance penalty. Text will also not look grainy for Controls that are scaled down (or for Label3Ds viewed from a long distance). As a downside, font hinting is not available with MSDF. The lack of font hinting may result in less crisp and less readable fonts at small sizes.

Note: If using font outlines, msdf_pixel_range must be set to at least twice the size of the largest font outline.

Note: MSDF font rendering does not render glyphs with overlapping shapes correctly. Overlapping shapes are not valid per the OpenType standard, but are still commonly found in many font files, especially those converted by Google Fonts. To avoid issues with overlapping glyphs, consider downloading the font file directly from the type foundry instead of relying on Google Fonts.

 Dictionary opentype_feature_overrides<>():Dictionary

Font OpenType feature set override.

 float oversampling<>():float

Font oversampling factor. If set to 0.0, the global oversampling factor is used instead. Used by dynamic fonts only (MSDF fonts ignore oversampling).

 String style_name<>():String

Font style name.

 SubpixelPositioning subpixel_positioning<>():SubpixelPositioning

Font glyph subpixel positioning mode. Subpixel positioning provides shaper text and better kerning for smaller font sizes, at the cost of higher memory usage and lower font rasterization speed. Use TextServer.SUBPIXEL_POSITIONING_AUTO to automatically enable it based on the font size.
