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 [Font]s 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. [b]Note:[/b] A character is a symbol that represents an item (letter, digit etc.) in an abstract way. [b]Note:[/b] A glyph is a bitmap or a shape used to draw one or more characters in a context-dependent manner. Glyph indices are bound to the specific font data source. [b]Note:[/b] If none of the font data sources contain glyphs for a character used in a string, the character in question will be replaced with a box displaying its hexadecimal code.

- If set to [code]true[/code], system fonts can be automatically used as fallbacks.
- Font anti-aliasing mode.
- Contents of the dynamic font source file.
- If set to [code]true[/code], embedded font bitmap loading is disabled (bitmap-only and color fonts ignore this property).
- Font size, used only for the bitmap fonts.
- Scaling mode, used only for the bitmap fonts with [member fixed_size] greater than zero.
- Font family name.
- Font stretch amount, compared to a normal width. A percentage value between [code]50%[/code] and [code]200%[/code].
- Font style flags.
- Weight (boldness) of the font. A value in the [code]100...999[/code] range, normal font weight is [code]400[/code], bold font weight is [code]700[/code].
- If set to [code]true[/code], auto-hinting is supported and preferred over font built-in hinting. Used by dynamic fonts only (MSDF fonts don't support hinting).
- If set to [code]true[/code], generate mipmaps for the font textures.
- Font hinting mode. Used by dynamic fonts only.
- If set to [code]true[/code], when aligning glyphs to the pixel boundaries rounding remainders are accumulated to ensure more uniform glyph distribution. This setting has no effect if subpixel positioning is enabled.
- If set to [code]true[/code], color modulation is applied when drawing colored glyphs, otherwise it's applied to the monochrome glyphs only.
- The width of the range around the shape between the minimum and maximum representable signed distance. If using font outlines, [member msdf_pixel_range] must be set to at least [i]twice[/i] the size of the largest font outline. The default [member msdf_pixel_range] value of [code]16[/code] allows outline sizes up to [code]8[/code] to look correct.
- 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.
- If set to [code]true[/code], 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 [Control]s that are scaled down (or for [Label3D]s 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. [b]Note:[/b] If using font outlines, [member msdf_pixel_range] must be set to at least [i]twice[/i] the size of the largest font outline. [b]Note:[/b] 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.
- Font OpenType feature set override.
- If set to a positive value, overrides the oversampling factor of the viewport this font is used in. See [member Viewport.oversampling]. This value doesn't override the [code skip-lint]oversampling[/code] parameter of [code skip-lint]draw_*[/code] methods.
- Font style name.
- 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 [constant TextServer.SUBPIXEL_POSITIONING_AUTO] to automatically enable it based on the font size.
