<brief_description>
|
|
Font source data and prerendered glyph cache, imported from dynamic or bitmap font.
|
|
</brief_description>
|
|
<description>
|
|
[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 shape used to draw a one or more characters in a context-dependent manner. Glyph indices are bound to the specific font data source.
|
|
[b]Note:[/b] If a 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.
