Namespace DRIT.Drawing.Font.Encoding

Classes

FontEncodingDefaults

Default implementation of TryGetGlyph(uint, out uint) and HasGlyph(uint) that derives coverage from DecodeToGid(uint). Implementers that can distinguish "no cmap entry" from "cmap entry → glyph 0" should override these methods directly.

NullEncoding

A no-op encoding that always returns NotDefId. Used as a placeholder before a real CMap table is parsed.

TtfUnicodeEncoding

Implements IFontEncoding by delegating to a CMap format subtable (TtfCMapFormatBaseTable) selected from a TrueType/OpenType font's "cmap" table.

Interfaces

IFontEncoding

Maps Unicode code points (and characters) to glyph identifiers within a font. Typically backed by a CMap subtable selected from the font's "cmap" table.
