Struct CharacterMapping

Namespace

Egami.Fonts

Assembly

Egami.Fonts.dll

A code and the glyph a CharacterMap gives it.

public readonly record struct CharacterMapping : IEquatable<CharacterMapping>

Implements

IEquatable<CharacterMapping>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Examples

// A symbolic TrueType font in PDF looks a code up in (3,0) first, then (1,0); a non-symbolic one uses (3,1).
CharacterMap? map = trueType.FindCharacterMap(3, 0) ?? trueType.FindCharacterMap(1, 0) ?? trueType.FindCharacterMap(3, 1);
ushort forA = map?.GetGlyph('A') ?? 0;

// A Type1C font without /Encoding uses the CFF program's own encoding.
CharacterMap? own = face.BuiltInEncoding;                  // platform 7, encoding 0: the Standard Encoding
ushort forB = own?.GetGlyph('B') ?? 0;

// Every code the map gives a glyph, in code order, for a PDF writer's /Widths or a ToUnicode table.
int mapped = map?.GetMappings().Count() ?? 0;
