◆ DecodeToGid()

ASPOSE_FONT_SHARED_API System::SharedPtr<Aspose::Font::Glyphs::GlyphId> Aspose::Font::Ttf::TtfEncoding::DecodeToGid ( uint32_t  unicode)
overridevirtual

TTF Font's DecodeToGlyphId implementation finds unicode table and returns glyph id for unicode char. Glyph id is a unique number for a glyph, which is font type dependent. For example: Type1's id is a glyph name, instance of (GlyphStringId) class. TTF's id is an int index, instance of (GlyphUInt32Id) class.

Parameters
unicodeCharacter code to get glyph identifier for.
Returns
Glyph identifier related to character code passed.

Implements Aspose::Font::IFontEncoding.

◆ DecodeToGidParameterized()

ASPOSE_FONT_SHARED_API System::SharedPtr<Aspose::Font::Glyphs::GlyphId> Aspose::Font::Ttf::TtfEncoding::DecodeToGidParameterized ( System::SharedPtr< IEncodingParameters parameters,
uint32_t  charCode 
)
overridevirtual

Parametrized version allows to use specific CMap table (not unicode).

Parameters
parametersImplementation of IEncodingParametersinterface.
charCodeCharacter code to get glyph identifier for.
Returns
Glyph identifier related to character code passed.

Implements Aspose::Font::IFontEncoding.

◆ Encode()

ASPOSE_FONT_SHARED_API void Aspose::Font::Ttf::TtfEncoding::Encode ( uint32_t  gid,
uint32_t  charCode 
)
overridevirtual

Encodes the glyph. For TTF Fonts the character code is unicode.

Parameters
gidGlyph identifier.
charCodeCharacter code.

Implements Aspose::Font::IFontEncoding.

◆ GidToUnicode()

ASPOSE_FONT_SHARED_API uint32_t Aspose::Font::Ttf::TtfEncoding::GidToUnicode ( System::SharedPtr< Aspose::Font::Glyphs::GlyphId glyphId)
override

Decodes glyph id to unicode. Glyph id is a unique number for a glyph, which is font type dependent. For example: Type1's id is a glyph name, instance of (GlyphStringId) class. TTF's id is an int index, instance of (GlyphUInt32Id) class.

Parameters
glyphIdGlyph identifier of symbol to decode.
Returns
Unicode value related to glyph id passed.

◆ UnicodeToGid()

ASPOSE_FONT_SHARED_API System::SharedPtr<Aspose::Font::Glyphs::GlyphId> Aspose::Font::Ttf::TtfEncoding::UnicodeToGid ( uint32_t  unicode)
overridevirtual

Decodes a unicode and returns glyph id.

Parameters
unicodeUnicode to get glyph identifier for.
Returns
Glyph identifier related to unicode passed.

Implements Aspose::Font::IFontEncoding.
