Member Function Documentation

◆ DecodeToGid()

virtual System::SharedPtr<Glyphs::GlyphId> Aspose::Font::IFontEncoding::DecodeToGid ( uint32_t  charCode)
pure virtual

Decodes a character code and returns glyph id. 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. Note: character code is not necessary a unicode. Character code is a char index in Font encoding "table".

Parameters
charCodeCharacter code to get glyph identifier for.
Returns
Glyph identifier related to charCode passed.

Implemented in Aspose::Font::Type1::Type1Encoding, Aspose::Font::Cff::CffEncoding, and Aspose::Font::Ttf::TtfEncoding.

◆ DecodeToGidParameterized()

virtual System::SharedPtr<Glyphs::GlyphId> Aspose::Font::IFontEncoding::DecodeToGidParameterized ( System::SharedPtr< IEncodingParameters parameters,
uint32_t  charCode 
)
pure virtual

Parameterized decode method.

Some font types can have multiple encoding algorithms/maps. So, IEncodingParameters interface is used to create concrete font encoding parameters.

Parameters
parametersImplementation of IEncodingParameters interface.
charCodeCharacter code to get glyph identifier for.
Returns
Glyph identifier related to char code passed.

Implemented in Aspose::Font::Type1::Type1Encoding, Aspose::Font::Cff::CffEncoding, and Aspose::Font::Ttf::TtfEncoding.

◆ Encode()

virtual void Aspose::Font::IFontEncoding::Encode ( uint32_t  gid,
uint32_t  charCode 
)
pure virtual

Encodes the glyph. For TTF Fonts the charCode is unicode.

Parameters
gidGlyph id.
charCodeCharacter code associated with the glyph id.

Implemented in Aspose::Font::Type1::Type1Encoding, Aspose::Font::Cff::CffEncoding, and Aspose::Font::Ttf::TtfEncoding.

◆ GidToUnicode()

virtual uint32_t Aspose::Font::IFontEncoding::GidToUnicode ( System::SharedPtr< Glyphs::GlyphId gid)
pure virtual

Decodes Gid 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
gidGlyph identifier of symbol to decode.
Returns
Unicode value related to glyph id passed.

◆ UnicodeToGid()

virtual System::SharedPtr<Glyphs::GlyphId> Aspose::Font::IFontEncoding::UnicodeToGid ( uint32_t  unicode)
pure virtual

Decodes a unicode and returns glyph id. 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
unicodeUnicode to get glyph identifier for.
Returns
Glyph identifier related to unicode passed.

Implemented in Aspose::Font::Type1::Type1Encoding, Aspose::Font::Cff::CffEncoding, and Aspose::Font::Ttf::TtfEncoding.
