Method Detail

gidToUnicode

public long gidToUnicode(GlyphId glyphId)

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.

Specified by:

gidToUnicode in interface IFontEncoding

Parameters:

glyphId - Glyph identifier of symbol to decode.

Returns:

Unicode value related to glyph id passed.

encode

public void encode(long gid,
                   long charCode)

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

Specified by:

encode in interface IFontEncoding

Parameters:

gid - Glyph identifier.

charCode - Character code.

unicodeToGid

public GlyphId unicodeToGid(long unicode)

Decodes a unicode and returns glyph id.

Specified by:

unicodeToGid in interface IFontEncoding

Parameters:

unicode - Unicode to get glyph identifier for.

Returns:

Glyph identifier related to unicode passed.

decodeToGid

public GlyphId decodeToGid(long unicode)

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.

Specified by:

decodeToGid in interface IFontEncoding

Parameters:

unicode - Character code to get glyph identifier for.

Returns:

Glyph identifier related to character code passed.

decodeToGidParameterized

public GlyphId decodeToGidParameterized(IEncodingParameters parameters,
                                        long charCode)

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

Specified by:

decodeToGidParameterized in interface IFontEncoding

Parameters:

parameters - Implementation of IEncodingParameters interface.

charCode - character code to get glyph identifier for.

Returns:

Glyph identifier related to character code passed.
