public interface IFontEncoding

Defines an interface for Font encoding.

Method Summary

Modifier and Type	Method and Description
GlyphId	decodeToGid(long charCode) Decodes a character code and returns glyph id.
GlyphId	decodeToGidParameterized(IEncodingParameters parameters, long charCode) Parameterized decode method.
void	encode(long gid, long charCode) Encodes the glyph.
long	gidToUnicode(GlyphId gid) Decodes Gid to unicode.
GlyphId	unicodeToGid(long unicode) Decodes a unicode and returns glyph id.

Method Detail

gidToUnicode

long gidToUnicode(GlyphId gid)

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:

gid - Glyph identifier of symbol to decode.

Returns:

Unicode value related to glyph id passed.

encode

void encode(long gid,
            long charCode)

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

Parameters:

gid - Glyph id.

charCode - Character code associated with the glyph id.

unicodeToGid

GlyphId unicodeToGid(long unicode)

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:

unicode - Unicode to get glyph identifier for.

Returns:

Glyph identifier related to unicode passed.

decodeToGid

GlyphId decodeToGid(long charCode)

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.

Parameters:

charCode - Character code to get glyph identifier for.

Returns:

Glyph identifier related to charCode passed.

decodeToGidParameterized

GlyphId decodeToGidParameterized(IEncodingParameters parameters,
                                 long charCode)

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

Parameters:

parameters - Implementation of IEncodingParameters interface.

charCode - Character code to get glyph identifier for.

Returns:

Glyph identifier related to char code passed.
