Method Summary

Modifier and Type	Method	Description
void	addCID(int gid, int cid)	Adds a new GID/CID combination to the charset.
void	addSID(int gid, int sid, String name)	Adds a new GID/SID/name combination to the charset.
int	getCIDForGID(int gid)	Returns the CID for the given GID.
int	getGIDForCID(int cid)	Returns the GID for a given CID.

String	getNameForGID(int gid)	Returns the PostScript glyph name for the given GID.
int	getSID(String name)	Returns the SID for a given PostScript name, you would think this is not needed, but some fonts have glyphs beyond their encoding with charset SID names.
int	getSIDForGID(int gid)	Returns the SID for a given GID.

Returns:

true for CID fonts

addSID

public void addSID(int gid,
 int sid,
 String name)

Description copied from interface: CFFCharset

addCID

public void addCID(int gid,
 int cid)

Description copied from interface: CFFCharset

Adds a new GID/CID combination to the charset.
