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.
(package private) int	getGIDForSID(int sid)	Returns the GID for the given SID.
String	getNameForGID(int gid)	Returns the PostScript glyph name for the given GID.
(package private) 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.

Constructor Details

CFFCharset

CFFCharset(boolean isCIDFont)

Package-private constructor for use by subclasses.

Parameters:

isCIDFont - true if the parent font is a CIDFont

Method Details

isCIDFont

public boolean isCIDFont()

Indicates if the charset belongs to a CID font.

Returns:

true for CID fonts

addSID

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

Adds a new GID/SID/name combination to the charset.

Parameters:

gid - GID

sid - SID

addCID

public void addCID(int gid,
 int cid)

Adds a new GID/CID combination to the charset.

Parameters:

gid - GID

cid - CID

getSIDForGID

int getSIDForGID(int gid)

Returns the SID for a given GID. SIDs are internal to the font and are not public.

Parameters:

gid - GID

Returns:

SID

getGIDForSID

int getGIDForSID(int sid)

Returns the GID for the given SID. SIDs are internal to the font and are not public.

Parameters:

sid - SID

Returns:

GID

getGIDForCID

public int getGIDForCID(int cid)

Returns the GID for a given CID. Returns 0 if the CID is missing.

Parameters:

cid - CID

Returns:

GID

getSID

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.

Parameters:

name - PostScript glyph name

Returns:

SID

getNameForGID

public String getNameForGID(int gid)

Returns the PostScript glyph name for the given GID.

Parameters:

gid - GID

Returns:

PostScript glyph name

getCIDForGID

public int getCIDForGID(int gid)

Returns the CID for the given GID.

Parameters:

gid - GID

Returns:

CID
