    Returns the CID for the given GID.
    int
    getGIDForCID(int cid)
    Returns the GID for a given CID.
    int
    getGIDForSID(int sid)
    Returns the GID for the given SID.
    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.

    Returns the SID for a given GID.
    boolean
    isCIDFont()
    Indicates if the charset belongs to a CID font.

  • Method Details

      boolean isCIDFont()
      Indicates if the charset belongs to a CID font.
      Returns:
      true for CID fonts

    • addSID

      void addSID(int gid, int sid, String name)
      Adds a new GID/SID/name combination to the charset.
      Parameters:
      gid - GID
      sid - SID
      name - the postscript name of the glyph

    • addCID

      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

      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

      String getNameForGID(int gid)
      Returns the PostScript glyph name for the given GID.
      Parameters:
      gid - GID
      Returns:
      PostScript glyph name

    • getCIDForGID

      int getCIDForGID(int gid)
      Returns the CID for the given GID.
      Parameters:
      gid - GID
      Returns:
      CID
