    • isPredefinedCidFont

      public static boolean isPredefinedCidFont(String fontName)
      Checks if the font with the given name and encoding is one of the predefined CID fonts.
      Parameters:
      fontName - the font name.
      Returns:
      true if it is CJKFont.

    • getCompatibleCidFont

      public static String getCompatibleCidFont(String cmap)
      Finds a CJK font family which is compatible to the given CMap.
      Parameters:
      cmap - a name of the CMap for which compatible font is searched.
      Returns:
      a CJK font name if there's known compatible font for the given cmap name, or null otherwise.

    • getCompatibleCmaps

      public static Set<String> getCompatibleCmaps(String fontName)
      Finds all CMap names that belong to the same registry to which a given font belongs.
      Parameters:
      fontName - a name of the font for which CMap's are searched.
      Returns:
      a set of CMap names corresponding to the given font.

    • getAllPredefinedCidFonts

      public static Map<String, Map<String,Object>> getAllPredefinedCidFonts()
      Get all loaded predefined CID fonts.
      Returns:
      predefined CID fonts.

    • getRegistryNames

      public static Map<String, Set<String>> getRegistryNames()
      Get all loaded CJK registry names mapped to a set of compatible cmaps.
      Returns:
      CJK registry names mapped to a set of compatible cmaps.

    • getCid2UniCmap

      public static CMapCidUni getCid2UniCmap(String uniMap)
      Parses CMap with a given name producing it in a form of cid to unicode mapping.
      Parameters:
      uniMap - a CMap name. It is expected that CMap identified by this name defines unicode to cid mapping.
      Returns:
      an object for convenient mapping from cid to unicode. If no CMap was found for provided name an exception is thrown.

    • getUni2CidCmap

      public static CMapUniCid getUni2CidCmap(String uniMap)
      Parses CMap with a given name producing it in a form of unicode to cid mapping.
      Parameters:
      uniMap - a CMap name. It is expected that CMap identified by this name defines unicode to cid mapping.
      Returns:
      an object for convenient mapping from unicode to cid. If no CMap was found for provided name an exception is thrown.

    • getByte2CidCmap

      public static CMapByteCid getByte2CidCmap(String cmap)
      Parses CMap with a given name producing it in a form of byte to cid mapping.
      Parameters:
      cmap - a CMap name. It is expected that CMap identified by this name defines byte to cid mapping.
      Returns:
      an object for convenient mapping from byte to cid. If no CMap was found for provided name an exception is thrown.

    • getCidToCodepointCmap

      public static CMapCidToCodepoint getCidToCodepointCmap(String cmap)
      Parses CMap with a given name producing it in a form of cid to code point mapping.
      Parameters:
      cmap - a CMap name. It is expected that CMap identified by this name defines code point to cid mapping.
      Returns:
      an object for convenient mapping from cid to code point. If no CMap was found for provided name an exception is thrown.

    • getCodepointToCidCmap

      public static CMapCodepointToCid getCodepointToCidCmap(String uniMap)
      Parses CMap with a given name producing it in a form of code point to cid mapping.
      Parameters:
