      • toCID

        public int toCID​(int character)
        Gets CID for given character.
        Parameters:
        character - is code of character, for which CID is calculated.
        Returns:
        CID for given character or 0 if it cannot be obtained.

      • containsCode

        public boolean containsCode​(int character)
        Returns:
        true if this CMap can convert given code to CID.

      • getCodeFromStream

        public int getCodeFromStream​(InputStream stream)
                      throws IOException
        Reads character code from input stream and returnes it's CID. This uses codespace information from CMap. Details are described in PDF32000 in 9.7.6.2 "CMap Mapping".
        Parameters:
        stream - is stream from which character codes will be read.
        Returns:
        CID of read code.
        Throws:
        IOException

      • useCMap

        public void useCMap​(CMap another)
        Method adds all the data needed to this CMap from another CMap.
        Parameters:
        another - is another CMap.

      • getwMode

        public int getwMode()
        Returns:
        writing mode of given CMap.

      • getRegistry

        public String getRegistry()
        Returns:
        Registry value from CIDSystemInfo dictionary.

      • getOrdering

        public String getOrdering()
        Returns:
        Ordering value from CIDSystemInfo dictionary.

      • getSupplement

        public int getSupplement()
        Returns:
        supplement of CMap.

      • setSupplement

        public void setSupplement​(int supplement)

      • isUsesNonPredefinedCMap

        public boolean isUsesNonPredefinedCMap()
        Returns:
        true if this CMap references non-predefined CMap with usecmap operator.

      • setUsesNonPredefinedCMap

        public void setUsesNonPredefinedCMap​(boolean usesNonPredefinedCMap)
        Sets indicator for CMap to contain reference to a non-predefined CMap.

      • getUnicode

        public String getUnicode​(int code)
        Returns Unicode sequence for given character code.
        Parameters:
        code - is code of character.
        Returns:
        Unicode sequence obtained from this CMap.

      • getName

        public String getName()
        Returns:
        name of this CMap.
