toUnicodeString

public static String toUnicodeString(byte[] bytes,
                                     int start,
                                     int length)
                              throws PDFParseException

Make a Unicode string from a byte array

Throws:

PDFParseException

toEscapeString

public static String toEscapeString(byte[] bytes,
                                    int start,
                                    int length)

Converts the byte array to escaped string.

fromEscapeString

public static byte[] fromEscapeString(String str)

Converts escaped string to a byte array.

fromUnicodeString

public static byte[] fromUnicodeString(String uniStr)

Converts a unicode string to byte array.

fromUnicodeString

public static byte[] fromUnicodeString(String uniStr,
                                       boolean utf16)

decode

public static char[] decode(byte[] bytes,
                            int start,
                            int length)
                     throws CharacterCodingException

PDFDocEncoding-encoded bytes to string conversion.

Throws:

CharacterCodingException - the byte stream is not a legal encoding.

encode

public static byte[] encode(String s)
                     throws CharacterCodingException

String to PDFDocEncoding-encoded bytes conversion.

Throws:

CharacterCodingException - the input string contains a characters which is not in PDFDocEncoding.

isUnicode

public static boolean isUnicode(String uniStr)

Returns true if passed string represents unicode, else false.

isPDFDocEncoding

public static boolean isPDFDocEncoding(String uniStr)

convertUTF16ToPDFDocEncoding

public static void convertUTF16ToPDFDocEncoding(byte[] input,
                                                EncodedData<char[]> encInfo)

Tries to convert the UTF-16 bytes passed to PDF Doc encoding. This method copies the logic of ASTextGetPDTextCopy method in ASText.cpp file of Acrobat.

Parameters:
