                              throws PDFParseException

Converts byte array to unicode string.

Throws:

PDFParseException

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.

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.

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:

input -

encInfo - This is the encoding information of the output.

encToUCSStrInternal

public static void encToUCSStrInternal(EncodedData<char[]> inputEncInfo,
 EncodedData<byte[]> outputEncInfo)

This method converts PDF Doc encoded data to UCS format. Logic is copied from EncToUCSStrInternal method in PDConvrt.cpp file of Acrobat.

Parameters:

inputEncInfo -

outputEncInfo -
