Constructor Detail

### PDFText

    public PDFText()

Method Detail

### getText

    public java.lang.String getText()

  Returns the text.

  Returns:
    the text

### setText

    public void setText(java.lang.String text)

  Sets the text.

  Parameters:
    `text` - the text

### toPDFString

    protected java.lang.String toPDFString()

  This method returns a String representation of the PDF object. The result is normally converted/encoded to a byte array by toPDF(). Only use this method to implement the serialization if the object can be fully represented as text. If the PDF representation of the object contains binary content use toPDF() or output(OutputStream) instead. This applies to any object potentially containing a string object because string object are encrypted and therefore need to be binary.

  Overrides:
    `toPDFString` in class `PDFObject`
  Returns:
    String the String representation

### escapeText

    public static final java.lang.String escapeText(java.lang.String text)

  Escape text (see 4.4.1 in PDF 1.3 specs)

  Parameters:
    `text` - the text to encode
  Returns:
    encoded text

### escapeText

    public static final java.lang.String escapeText(java.lang.String text,
                                                    boolean forceHexMode)

  Escape text (see 4.4.1 in PDF 1.3 specs)

  Parameters:
    `text` - the text to encode
    `forceHexMode` - true if the output should follow the hex encoding rules
  Returns:
    encoded text

### toHex

    public static final java.lang.String toHex(byte[] data,
                                               boolean brackets)

  Converts a byte array to a Hexadecimal String (3.2.3 in PDF 1.4 specs)

  Parameters:
    `data` - the data to encode
    `brackets` - true if enclosing brackets should be included
  Returns:
    String the resulting string

### toHex

    public static final java.lang.String toHex(byte[] data)

  Converts a byte array to a Hexadecimal String (3.2.3 in PDF 1.4 specs)

  Parameters:
    `data` - the data to encode
  Returns:
    String the resulting string

### toUTF16

    public static final byte[] toUTF16(java.lang.String text)

  Converts a String to UTF-16 (big endian).

  Parameters:
    `text` - text to convert
  Returns:
    byte[] UTF-16 stream

### toUnicodeHex

    public static final java.lang.String toUnicodeHex(char c)

  Convert a char to a multibyte hex representation

  Parameters:
    `c` - character to encode
  Returns:
    the encoded character

### escapeString

    public static final java.lang.String escapeString(java.lang.String s)

  Escaped a String as described in section 4.4 in the PDF 1.3 specs.

  Parameters:
    `s` - String to escape
  Returns:
    String the escaped String

### escapeStringChar

    public static final void escapeStringChar(char c,
                                              java.lang.StringBuffer target)

  Escapes a character conforming to the rules established in the PostScript Language Reference (Search for "Literal Text Strings").

  Parameters:
    `c` - character to escape
    `target` - target StringBuffer to write the escaped character to

### escapeByteArray

    public static final byte[] escapeByteArray(byte[] data)

  Escape a byte array for output to PDF (Used for encrypted strings)

  Parameters:
    `data` - data to encode
  Returns:
    byte[] encoded data

### toPDFString

    public static java.lang.String toPDFString(java.lang.CharSequence text)

  Converts a text to PDF's "string" data type. Unsupported characters get converted to '?' characters (similar to what the Java "US-ASCII" encoding does).

  Parameters:
    `text` - the text to convert
  Returns:
    the converted string
  See Also:
    `toPDFString(CharSequence, char)`

### toPDFString

    public static java.lang.String toPDFString(java.lang.CharSequence text,
                                               char replacement)

  Converts a text to PDF's "string" data type. Unsupported characters get converted to the given replacement character.

  The PDF library currently doesn't properly distinguish between the PDF data types "string" and "text string", so we currently restrict "string" to US-ASCII, also because "string" seems somewhat under-specified concerning the upper 128 bytes.

  Parameters:
    `text` - the text to convert
    `replacement` - the replacement character used when substituting a character
  Returns:
    the converted string
