### Constructor Detail

#### PDFTTFStream

    public PDFTTFStream(int len)

Main constructor

Parameters:
  `len` - original length

### Method Detail

#### getSizeHint

    protected int getSizeHint()
                       throws IOException

Returns a value that hints at the size of the encoded stream. This is used to optimize buffer allocation so fewer buffer reallocations are necessary.

Specified by:
  `getSizeHint` in class `AbstractPDFStream`
Returns:
  an estimated size (0 if no hint can be given)
Throws:
  `IOException` - in case of an I/O problem

#### output

    public int output(OutputStream stream)
               throws IOException

Overload the base object method so we don't have to copy byte arrays around so much Overload the base object method so we don't have to copy byte arrays around so much Write the PDF represention of this object

Overrides:
  `output` in class `AbstractPDFStream`
Parameters:
  `stream` - the stream to write the PDF to
Returns:
  the number of bytes written
Throws:
  `IOException` - if there is an error writing to the stream

#### outputRawStreamData

    protected void outputRawStreamData(OutputStream out)
                                throws IOException

Sends the raw stream data to the target OutputStream.

Specified by:
  `outputRawStreamData` in class `AbstractPDFStream`
Parameters:
  `out` - OutputStream to write to
Throws:
  `IOException` - In case of an I/O problem

#### populateStreamDict

    protected void populateStreamDict(Object lengthEntry)

Populates the dictionary with all necessary entries for the stream. Override this method if you need additional entries.

Overrides:
  `populateStreamDict` in class `AbstractPDFStream`
Parameters:
  `lengthEntry` - value for the /Length entry

#### setData

    public void setData(byte[] data,
                        int size)
                 throws IOException

Sets the TrueType font data.

Parameters:
  `data` - the font payload
  `size` - size of the payload
Throws:
  `IOException` - in case of an I/O problem
