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
