  • Field Details

    • origLength

      private int origLength

    • ttfData

      private byte[] ttfData

  • Constructor Details

    • PDFTTFStream

      public PDFTTFStream(int len)
      Main constructor
      Parameters:
      len - original length

  • Method Details

    • 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
      Specified by:
      output in interface CompressedObject
      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
