      Creates a new instance of a simple glyf

  • Method Details

    • getData

      public ByteBuffer getData()
      Get the data in this glyf as a byte buffer. Return the basic glyf data only, since there is no specific data. This method returns the data un-flipped, so subclasses can simply append to the allocated buffer.

      Get the data in this glyf as a byte buffer. Return the basic glyf data only, since there is no specific data. This method returns the data un-flipped, so subclasses can simply append to the allocated buffer.

      Overrides:
      getData in class Glyf
      Returns:
      a ByteBuffer object.

    • setData

      public void setData(ByteBuffer data)
      Set the data for this glyf. Do nothing, since a glyf with no contours has no glyf data.

      Set the data for this glyf.

      Overrides:
      setData in class Glyf
      Parameters:
      data - a ByteBuffer object.

    • getLength

      public short getLength()
      Get the length of this glyf. A glyf with no data has a length of 10 (2 bytes each for 5 short values)

      Get the length of this glyf.

      Overrides:
      getLength in class Glyf
      Returns:
      a short.
