    • instructions

      private byte[] instructions
      the instructions

    • flags

      private byte[] flags
      the flags

    • xCoords

      private short[] xCoords
      the x coordinates

    • yCoords

      private short[] yCoords

  • Constructor Details

    • GlyfSimple

      protected GlyfSimple()
      Creates a new instance of a simple glyf

  • Method Details

    • setData

      public void setData(ByteBuffer data)
      Set the data for this glyf.
      Overrides:
      setData in class Glyf

    • 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.
      Overrides:
      getData in class Glyf

    • getLength

      public short getLength()
      Get the length of this glyf.
      Overrides:
      getLength in class Glyf

    • getContourEndPoint

      public short getContourEndPoint(int index)
      Get the end point of a given contour

    • setContourEndPoints

      protected void setContourEndPoints(short[] contourEndPts)
      Set the number of contours in this glyf

    • getNumInstructions

      public short getNumInstructions()
      Get the number of instructions

    • getInstruction

      public byte getInstruction(int index)
      Get a given instruction

    • setInstructions

      protected void setInstructions(byte[] instructions)
      Set the instructions

    • getNumPoints

      public short getNumPoints()

    • onCurve

      public boolean onCurve(int pointIndex)
      Determine whether the given point is on the curve

    • xIsByte

      protected boolean xIsByte(int pointIndex)

    • xIsSame

      protected boolean xIsSame(int pointIndex)
      Determine whether the x value for the given point is the same as the previous value.

    • yIsSame

      protected boolean yIsSame(int pointIndex)
      Determine whether the y value for the given point is the same as the previous value.
