    • WE_HAVE_A_SCALE

      protected static final short WE_HAVE_A_SCALE
      If set, there is a simple scale; otherwise, scale = 1.0.
      See Also:

    • MORE_COMPONENTS

      protected static final short MORE_COMPONENTS
      Indicates at least one more glyph after this one.
      See Also:

    • WE_HAVE_AN_X_AND_Y_SCALE

      protected static final short WE_HAVE_AN_X_AND_Y_SCALE
      The x direction will use a different scale from the y direction.
      See Also:

    • WE_HAVE_A_TWO_BY_TWO

      protected static final short WE_HAVE_A_TWO_BY_TWO
      There is a 2 by2 transformation that will be used to scale the component.

    • WE_HAVE_INSTRUCTIONS

      protected static final short WE_HAVE_INSTRUCTIONS
      Following the last component are instructions for the composite character.
      See Also:

    • USE_MY_METRICS

      protected static final short USE_MY_METRICS
      If set, this forces the aw and lsb (and rsb) for the composite to be equal to those from this original glyph.
