Method Detail

• read

  public void read(org.apache.fontbox.ttf.TTFDataStream data,
          int version)
            throws IOException

  This will read the required data from the stream.

  Parameters:

  data - The stream to read the data from.

  version - The version of the table to be read

  Throws:

  IOException - If there is an error reading the data.

• isHorizontalKerning

  public boolean isHorizontalKerning()

  Determine if subtable is designated for use in horizontal writing modes and contains inline progression kerning pairs (not block progression "cross stream") kerning pairs.

  Returns:

  true if subtable is for horizontal kerning

• isHorizontalKerning

  public boolean isHorizontalKerning(boolean cross)

  Determine if subtable is designated for use in horizontal writing modes, contains kerning pairs (as opposed to minimum pairs), and, if CROSS is true, then return cross stream designator; otherwise, if CROSS is false, return true if cross stream designator is false.

  Parameters:

  cross - if true, then return cross stream designator in horizontal modes

  Returns:

  true if subtable is for horizontal kerning in horizontal modes

• getKerning

  public int[] getKerning(int[] glyphs)

  Obtain kerning adjustments for GLYPHS sequence, where the Nth returned adjustment is associated with the Nth glyph and the succeeding non-zero glyph in the GLYPHS sequence. Kerning adjustments are returned in font design coordinates.

  Parameters:

  glyphs - a (possibly empty) array of glyph identifiers

  Returns:

  a (possibly empty) array of kerning adjustments

• getKerning

  public int getKerning(int l,
               int r)

  Obtain kerning adjustment for glyph pair {L,R}.

  Parameters:

  l - left member of glyph pair

  r - right member of glyph pair

  Returns:

  a (possibly zero) kerning adjustment
