    • useKerningAdjustments

      private static boolean useKerningAdjustments(Font font, String script, String language)

    • getKerningAdjustments

      private static int[][] getKerningAdjustments(CharSequence mcs, Font font, int[][] gpa)
      Given a mapped character sequence MCS, obtain glyph position adjustments from the font's kerning data.
      Parameters:
      mcs - mapped character sequence
      font - applicable font
      Returns:
      glyph position adjustments (or null if no kerning)

    • processWordNoMapping

      private static GlyphMapping processWordNoMapping(TextFragment text, int startIndex, int endIndex, Font font, MinOptMax letterSpaceIPD, MinOptMax[] letterSpaceAdjustArray, char precedingChar, char breakOpportunityChar, boolean endsWithHyphen, int level)

    • addToLetterAdjust

      private static void addToLetterAdjust(MinOptMax[] letterSpaceAdjustArray, int index, int width)

    • isSpace

      public static boolean isSpace(char ch)
      Indicates whether a character is a space in terms of this layout manager.
      Parameters:
      ch - the character
      Returns:
      true if it's a space

    • getWordLength

      public int getWordLength()
      Obtain number of 'characters' contained in word. If word is mapped, then this number may be less than or greater than the original length (breakIndex - startIndex). We compute and memoize thius length upon first invocation of this method.

    • addToAreaIPD

      public void addToAreaIPD(MinOptMax idp)

    • toString

      public String toString()
      Overrides:
      toString in class Object
