      unicode - utf-32 representation of glyph if appears. Correct value is > -1
      bbox - The normalized bounding box of this Glyph.

    • Glyph

      public Glyph(int width, int unicode)
      Construct a non-mark Glyph object with id -1 and characters retrieved from unicode.
      Parameters:
      width - normalized width of the glyph
      unicode - utf-32 representation of glyph if appears. Correct value is > -1

    • Glyph

      public Glyph(int code, int width, int unicode, char[] chars, boolean IsMark)
      Construct a glyph object form the passed arguments.
      Parameters:
      code - code representation of the glyph in the font file
      width - normalized width of the glyph
      unicode - utf-32 representation of glyph if appears. Correct value is > -1
      chars - The Unicode text represented by this Glyph. if null is passed, the unicode value is used to retrieve the chars.
      IsMark - True if the glyph is a Mark

    • Glyph

      public Glyph(Glyph glyph)
      Copy a Glyph.
      Parameters:
      glyph - Glyph to copy

    • Glyph

      public Glyph(Glyph glyph, int xPlacement, int yPlacement, int xAdvance, int yAdvance, int anchorDelta)
      Copy a Glyph and assign new placement and advance offsets and a new index delta to base glyph
      Parameters:
      glyph - Glyph to copy
      xPlacement - x - placement offset
      yPlacement - y - placement offset
      xAdvance - x - advance offset
      yAdvance - y - advance offset
      anchorDelta - Index delta to base glyph. If after a glyph there are several anchored glyphs we should know we to find base glyph.
