    • Method Detail

      • getAscender

        public int getAscender()
        Ascender height is the distance from the character baseline to the top of the character box. A negative ascender height signifies that all of the graphic character is below the character baseline. For a character rotation other than 0, ascender height loses its meaning when the character is lying on its side or is upside down with respect to normal viewing orientation. For the general case, Ascender Height is the character's most positive y-axis value. For bounded character boxes, for a given character having an ascender, ascender height and baseline offset are equal.
        Overrides:
        getAscender in class CharacterSet
        Returns:
        the ascender value in millipoints
      • getCapHeight

        public int getCapHeight()
        Cap height is the average height of the uppercase characters in a font. This value is specified by the designer of a font and is usually the height of the uppercase M.
        Overrides:
        getCapHeight in class CharacterSet
        Returns:
        the cap height value in millipoints
      • getDescender

        public int getDescender()
        Descender depth is the distance from the character baseline to the bottom of a character box. A negative descender depth signifies that all of the graphic character is above the character baseline.
        Overrides:
        getDescender in class CharacterSet
        Returns:
        the descender value in millipoints
      • getXHeight

        public int getXHeight()
        XHeight refers to the height of the lower case letters above the baseline.
        Overrides:
