        This will get the default width. The default value for the default width is 1000.
        Returns:
        The default width for the glyphs in this font.
      • getDefaultPositionVector

        private Vector getDefaultPositionVector​(int cid)
        Returns the default position vector (v).
        Parameters:

      • getWidthForCID

        private float getWidthForCID​(int cid)
      • hasExplicitWidth

        public boolean hasExplicitWidth​(int code)
                                 throws java.io.IOException
        Description copied from interface: PDFontLike
        Returns true if the Font dictionary specifies an explicit width for the given glyph. This includes Width, W but not default widths entries.
        Specified by:
        hasExplicitWidth in interface PDFontLike
        Parameters:
        code - character code
        Throws:
        java.io.IOException - if the font could not be read
      • getPositionVector

        public Vector getPositionVector​(int code)
        Description copied from interface: PDFontLike
        Returns the position vector (v), in text space, for the given character. This represents the position of vertical origin relative to horizontal origin, for horizontal writing it will always be (0, 0). For vertical writing both x and y are set.
        Specified by:
        getPositionVector in interface PDFontLike
        Parameters:
        code - character code
        Returns:
        position vector
      • getVerticalDisplacementVectorY

        public float getVerticalDisplacementVectorY​(int code)
        Returns the y-component of the vertical displacement vector (w1).
        Parameters:
        code - character code
        Returns:
        w1y
      • getWidth

        public float getWidth​(int code)
                       throws java.io.IOException
        Description copied from interface: PDFontLike
        Returns the advance width of the given character, in glyph space.

        If you want the visual bounds of the glyph then call getPath(..) on the appropriate PDFont subclass to retrieve the glyph outline as a GeneralPath instead. See the cyan rectangles in the DrawPrintTextLocations.java example to see this in action.

        Specified by:
        getWidth in interface PDFontLike
        Parameters:
        code - character code
        Throws:
        java.io.IOException
      • getAverageFontWidth

        public float getAverageFontWidth()

        Specified by:
        getAverageFontWidth in interface PDFontLike
        Returns:
        The width is in 1000 unit of text space, ie 333 or 777
      • getCIDSystemInfo

        public PDCIDSystemInfo getCIDSystemInfo()

      • encode

        protected abstract byte[] encode​(int unicode)
                                  throws java.io.IOException
