Constructor Detail

### PDFFontDescriptor

    public PDFFontDescriptor(java.lang.String basefont,
                             int ascent,
                             int descent,
                             int capHeight,
                             int flags,
                             PDFRectangle fontBBox,
                             int italicAngle,
                             int stemV)

  Create the /FontDescriptor object

Parameters:
  `ascent` - the maximum height above the baseline
  `descent` - the maximum depth below the baseline
  `capHeight` - height of the capital letters
  `flags` - various characteristics of the font
  `fontBBox` - the bounding box for the described font
  `basefont` - the base font name
  `italicAngle` - the angle of the vertical dominant strokes
  `stemV` - the width of the dominant vertical stems of glyphs

Method Detail

### setMetrics

    public void setMetrics(int avgWidth,
                           int maxWidth,
                           int missingWidth,
                           int leading,
                           int stemH,
                           int xHeight)

  Set the optional metrics.

  Parameters:
    `avgWidth` - The average width of characters in this font. The default value is 0.
    `maxWidth` - The maximum width of characters in this font. The default value is 0.
    `missingWidth` - missing width
    `leading` - the desired spacing between lines of text. The default value is 0.
    `stemH` - The vertical width of the dominant horizontal stems of glyphs in the font. The default value is 0.
    `xHeight` - The y-coordinate of the top of flat non-ascending lowercase letters, measured from the baseline. The default value is 0.

### setFontFile

    public void setFontFile(FontType subtype,
                            AbstractPDFStream fontfile)

  Set the optional font file stream

  Parameters:
    `subtype` - the font type defined in the font stream
    `fontfile` - the stream containing an embedded font

### getFontFile

    public AbstractPDFStream getFontFile()

  Returns:
    the FontFile or null if the font is not embedded

### setCIDSet

    public void setCIDSet(AbstractPDFStream cidSet)

  Sets the CIDSet stream for this font descriptor. (Optional)

  Parameters:
    `cidSet` - the CIDSet stream

### getCIDSet

    public AbstractPDFStream getCIDSet()

  Returns:
    the CIDSet stream or null if not applicable
