    • getCID

      public byte[] getCID(String fontName)
      get a single CID font. The PDF architecture (1.4) supports 16-bit strings only with CID CFF fonts, not in Type-1 CFF fonts, so we convert the font to CID if it is in the Type-1 format. Two other tasks that we need to do are to select only a single font from the CFF package (this again is a PDF restriction) and to subset the CharStrings glyph description.
      Parameters:
      fontName - name of the font
      Returns:
      byte array represents the CID font
