      Specified by:
      decodeIntoGlyphLine in class PdfFont
      Parameters:

    • flush

      public void flush()
      Description copied from class: PdfFont
      To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call PdfObjectWrapper.makeIndirect(PdfDocument). For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.
      Overrides:
      flush in class PdfFont

    • getCmap

      fontDescriptor - the font descriptor dictionary
      fontName - a name of the font
      isType2 - true, if the font is CIDFontType2 (TrueType glyphs), otherwise false, i.e. CIDFontType0 (Type1/CFF glyphs)
      Returns:
      fully initialized CIDFont

    • getToUnicode
