  • Field Details

    • fontEncoding

      protected FontEncoding fontEncoding

    • forceWidthsOutput

      protected boolean forceWidthsOutput
      Forces the output of the width array. Only matters for the 14 built-in fonts.

    • usedGlyphs

      protected byte[] usedGlyphs
      The array used with single byte encodings.

    • toUnicode

      protected CMapToUnicode toUnicode
      Currently only exists for the fonts that are parsed from the document. In the future, we might provide possibility to add custom mappings after a font has been created from a font file.

      appendDecodedCodesToGlyphsList in class PdfFont
      Parameters:
      list - the list to the end of which decoded glyphs are to be added
      characterCodes - the string which is interpreted as a sequence of character codes. Note, that PdfString acts as a storage for char code values specific to given font, therefore individual character codes must not be interpreted as code units of the UTF-16 encoding
      Returns:
      true if all codes where successfully decoded, false otherwise
