    • PDType1Font

      private PDType1Font(String baseFont)
      Creates a Type 1 standard 14 font for embedding.
      Parameters:
      baseFont - One of the standard 14 PostScript names

      Throws:
      IOException

    • PDType1Font

      public PDType1Font(PDDocument doc, InputStream pfbIn, Encoding encoding) throws IOException
      Creates a new Type 1 font for embedding.
      Parameters:
      doc - PDF document to write to
      pfbIn - PFB file stream
      encoding -
      Throws:

    • PDType1Font

      public PDType1Font(COSDictionary fontDictionary) throws IOException
      Creates a Type 1 font from a Font dictionary in a PDF.
      Parameters:

  • Method Details

    • repairLength1

      private int repairLength1(byte[] bytes, int length1)
      Some Type 1 fonts have an invalid Length1, which causes the binary segment of the font to be truncated, see PDFBOX-2350.
      Parameters:
      bytes - Type 1 stream bytes
      length1 - Length1 from the Type 1 stream
      Returns:
      repaired Length1 value

    • findBinaryOffsetAfterExec

      private static int findBinaryOffsetAfterExec(byte[] bytes, int startOffset)

    • repairLength2

      private int repairLength2(byte[] bytes, int length1, int length2)
      Some Type 1 fonts have an invalid Length2, see PDFBOX-3475. A negative /Length2 brings an IllegalArgumentException in Arrays.copyOfRange(), a huge value eats up memory because of padding.
      Parameters:
      bytes - Type 1 stream bytes
      length1 - Length1 from the Type 1 stream
      length2 - Length2 from the Type 1 stream
      Returns:
      repaired Length2 value

    • getBaseFont

      public final String getBaseFont()
      Returns the PostScript name of the font.

    • getHeight

      public float getHeight(int code) throws IOException
      Description copied from interface: PDFontLike
      Returns the height of the given character, in glyph space. This can be expensive to calculate. Results are only approximate.

      Warning: This method is deprecated in PDFBox 2.0 because there is no meaningful value which it can return. The PDFontLike.getWidth(int) method returns the advance width of a glyph, but there is no corresponding advance height. The logical height of a character is the same for every character in a font, so if you want that, retrieve the font bbox's height. Otherwise 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.
      Parameters:
      code - character code
      Throws:
      IOException

    • encode

      protected byte[] encode(int unicode) throws IOException
      Description copied from class: PDFont
      Encodes the given Unicode code point for use in a PDF content stream. Content streams use a multi-byte encoding with 1 to 4 bytes.

      This method is called when embedding text in PDFs and when filling in fields.

      Specified by:
      encode in class PDFont
      Parameters:
      unicode - Unicode code point.
      Returns:
      Array of 1 to 4 PDF content stream bytes.
      Throws:
      IOException - If the text could not be encoded.

    • getWidthFromFont

      public float getWidthFromFont(int code) throws IOException
      Description copied from interface: PDFontLike
      Returns the width of a glyph in the embedded font file.
      Parameters:
      code - character code
      Returns:
      width in glyph space
      Throws:
      IOException - if the font could not be read
