    • readEncodingFromFont

      protected Encoding readEncodingFromFont() throws IOException
      Description copied from class: PDSimpleFont
      Called by readEncoding() if the encoding needs to be extracted from the font file.
      Specified by:
      readEncodingFromFont in class PDSimpleFont
      Throws:
      IOException - if the font file could not be read.

    • readCode

      public int readCode(InputStream in) throws IOException
      Description copied from class: PDFont
      Reads a character code from a content stream string. Codes may be up to 4 bytes long.
      Specified by:
      readCode in class PDFont
      Parameters:
      in - string stream
      Returns:
      character code
      Throws:
      IOException - if the CMap or stream cannot be read

    • getFontMatrix

      public final Matrix getFontMatrix()
      Description copied from interface: PDFontLike
      Returns the font matrix, which represents the transformation from glyph space to text space.
      Specified by:
      getFontMatrix in interface PDFontLike
      Overrides:
      getFontMatrix in class PDFont

    • isDamaged

      public boolean isDamaged()
      Description copied from interface: PDFontLike
      Returns true if the embedded font file is damaged.

    • 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

    • isEmbedded

      public boolean isEmbedded()
      Description copied from interface: PDFontLike
      Returns true if the font file is embedded in the PDF.

    • 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.

    • getStringWidth

      public float getStringWidth(String string) throws IOException
      Description copied from class: PDFont
      Returns the width of the given Unicode string.
      Overrides:
      getStringWidth in class PDFont
      Parameters:
      string - The text to get the width of.
      Returns:
      The width of the string in 1/1000 units of text space.
      Throws:
      IOException - If there is an error getting the width information.
