  Creates new BaseFont

Method Detail

### createFont

    public static BaseFont createFont()
                               throws DocumentException,
                                      java.io.IOException

  Creates a new font. This will always be the default Helvetica font (not embedded). This method is introduced because Helvetica is used in many examples.

  Returns:
    a BaseFont object (Helvetica, Winansi, not embedded)
  Throws:
    `java.io.IOException` - This shouldn't occur ever
    `DocumentException` - This shouldn't occur ever
  Since:
    2.1.1

### createFont

    public static BaseFont createFont(java.lang.String name,
                                      java.lang.String encoding,
                                      boolean embedded)
                               throws DocumentException,
                                      java.io.IOException

  Creates a new font. This font can be one of the 14 built in types, a Type1 font referred to by an AFM or PFM file, a TrueType font (simple or collection) or a CJK font from the Adobe Asian Font Pack. TrueType fonts and CJK fonts can have an optional style modifier appended to the name. These modifiers are: Bold, Italic and BoldItalic. An example would be "STSong-Light,Bold". Note that this modifiers do not work if the font is embedded. Fonts in TrueType collections are addressed by index such as "msgothic.ttc,1". This would get the second font (indexes start at 0), in this case "MS PGothic".

  The fonts are cached and if they already exist they are extracted from the cache, not parsed again.

  Besides the common encodings described by name, custom encodings can also be made. These encodings will only work for the single byte fonts Type1 and TrueType. The encoding string starts with a '#' followed by "simple" or "full". If "simple" there is a decimal for the first character position and then a list of hex values representing the Unicode codes that compose that encoding.
  The "simple" encoding is recommended for TrueType fonts as the "full" encoding risks not matching the character with the right glyph if not done with care.
  The "full" encoding is specially aimed at Type1 fonts where the glyphs have to be described by non standard names like the Tex math fonts. Each group of three elements compose a code position: the one byte code order in decimal or as 'x' (x cannot be the space), the name and the Unicode character used to access the glyph. The space must be assigned to character position 32 otherwise text justification will not work.

  Example for a "simple" encoding that includes the Unicode character space, A, B and ecyrillic:

       "# simple 32 0020 0041 0042 0454"

### createFont

    public static BaseFont createFont(java.lang.String name,
                                      java.lang.String encoding,
                                      boolean embedded,

                               throws DocumentException,
                                      java.io.IOException

  Creates a new font. This font can be one of the 14 built in types, a Type1 font referred to by an AFM or PFM file, a TrueType font (simple or collection) or a CJK font from the Adobe Asian Font Pack. TrueType fonts and CJK fonts can have an optional style modifier appended to the name. These modifiers are: Bold, Italic and BoldItalic. An example would be "STSong-Light,Bold". Note that this modifiers do not work if the font is embedded. Fonts in TrueType collections are addressed by index such as "msgothic.ttc,1". This would get the second font (indexes start at 0), in this case "MS PGothic".

  The fonts are cached and if they already exist they are extracted from the cache, not parsed again.

  Besides the common encodings described by name, custom encodings can also be made. These encodings will only work for the single byte fonts Type1 and TrueType. The encoding string starts with a '#' followed by "simple" or "full". If "simple" there is a decimal for the first character position and then a list of hex values representing the Unicode codes that compose that encoding.
  The "simple" encoding is recommended for TrueType fonts as the "full" encoding risks not matching the character with the right glyph if not done with care.
  The "full" encoding is specially aimed at Type1 fonts where the glyphs have to be described by non standard names like the Tex math fonts. Each group of three elements compose a code position: the one byte code order in decimal or as 'x' (x cannot be the space), the name and the Unicode character used to access the glyph. The space must be assigned to character position 32 otherwise text justification will not work.

  Example for a "simple" encoding that includes the Unicode character space, A, B and ecyrillic:

       "# simple 32 0020 0041 0042 0454"

  Example for a "full" encoding for a Type1 Tex font:

       "# full 'A' nottriangeqlleft 0041 'B' dividemultiply 0042 32 space 0020"

  This method calls:

       createFont(name, encoding, embedded, true, null, null);

  Parameters:
    `name` - the name of the font or its location on file
    `encoding` - the encoding to be applied to this font
    `embedded` - true if the font is to be embedded in the PDF
    `forceRead` - in some cases (TrueTypeFont, Type1Font), the full font file will be read and kept in memory if forceRead is true
  Returns:
    returns a new font. This font may come from the cache
  Throws:
    `DocumentException` - the font is invalid
    `java.io.IOException` - the font file could not be read
