Method Details

createFont
public static BaseFont createFont(String name, String encoding, boolean embedded) throws DocumentException, IOException Creates a new font. This font can be one of the 14 built in types, a Type1 font referred by an AFM 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.
This method calls:
createFont(name, encoding, embedded, true, null, null);
- Parameters:
name
- the name of the font or it's location on fileencoding
- the encoding to be applied to this fontembedded
- true if the font is to be embedded in the PDF- Returns:
- returns a new font. This font may come from the cache

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 may or may not be cached depending on the flag
