PDFBox - PDF Fonts
Standard 14 Fonts
The PDF specification states that a standard set of 14 fonts will always be available when consuming PDF documents. In PDFBox these are defined as constants in the PDType1Font class.

TrueType Fonts
Embedding TrueType Fonts
PDFBox supports embedding TrueType fonts. Loading a new font is easy.
PDDocument doc = PDDocument.load( ... );
PDFont font = PDTrueTypeFont.loadTTF( doc, new File( "SpecialFont.ttf" ) );
External TrueType Fonts
While it is recommended to embed all fonts for greatest portability not all PDF producer applications
will do this. When displaying a PDF it is necessary to find an external font to use.
PDFBox will look for a mapping file to use when substituting fonts.
PDFBox will load Resources/PDFBox_External_Fonts.properties off of the classpath to map
font names to TTF font files. The UNKNOWN_FONT property in that file will tell PDFBox which font
to use when no mapping exists.
