public String[][] getAllNameEntries() {
return new String[][]{{"4", "", "", "", fontName}};
} Gets all the entries of the names-table. If it is a True Type font
each array element will have {Name ID, Platform ID, Platform Encoding ID,
Language ID, font name}. The interpretation of this values can be
found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"4", "", "", "",
font name}. |

} Gets the family name of the font. If it is a True Type font
each array element will have {Platform ID, Platform Encoding ID,
Language ID, font name}. The interpretation of this values can be
found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"", "", "",
font name}. |

} Gets the font parameter identified by key. Valid values
for key are ASCENT, CAPHEIGHT, DESCENT
and ITALICANGLE. |
public String[][] getFullFontName() {

} Gets the full name of the font. If it is a True Type font
each array element will have {Platform ID, Platform Encoding ID,

found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"", "", "",
font name}. |
public PdfStream getFullFontStream() {

} You can't get the FontStream of a CJK font (CJK fonts are never embedded),
so this method always returns null. |
