getFamilyFontName
in classBaseFont
- Returns:
- the family name of the font
-
getFontDescriptor
public float getFontDescriptor(int key, float fontSize)
Gets the font parameter identified bykey
. Valid values forkey

- the parameter in points
-
getFullFontName
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, 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}.- Specified by:
getFullFontName
in classBaseFont
- Returns:
- the full name of the font
-
getAllNameEntries
public String[][] getAllNameEntries()
