Method Details

getFonts

public Map<String, FontFamily> getFonts()

getDistinctFontFamilyNames

public static Set<String> getDistinctFontFamilyNames(String path,
 String encoding,
 boolean embedded)

Utility method which uses iText libraries to determine the family name(s) for the font at the given path. The iText APIs seem to indicate there can be more than one name, but this method will return a set of them. Use a name from this list when referencing the font in CSS for PDF output. Note that family names as reported by iText may vary from those reported by the AWT Font class, e.g. "Arial Unicode MS" for iText and "ArialUnicodeMS" for AWT.

Parameters:

path - local path to the font file

encoding - same as what you would use for addFont(String, String, boolean)

embedded - same as what you would use for addFont(String, String, boolean)

Returns:

set of all family names for the font file, as reported by iText libraries
