Fonts not embedded in PDFs about icepdf HOT 1 CLOSED

The call to FontPropertiesManager.getInstance().loadOrReadSystemFonts() will read all the system's font and persist the list to disk for later retrieval. Once the list is created font substitution is very quick as the list of know fonts is used for subsequent loads. This works very well for most server side and client-side rendering.

It is possible the get an instance of the FontManager and call readFontPackage(). This method can be fed the class path of font files embedded in a jar. This makes it possible distribute the fonts you want with your application and should avoid going to the file system to scan system fonts. But that said once the font list is created it is very quick to find the correct font for substitution.
