List all embedded fonts in a PDF document

In version v2019R1, we’ve added a public API in our Java PDF Library jPDFProcess to tell whether a font is embedded in a PDF document or not. This is done through a method called isEmbedded in the IFontResource interface, that returns a boolean.

The sample code below will get the list of all font resources in a PDF, loop through them and output the name of the fonts that are embedded in the PDF.

PDFDocument pdf = new PDFDocument("input.pdf", null);
List<? extends IFontResource> fonts = pdf.getResourceManager().listFonts();
for(IFontResource res : fonts)
{
 if(res.isEmbedded())
 {    
   System.out.println(res.getFontName() + " is embedded");
 }
}
