Here's the program to read fonts:

import java.util.*;
public class DumpFontNames {
static PdfReader reader;
static TreeMap fontMap = new TreeMap();
static final PdfName F1 = new PdfName("FontFile");
static final PdfName F2 = new PdfName("FontFile2");
static final PdfName F3 = new PdfName("FontFile3");
public static void processResource(PdfDictionary resource) throws
Exception {
if (resource == null)
return;
PdfDictionary xos =
(PdfDictionary)reader.getPdfObject(resource.get(PdfName.XOBJECT));
if (xos != null) {
for (Iterator it = xos.getKeys().iterator(); it.hasNext();) {
PdfDictionary xo =
(PdfDictionary)reader.getPdfObject(xos.get((PdfName)it.next()));
processResource((PdfDictionary)reader.getPdfObject(xo.get(PdfName.RESOURCES)
));
}
}
PdfDictionary fonts =
(PdfDictionary)reader.getPdfObject(resource.get(PdfName.FONT));
if (fonts == null)
return;
for (Iterator it = fonts.getKeys().iterator(); it.hasNext();) {
PdfDictionary font =
(PdfDictionary)reader.getPdfObject(fonts.get((PdfName)it.next()));
String name =
((PdfName)reader.getPdfObject(font.get(PdfName.BASEFONT))).toString();
if (name.length() > 8 && name.charAt(7) == '+') {
name = name.substring(8) + " subset";
}
else {
name = name.substring(1);
PdfDictionary desc =
(PdfDictionary)reader.getPdfObject(font.get(PdfName.FONTDESCRIPTOR));
if (desc != null) {
if (desc.get(F1) != null || desc.get(F2) != null ||
desc.get(F3) != null)
name += " embedded";
}
else
name += " nofontdescriptor";
}
fontMap.put(name, null);
}
}
public static void main(String[] args) {
try {
reader = new PdfReader(args[0]);
for (int k = 1; k <= reader.getNumberOfPages(); ++k) {
PdfDictionary page = reader.getPageN(k);
processResource((PdfDictionary)reader.getPdfObject(page.get(PdfName.RESOURCE
S)));
}
for (Iterator it = fontMap.keySet().iterator(); it.hasNext();)
System.out.println((String)it.next());
}
catch(Exception e) {
