This is the COMPLETELY WRONG WAY to find all fonts in a PDF.
You need to navigate down the "logical tree", starting at the /Catalog and then
going through the /Pages tree, finding all content streams, checking their
resources, etc.

Hello,
I want to use iText to examine existing pdf files, not to create new ones.
While playing around with the ClimbTheTree example I had the feeling that the
functions mentiones in the subject to not work as I would expect them to work.
For example when I want to iterate through all objects and get all the font
dictionaries, I would do something like this:
PdfReader reader = new PdfReader("filename.pdf");
int i = 1;
while (reader.getPdfObject(i) != null) {
if (reader.getPdfObject(i).isDictionary()) {
PdfDictionary pdfDict = (PdfDictionary)
reader.getPdfObject(i);
if (pdfDict.isFont()) {
list.println("Font: " +
pdfDict.get(PdfName.BASEFONT));
}
}
i++;
}
But apparently isFont() always returns false. I'd rather have to check
pdfDict.get(PdfName.TYPE).equals("/Font")
But then what is the purpose of those isFont(), isPages() etc. functions?
Best regards,
