For what i can read in the PDF Reference (Third edition), the font desriptor
is a dictionary.
But when i try getting the fontdesriptor with:
PdfDictionary dict = reader.getPageN(i);
PdfDictionary pageResources =
(PdfDictionary)reader.getPdfObject(dict.get(PdfName.RESOURCES));
PdfDictionary fonts =
(PdfDictionary)reader.getPdfObject(pageResources.get(PdfName.FONT));
PdfDictionary fontsdescrip =
(PdfDictionary)reader.getPdfObject(fonts.get(PdfName.FONTDESCRIPTOR));
The last line retuns null.
I tryed with:
Set fontkeys = fonts.getKeys();
Iterator fontIterator = fontkeys.iterator();
while(fontIterator.hasNext()) {
PdfDictionary font =
(PdfDictionary)reader.getPdfObject(fonts.get((PdfName)fontIterator.next()));
System.out.println(font.isFont());
}
output:
java.lang.NullPointerException
at com.lowagie.text.pdf.PdfDictionary.isFont(Unknown Source)
at mypackage5.FontsItext.<init>(FontsItext.java:26)
at mypackage5.FontsItext.main(FontsItext.java:37)
should'nt it be a Font ?
and with:
Set fontkeys = fonts.getKeys();
Iterator fontIterator = fontkeys.iterator();
while(fontIterator.hasNext()) {
PdfDictionary font =
(PdfDictionary)fonts.get((PdfName)fontIterator.next()); // Here
System.out.println(font.isFont());
}
output:
java.lang.ClassCastException: com.lowagie.text.pdf.PRIndirectReference
at mypackage5.FontsItext.<init>(FontsItext.java:25)
at mypackage5.FontsItext.main(FontsItext.java:37)
The botton line i have a PDF with a font in it that isnt embedded. and
Acrobat fails when i open the file,
replacing the text with ........
i just need to know which fonts are used in the document and are they
embedded or available, so i can tell before opening the file in acrobat if
there are missing fonts.
Regards,
David

Do:
PdfDictionary dict = reader.getPageN(i);
PdfDictionary pageResources =
(PdfDictionary)reader.getPdfObject(dict.get(PdfName.RESOURCES));
PdfDictionary fonts =
(PdfDictionary)reader.getPdfObject(pageResources.get(PdfName.FONT));
The values in fonts are the actual fonts. Get them with
reader.getPdfObject() because most of them are indirect references.
