Dear Hesham,
Thank you very much for your response!
The purpose of my question is: I need to find out if all fonts used inside the
PDF are embedded. But if a PDF only contains images and no text, I don't need
to check for embedded fonts. At the moment I'm doing that:
public boolean containsText(String pdfFile) throws IOException {
PDDocument document = PDDocument.load(pdfFile);
PDFTextStripper stripper = new PDFTextStripper();
String text = stripper.getText(document);
if(text != null && text.length() > 0) {
return true;
} else {
return false;
}
}
But if the document is very large, this method can take a while. As soon some
text is found I could already return true. But I couldn't figure out how to do
that.
Best Regards,
Andreas

I remember there was somehow in PDFBox to read some resources from the PDF
and skip others, I don't remember how but I think there's some way to skip
parsing images in the PDF.
Best regards ,
