Description

Overriding loadPDF allows subclasses to load overlays from sources different than File objects, for example from InputStreams or byte arrays (mostly through PDDocument.load overloads).

For example:

Overlay overlay = new Overlay() {
    @Override
    protected PDDocument loadPDF(String pdfName) throws IOException {
        return PDDocument.load(overlayStreams.get(pdfName));
    }
};
