Tilman Hausherr commented on PDFBOX-4375:
-----------------------------------------
Yeah, it make more sense IMHO to add a method {{overlay(Map<Integer,
PDDocument> specificPageOverlayDocuments)}} … This would look somewhat like
this:
{code:java}
public PDDocument overlay(Map<Integer, PDDocument>
specificPageOverlayDocuments) throws IOException
{
loadPDFs();
for (Map.Entry<Integer, PDDocument> e :
specificPageOverlayDocuments.entrySet())
{
if (doc != null)
{
specificPageOverlayPage.put(e.getKey(), doc);
}
}
processPages(inputPDFDocument);
return inputPDFDocument;
}{code}

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